Description

Non-cutting order apparatus and method for water pipe repair. {Omitted}

One of the essentials in each home, business building, and industrial site is water, which uses groundwater developed for direct supply from the site, but is usually supplied through tap water pipes from the water treatment plant. ought. Water pipes are usually made of cast iron pipes or steel pipes, and some of them are stainless steel pipes or synthetic pipes. Commonly used cast iron pipes have small diameters ranging from 50 millimeters to several hundreds of millimeters in diameter. Almost all of them are buried in the ground. These water pipes are subsidence of soil, the presence of uneven earth pressure, and the temperature of winter ground. Frequently, breakage leaks were caused by freezing due to the fall of. In the case of such a large leak diameter, it is appropriate to shut off the main main valve and repair the damaged part in the case of large diameter. However, as most water pipes are passed to an area close to the water consumer, a large number of consumers are concentrated. When the main valve is shut off, these concentrated consumers must bear the inconvenience caused by the water shortage, and when the water flow is started by opening the valve that has completed the repair of the damaged water leakage and shut off the water, all the waste water in the water pipes is released at the same time. As a result, the so-called supply of water caused a situation that was uncomfortable. In order to prevent this phenomenon, the supply pipe of tap water is configured like a grid of spider web so that the entire tap water supply is not disturbed even if any part breakage or breakdown of the water valve occurs. However, in order to repair damaged pipes, if the water level valve is too far around the broken water pipes, the water pipes need to be repaired in the absence of water stages. However, the freeze protection device developed in some developed countries was not very successful, and the structure was not complicated, and the operation price of the freeze was not generalized because the purchase operation price was astronomically expensive. In addition, accidents caused by rupture of water supply pipes or water pipes with high water flow rate and high pressure supply water pressure should be promptly repaired. However, when the position of the valve is far away from the damaged part, I had to go through the preparations for working for a long time even in the state. Even when the work is ready, if the work is to be carried out without water in the water supply area, the water supply valve is cut off due to the high flow rate and high water pressure. In the case of large-diameter water pipes to be pushed out of the cut out, the worker had a difficult problem in the state that the main order valve is not locked.

In addition, the technology for forming the branch pipe in the main main pipe in the absence of the stage has been developed and operated, but this technology is effective for the branch pipe work, but there was a lack of technology to replace the main valve.

According to the present invention, when a water pipe is ruptured in some sections and leaks occur, a water repelling device can be temporarily installed in the water pipe at the damaged part so that the water pipe can be quickly repaired without cutting off the entire water pipe in the corresponding section. The present invention relates to a non-cutting order apparatus and method for repairing a water pipe that can be installed without cutting.

The present invention has been invented to solve the above problems of the prior art,

When the water pipe buried in the basement is damaged and leaks occur, the damaged parts can be repaired by installing the equipment for the order without cutting the water pipe at the front and rear of the most recent distance without breaking the main main valve. It is an object of the present invention to provide a device and a method for allowing a quick repair and installed water purifier to be utilized as a water dispense valve in need.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

The present invention can be applied to all water supply pipes, and in this specification, any names thereof will be described as water pipes for convenience.

The present invention is characterized in that the water pipes can be ordered by installing a water repelling device with a built-in shutoff valve made to cut and puncture a certain section at right angles to the water flow direction and shield the space formed by cutting and drilling. . In addition, the water system is composed of a combination of a water valve valve housing equipped with a water flow valve operating horizontally in the water direction and a water valve valve housing assembled by incorporating the water flow valve installed vertically in the water flow direction. It features. In addition, the water supply valve housing or the water blocking valve housing is characterized in that the fixed to the lower support portion installed in the lower portion of the water pipe is integrated.

In addition, the process of the present invention,

Installing the lower support part in the front and back position around the damaged water pipe, and cutting and drilling the water pipe after combining the water blocking valve housing with the lower support part;

The process of installing and ordering the ordering device incorporating the ordering valve,

Characterized in that the water pipe is made to repair and pass through the process.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

When a water pipe is found that is broken and leaks, the excavation work is usually performed by mobilizing an excavator. If the leaked part is identified and the part is damaged, excavate more sections to install the device around the damaged part to secure sufficient working space underground.

At this time, the drainage pump is installed with sufficient capacity to pump the water leaking from the damaged part and the water leaking in the process of installing the drainage device to the ground to prevent flooding of the work space.

After deciding the parts to be installed, mark the position on the water pipes, and then fix the upper high information steel plates with bolts and coupling devices at both ends of the lower support parts, respectively, with the lower support parts placed in the lower part of each water pipe.

The lower supporting part and the upper high information steel sheet are assembled and fixed to each other to reinforce the water pipe itself so as to prevent the complete cutting accident of the water pipe when cutting part of the water pipe and using the guide rod formed on the upper upper information steel sheet. It can be used for the operation or fixing of related devices such as used for cutting guided water pipe cutting.

The lower support part formed the flange wings in the longitudinal direction on the semi-cylindrical body close to 1/2 of the diameter of the water pipe, and machined bolt holes at regular intervals. The bolt hole is processed as a simple bolt hole for bolt nut assembly, but the female screw should be machined when only bolt is assembled.

Inside the lower support part, a rubber packing is attached to prevent damage of the water pipe due to the pressure shock during the assembly fixing process and to increase the adhesion.

In addition, the lower base portion was configured to form a uniform coupling force when assembling and to form the ribs in the rib shape at regular intervals to the lower side for the reinforcement of the lower base body itself.

In addition, in the case of a large diameter, the lower support portion may be configured through a multi-part assembly rather than a conventional 1/2 division.

The flange wings processed with bolt holes are manufactured to have a structure that is not enough to be assembled with the devices that are mounted on the upper part, but the width of the wing is widened in the central part where the water pipe is cut and drilled so as to exceed the width of the water pipe diameter in the future. The valve housing for the order is fixed and prevented from interfering.

In addition, in addition to the hole processing for bolting, one side of the valve valve housing for fixing and the flange wing part for the initial fixing of the valve valve housing are machined with feldspar, respectively, and then drilled together to cut and assemble the water pipes. So that they can be quickly assembled.

In the lower part of the lower support part, the drainage hole should be machined to prevent the device from being damaged by water remaining inside the packing during assembly and maintenance.

The upper high information steel plates fixed to both ends of the lower support part have flange wings formed on the body of the narrow semi-cylindrical body for fixing with the lower support part.

Of course, if the aperture is small, it can be processed as a u-band type.

The upper part of the guide rod was formed to be used for mounting a cutting tool or a jig tool.

When the lower support part and the upper high information steel plate are combined to guarantee the water pipe, the water pipe is cut and drilled using a jig tool. Generally, the cutting punching position of the water pipe is formed by the two upper high information steel plates fixedly coupled to the lower support part. It is the middle part and the cutting depth is 1/2 the diameter of the water pipe. However, the cutting hole position and depth, and the cutting hole width or diameter may be changed depending on the type of the shielding valve to be described later.

The cutting drilling of the water pipe is carried out according to the position and line previously marked by the jig tool. The cutting mill may be a cutting device or a variety of devices such as saw blades and end mills. At this time, it is preferable to use hydraulic pressure or pneumatic pressure for the driving motor to prevent electric shock due to tap water which starts to leak at high pressure from the water pipe which has been cut and started, and may use electricity. In addition, in order to prevent leakage due to high water pressure, it is preferable that the cutting cloth mill is selected to be waterproof.

The width of the cut is usually determined in consideration of the width of the order disk valve. The larger the size, the larger the width of the cutting should be. The drive type of the order disk valve should be a vertical valve or a butterfly valve type with a fixed shaft. The change is made depending on whether the rotation method. In addition, in the case of the ball valve type, it will have a wider cutting perforation shape, and in the case of the cylinder for the order valve, an appropriate size of perforation should be made.

If the cutting method is a rotary tool with a cutting edge using thick abrasive stone or an end mill, you can finish the work to the desired depth with the planned width.However, if you use a cutting saw blade or a cutter using abrasive stone, In order to remove the water pipes which are not removed inside the planned width which is already cut, the water pipes cut at right angles to the water flow direction are removed. The part corresponding to the cut width shall be cut in parallel with.

All cutting and cutting processes are to be carried out in a confined space in order to prevent work disturbances caused by excessive water pressure and increase in the amount of water ejected during the cutting operation.

In addition, the shape of the cutting hole opening may be formed in a circle rather than perpendicular to the water flow direction. In this case, a circular cutting bite or abrasive stone having a size close to or equal to the inner diameter of the water pipe is usually used.

When the cutting punch opening is formed, the water shielding valve housing is coupled to the cutting punch opening.

The water blocking valve housing is formed with flange wings so that the cutting hole opening can be completely covered and can be combined with the lower support part.

In addition, the packing is attached along the edge of the cutting surface of the cutting hole opening to apply a tight pressure in the process of coupling the water blocking valve housing and the lower support so that no leakage occurs even under high water pressure.

Of course, if the water pipe is a steel pipe material other than cast iron pipe or synthetic resin pipe, a separate steel pipe water pipe with flange wings that can be connected to the water blocking valve housing without the lower support part is joined by electric welding to the water pipe for the existing order. You can also proceed later.

In addition, the water blocking valve may have its function by using a conventionally known gate valve.

In addition, the order valve housing will be composed of a fixed rotating shaft and the wing disk valve to simply rotate when the order valve is made of a butterfly valve type.

In addition, in order to maintain the accuracy and shielding high without being affected by the rapid water flow formed in the water pipe, the bottom valve is formed so that the cylindrical cylinder shaft through the bottom of the water valve can be combined. You could do it.

In this case, a separate housing having a tight structure in the lower support portion should be configured.

Each configuration will be described below with reference to the following examples.

Example 1

1 and 2 are perspective views illustrating an example in which the water pipe is cut at right angles to the water flow direction and a lower support portion, a water shielding valve housing, and a water valve valve housing are installed.

Inside the water shutoff valve housing, the top and bottom of the square corresponding to the width of the cutting opening penetrate the structure, and the recessed groove is formed at the side to allow the top and bottom disc valve to move up and down. When the disk disk valve is lowered to drain the water pipe, the upper part of the disk disk valve is intimately contacted with the upper part of the water shield valve housing to prevent water leakage from the upper part even at high water pressure. On the side of the water blocking valve housing, a disk valve box was attached to the side opening to operate the water blocking valve installed inside the disc valve box into the water blocking valve housing.

When the disc valve box coupled to the side opening rotates the disc valve handle, the spindle connected to the water blocking valve rotates, and the water blocking valve moves forward and backward through the cutting opening of the water pipe inside the water supply valve valve housing. Block the coming tap water.

A water drain valve is installed at the bottom of the water shutoff valve valve housing to allow the chip or scale separated from the water pipe to be discharged to the outside during the cutting and cutting of the water pipe, or partially leaked from the inside of the water shutoff valve housing during the disc valve operation. Tap water can also be removed and discharged. In this case, since there is a water pressure of about 5 kilograms per square centimeter inside the water pipe, it is possible to easily discharge the cutting chip when there is an opening through the drain valve near the cutting section.

In addition, the water supply valve is inserted into the cutting hole opening in the lower part of the water supply valve, and is inserted into the water pipe, thereby forming a circular opening which is smaller than the internal diameter of the water pipe so that the water can be passed. It is possible to install the disc valve guide frame that constitutes the disc valve groove for the guide function of the disc valve for the order and the function of preventing the disc valve from being separated by the high water pressure inside the water pipe.

The disc valve guide frame is pressed under the water pipe when a hard packing plate is installed at the bottom to fix the water blocking valve housing to the lower support part. Leakage did not occur through.

Hurenji wing portion was configured to cover the cover plate on the top of the water-shielded shield housing.

In order to order the water pipes, the water-discharging valve housing is combined with the water-discharging valve valve housing.

The order disk valve housing has a built-in order disk valve inside, and an alternative form is a known gate valve.

However, the shape of the disk valve for the water-drilling is whether the shape of the cutting hole opening is a rectangular shape formed by cutting at right angles to the water flow direction or a circular shape which is drilled close to or the same as the diameter of the water pipe and the water shielding inside the water pipe. It depends on the type and type of disc valve guide frame installed integrally with the valve housing.

In particular, when the disc guide frame is not used, the valve packing of cushioned rubber material is inserted around the disc valve in order to prevent the perfect order due to the scale or surface roughness of the inner surface of the water pipe. In order to prevent water leakage, it is effectively prevented from being leaked when pressed in the Of course, after the cutting drilling process through the cutting hole opening to polish and polish the scale and surface inside the water pipe by using a grinding stone and brush, it is possible to improve the adhesion in the future when the disk valve contact or the disk valve guide frame is bonded.

Example 2

FIG. 10 is a cross-sectional view illustrating an example in which a circular perforation part having a size close to or the same as an inner diameter of a water pipe is formed in a water pipe by applying Embodiment 2 of the present invention. After installing the lower supporting part and the water blocking valve housing in the water pipe, use a cloth mill to form a circular perforation in the water pipe, and then advance the disk valve in the water shield valve housing to shut off the tap water, and then remove the water mill. Done.

The through part connected from the lower part to the upper part of the water blocking valve housing is formed in a circular shape having a size close to that of the circular hole which drills in the water pipe.

After that, the order valve housing will be installed.

It is composed of a cylinder valve, cylinder shaft, and cylinder cylinder valve cylinder in the cylindrical valve housing, and a cylinder operated by an operating handle or a pressure fluid.

The lower part of the valve for water is composed of a female thread, and the outer part is the same as the inner diameter of the water pipe, and the lower rubber packing containing the male thread is assembled.

A cylindrical rubber sleeve made of rubber or synthetic resin having a certain thickness and excellent elasticity and resilience is to be fitted on the outer circumferential surface of the valve for the valve. The upper part of the valve is fitted to the cylinder shaft, and it is configured to be able to move shanghai separately, and the rubber o-ring is inserted on the outer circumference and the outer diameter of the valve is close to the cylindrical rubber sleeve. The pressure piston is constructed to prevent the rubber sleeve from escaping upward. In the case of Example 2 configured as described above, in order to operate the water valve, the disc valve of the water shielding valve housing is first retracted to secure a passage between the water pipe puncturing portion and the water valve valve housing, and then the gate valve structure of the water valve valve is known. The cylinder shaft, which is a component of the order valve, is lowered by using a cylinder operated by a pressure fluid or by rotating an operation handle formed by a pressure fluid.

At this time, the water level valve is lowered and the lower rubber packing is compressed on the lower inner circumferential surface of the water pipe, and then the pressure piston is further lowered by using a separate operation handle for pressure piston or a cylinder using a separate pressure fluid. Cylindrical rubber sleeve in the swells downwards and swells in the lateral direction to fill the inner circumferential surface of the water pipe to secure watertightness.

The o-ring installed at the top of the valve ensures easy operation of the valve while preventing leakage to the top of the water pipe.

Example 3

12 is a cross-sectional view illustrating the third embodiment of the present invention.

In the case of Example 2, if the diameter of the water pipe is not large, it can be effectively ordered. However, in the case of the medium-large pipe with a water pipe size of more than 300 mm, the elastic restoring force of the cylindrical sleeve is limited. You will have to lose.

As described above in Example 2, the water-repellent valve housing is installed in a state where the water-blocking valve housing is installed.

The order valve is installed inside the order valve housing, and the order valve is configured as follows.

Inside the cylindrical shaft, a pressure fluid pipe to which pressure fluid can be supplied is formed at the center thereof, and a lower rubber packing having the same structure as in the above-described embodiment 2 is installed on the lower surface thereof.

The rubber expansion tube of the cylindrical body is installed on the outer circumferential surface of the cylindrical shaft, and is fixed so that there is no leakage under high pressure by using a tube band or a crimping rib. A protective cover is installed on the outside of the rubber expansion tube to prevent the rubber expansion tube from expanding and bursting without limiting the rubber expansion tube. The protective cover may use woven fabrics, with the addition of thin iron cores in the weaving process to increase strength.

The rubber expansion tube is expandable while the protective cover is not expandable, but the rubber expansion tube must be expanded at least enough to shield the water pipe, so the protective cover is fixed on the upper part of the rubber expansion tube before it is installed on the water valve. In the circumferential direction and up and down in each direction to form a corrugation so that when the rubber expansion tube is expanded can be made smoothly.

In addition, it is possible to form a cylindrical cylinder in the lower support portion and to allow the rubber expansion tube to be expanded inside the water pipe while lowering the cylindrical shaft to the cylindrical cylinder. Of course, the lower sealing plate is sandwiched between the rubber packing to prevent leakage. In this case, the cylindrical shaft is inserted into the cylindrical cylinder of the lower support housing, so that the water level valve is operated stably under rapid water flow.

However, when the drain valve housing is finished and the drain valve housing is removed from the drain valve housing, the drain valve is retracted from the water pipe when the drain valve housing is finished. The expanded rubber expansion tube can be restored to its original shape by the restoring force. However, since the protective cover is not restored to its original condition, a separate restoration rubber band should be fixed to the protective cover on the outer circumference of the protective cover to help this.

In addition, in order to accelerate the circular restoration of the rubber expansion tube and the protective cover, the inside of the cylindrical shaft may be formed under negative pressure by connecting a pressure fluid tube to a vacuum pump.

Example 4

15 is a sectional view drawn to explain the fourth embodiment.

As described above in the second and third embodiments, the water-repellent valve housing is installed in a state where the water-receiving valve housing is installed.

The order valve is installed inside the order valve housing, and the order valve is configured as follows.

The cylinder part is formed at the center of the cylindrical shaft, which is the main body of the valve, and the incision is made to the lower end so as to have a constant thickness width so as to form a symmetric cylindrical recess in each side. At the bottom of the cylindrical shaft, the lower rubber packing described in the second and third embodiments is installed.

The cylinder portion is to form an opening in the vertical direction penetrating the cylindrical groove portion.

Cylindrical grooves cut in the cylindrical shaft were assembled by inserting grooved steel pieces fixed with rubber packing plates. The rubber packing plate is composed of hemispherical rubber plate with the bottom cut off made of rubber or synthetic resin with excellent elasticity and resilience in the center.

In addition, the grooved iron piece is composed of both sides and the back side of the iron plate, and the iron plate is attached to the iron plate on the back side of the iron plate, respectively, installed in the upper and lower springs so that the grooved iron piece is inserted into the cylindrical groove in the usual time and easily after the action It was possible to restore the original position. Moreover, the side was made into the form which attached the straight rubber band.

In the fourth embodiment configured as described above, when the water valve is operated, the water valve is inserted into a circular opening punched into the water pipe through the circular opening configured in the water blocking valve housing.

After the insertion is completed, press the lower rubber packing and operate the well-known operation handle or pressure fluid cylinder installed in the valve valve housing, and the first stage shaft piston is inserted into the cylinder formed in the center of the cylinder shaft of the valve. At this time, the outer circumferential surface of the shaft piston is pushed on one side of the hemispherical protrusion, and the rubber packing plate moves forward toward the inner circumferential surface of the water pipe. Axial pistons are machined into a conical shape of the lower outer circumference so that they can be easily operated between hemispherical protrusion pieces installed in two concave convex pieces at initial insertion.

When the 1st stage piston piston is installed, the 2nd stage piston piston is lowered and the 2nd stage piston piston is pushed more strongly to the grooves to the outside to pressurize the inner circumferential surface of the water pipe so as to prevent leakage.

At this time, the axis piston can be used as one axis without dividing the steps.

Example 5

Fig. 22 is a perspective view drawn for explaining the fifth embodiment of the present invention.

In the above, the upper cover housing is installed to be fixed to cover and fix the entire lower support portion in the state without installing the upper high information steel sheet in the above-described lower support portion. In this case, the lower support part and the upper cover housing are configured to have a sufficient length, and even if the water pipe is completely cut, it is to be combined in a structure that does not cause a phenomena or leakage.

The upper cover housing is configured to constitute a water passage shielding valve housing as described in the first to the fourth, and to install the flange wings and the cover plate on the upper portion thereof. Inside the upper cover housing, an opening for a disc valve, a cylindrical valve or a ball valve is formed so that the order valve can be operated up and down.

In this case, the lower support part and the upper cover housing are combined at both positions centering on the water pipe where the water leaks due to breakage, and then the cutting drilling tool is installed on the flange wing installed in the upper cover housing while the water valve is retracted. Start cutting drilling. When cutting, the cutting is made to a size larger than the diameter of the water pipe and penetrates through the lower portion of the water pipe so that the water pipe is completely cut inside the lower support part and the upper lid housing. The inside of the lower support part has a lower cylindrical cylinder part with a cutting punch size, and a separate guide recess is connected to the lower support part and the upper cover housing so that the water valve can be operated in a watertight manner.

At this time, using a separate cutting tool may simply cut the water pipe to a constant width perpendicular to the water flow direction.

With the water flow valve shut off and leaking to the outside, the water supply valve housing is re-installed and fixed at the position where the cutting drilling tool was installed, and the water flow valve is reversed and the water level valve is operated to operate the water valve. It is done.

At this time, due to the frictional resistance acting on the surface of the water pipe in the buried state and the firm coupling of the lower support part and the upper cover housing, the phenomenon of the lower support part and the upper cover housing being pushed out can be suppressed. In addition, in order to prevent the lower support portion and the upper cover housing from being pushed outwardly, the latch hole is formed in the same position when the lower support portion and the upper cover housing are combined, and the support hole is deeply grounded through the latch hole. The lower support and the upper cover housing are combined with pipe bands so that the lower support and the upper cover housing can be fixed together to prevent the lower support and the upper cover housing from being separated from the water pipe from high water pressure. Alternatively, a separate, wide width fixing pipe band may be attached to the water pipe and the hooks or wires between the clasps formed on both sides of the fixing pipe band and the clasps formed on the lower support and the upper cover housing. The rope may be fastened and tensioned using a turnbuckle so that it does not escape from the water pipe.

In addition, the drain valve is installed in the upper cover housing to help the cutting tips in the cutting drilling process can be easily discharged to the outside.

In addition, by installing a separate tap water outlet in the upper cover housing, the pipe can be bypassed by bypassing the damaged part even when the water valve is closed, so that the water pipe can be supplied to the tap water user without any problem during the maintenance process. have.

When the repaired water pipe is developed and needs repair, the present invention configured as described above will excavate the surrounding damaged pipe and fix the lower support part at the front and rear positions around the broken pipe, respectively, and use a cutting drilling tool. After forming the cutting hole opening, the water flow valve housing is quickly installed to the lower support part. At this time, the water valve valve housing has the disc valve retracted inside the disc valve box. When the disc valve is advanced by rotating the disc valve forward and backward valve handle in the disc valve box, the tap water discharged to the outside is blocked. . At this time, the remaining or slight leakage of tap water is discharged to the outside through the drain valve so as not to interfere with the work.

Next, install the water-repellent disc valve housing on the water-receiving disc valve housing. When the installation is completed, the disk valve handle of the disk valve box is rotated to retract the disk valve, and then the handle valve is lowered by rotating the handle on the upper part of the valve valve housing. At this time, the water level valve is primarily operated along the recessed portion in the water-receiving valve housing, and when it is lowered into the water pipe, it is operated along the recessed portion of the disc valve guide frame to order the inside of the water pipe.

On both sides of the damaged part, the installation of the water purifier is completed in the same manner as above, and when the water is made, quick water pipe repair is performed in the absence of water leakage.

When the damaged water pipe repair is completed, the handle of the water valve valve housing is rotated to raise the water valve for the upper direction, and the water flow is made inside the water pipe. In this case, if the water drainage device is installed in the water pipe as it is to be used as a distillation valve in the future, the manhole can be installed and managed.If the function of the distillation valve is not needed, the handle of the disk valve box of the water-tight shield valve housing is again used. Rotate the water flow valve forward to confirm that the water has been filled and then remove the water flow valve housing. After that, cover the cover plate to the upper opening of the water supply valve housing, combine it, and cover it again.

In addition, if the water valve is not used for water use but is simply used as a water purifier during the maintenance time, it will be possible to work without installing the disc valve guide frame.

Meanwhile, the present invention may be variously modified and may take various forms as described above in applying the above-described components.

And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

As described above, when the water pipe buried underground is damaged due to breakage of water pipes buried under the ground, the water supply pipe is repaired according to the present invention. It is possible to repair damaged water leaks in a short time by repairing damaged water leaks, and the installed water purifier can be used as a water valve to provide quick and economical water pipe maintenance and repair effects. It is a technology and device that can be applied to cooling water pipes or industrial water pipes as well as water pipes.
