Abstract

Apparatuses and processes for sealing leaks and for connecting pipes, tubes, profiles, cables or joints. With the aid of at least one pressing/holding tool (1) according to the invention, it is possible to quickly and effectively eliminate leaks, in particular oil and gas leaks, even in deep-sea areas, at low cost and with little risk. In addition, pipes, tubes, profiles or cables can be connected to one another and/or to joints using the invention, and in this way even complex structures can be created.

Description

Devices and methods for sealing leaks and connecting pipes, hoses, profiles, cables or joints

The invention relates to a device according to the preamble of claim 1.

Pipe / hose leaks, especially those in the deep sea, are to this day only conditionally controllable and always a technical challenge. This is illustrated by the example of the oil spill in the Gulf of Mexico, 20.04.2010.

The object of the invention is to enable a quick, low-risk sealing of leaks, in particular those such as those mentioned above. In addition, the new technology is intended to connect pipes, hoses, profiles or cables with each other and with connection points.

The technique is essentially based on a mechanical / hydraulic closure mediated by a so-called press / holding tool according to the invention.

The hydraulic system generates a large contact pressure for the press / holding tool, so that even under high pressure escaping liquids, substances or gases can be pushed back and the leak can be closed. At the same time, the strong contact pressure offers a very good resistance to withdrawing forces acting on the pressing / holding tool.

After sealing of an oil leakage according to the invention, the borehole can continue to be used; a Zubetonieren deleted.

With the aid of the invention, it is also possible to close leaks in above-ground pipeline systems without the pipe system necessarily having to be emptied or depressurized.

In the event of an explosion or fire hazard, the remote-controlled version should be used. Security requirements, e.g. are necessary for welding, omitted according to the invention.

The devices and methods presented here all use at least one

inventive press / holding tool.

These press-holding tools are characterized by a combination of a holding function and a pressing function. The holding function may, for example, hold the device in place. It may also hold and support the article to be pressed (e.g., the inner liner 36a and b) and / or the article to be pressed (e.g., the leak tube)

Connect or allow a leak closure. It can also be attached to a gripper arm and bring the items mentioned, position, hold and finally press.

Unless the compressed object after pressing does not independently hold on the pressed object takes over the press-holding tool a holding function, such as a clamp or clamp.

The holding function can also serve as an abutment for the pressing function.

The compression is used to actually seal the leakage or the connection between the Pipes, hoses, profiles, cables or joints. Either a closure is pressed over the leak or, if necessary, after preparation of the leak tube

Closure device / valve device Attachment device tightly attached to the leakage tube by pressing. In addition, this closure can be glued, lasered, welded or additionally attached in any other conventional manner. The joining of profiles, for example, by a the junction of two profiles bridging, to be pressed

Connecting element.

The part to be pressed is usually integrated in the press-holding pliers and possibly interchangeable. In the already known pressing tongs the part to be pressed must be mounted on the object to be pressed and then comes in contact only with the pressing tongs for the moment of pressing.

The holding function and the pressing function can be performed at the same time by a pressing / holding tool or distributed to different sub-tools or more

Press / holding tools.

Pure pressing tools for permanent connection by pressing workpieces are already known in the heating plumbing sector.

The pressed parts are permanently pressed and should also be kept permanently close to the pressed part. Since the pressing tool is removed after the pressing, the compressed part must withstand the forces, in particular the pressure forces, alone. For such a part to be compressed at all, it must be made of a resilient material. In addition, it should be stable and provide sufficient resistance against peeling forces. These two

Targets can not be agreed, so all are on the market

Pressing systems Compromise solutions.

According to the invention, an optimum flexible compressible fitting adapted to the sealing properties may e.g. be used in the form of a cuff or leak cover, it must not be taken to sufficient stability or a permanent independent stop after pressing. The hold can be taken in a variant only by the press-holding tool. The pressing function of the device according to the invention brings in this variant, the cover only in an ideal contact with the pressed part. In another variant, the pressing function by mechanical force causes a largely permanent deformation of the pressed article. With optional additional seals / gasketing materials, the press function can result in a lasting hold on the pressed part. This is supported by the holding forceps or parts thereof.

The press-holding tools can be optimized for the transmission of power to the pressed and / or the pressed article. They are usually made of sturdy, non-compliant material. If parts of the press-holding tools are left after being pressed, they may e.g. held by a locking mechanism in the pressing state. Alternatively, these parts can also be connected to the pressed object subsequently

(welded, lasered, cast in, bolted, etc.)

The conventional pressing tools can only be used if the pipe connection is pressure-free. The sleeves must then be pushed separately over the leak tube before pressing. Only then can such a pair of pliers be used.

According to the invention, a pressure-free position is not necessary. The parts to be pressed can be part of the press-holding tool and thus be mounted in one operation.

The conventional technique further assumes that the workpiece to be pressed is flexible, so that it can be deformed at all and thus pressed. Furthermore, this must be too pressing part to be designed less stable than the pressed part, so that in the pressing process, the pressed part is not damaged. For this reason, the pressing technique is used only in pipes of relatively soft material such as copper or relatively soft, compliant plastic. This sets its limits to the possible maximum pressure loads of such closure systems or pipe connections. For high pressure loads, this technique is not designed.

According to the invention now under high pressure pipes can be connected from less flexible material or leaks are closed at this. Not the compressed object alone seals or bonds, but the entire system of compressed

The object and press-holding tool (s) or system of pressed material with parts of the press-holding tools.

In some cases, the novel tools can also have a more stable construction than the pressed article (for example the profiles, tubes, etc.)

Pipe closures or connections withstand the highest loads.

Additional connections (see no. 41 in the legend) of the press-holding tools with each other or with joints can result in more stable structures than the structures created by joining the original objects. The profiles and parts of the press-holding tools to be pressed first are then only a relatively unstable framework for the actually supporting second construction, which in turn can be created by means of press-holding tools.

For the purposes of this invention, connection points are not only the connectors of pipes, hoses, profiles or cables, but also the transfer points for electricity, gas, liquids or

Vacuum for suction.

In a further variant, the press-holding device may be designed as a portable device, which may optionally accu-operated, especially on construction sites used. In the construction of a scaffold no longer needs to be screwed. A hand-held press-holding tool can press parts that can be inserted into recesses of scaffolding tubes, and in this way build scaffolding constructions or help to manufacture iron reinforcements. The compressed parts of the press-holding tool can be secured by hand through a split pin. This is removed when dismantling the framework and the locking of the press-stop ewerkzeugteils solved by re-pressing.

A preferred field of application of the invention is the application as a remote-controlled blowout preventer or as an emergency system for defective blowout preventer (cf the accident in the Gulf of Mexico in April 2010). These emergency systems are relatively small and lightweight compared to the emergency dome designs. They are held by the holding function of at least one press-holding tool at the site, a large weight is therefore not necessary.

In the press / holding tools according to the invention, as the name indicates, it is not an exclusive pressing of materials, but a holding function that exerts the pressing / holding forceps itself or a part of the pressing / holding forceps to be pressed. In addition, the press / hold pliers are usually detachable or parts thereof, e.g. the working parts or the

Inner lining of the working parts. However, if desired, it can also be permanently connected to the leakage tube. The conventional pressing tools, however, compress the parts only permanently. In one embodiment according to the invention, a release of the pressing / holding tools or parts thereof is possible after pressing, so that the compressed material from the pipe, hose, profile or cable can be solved to possibly again again to be pressed.

The press / holding tools presented here generally work hydraulically, mechanically, electrohydraulically or electro-mechanically. As a rule, the new devices perform a two-armed ring closure and are therefore also referred to as press / holding pliers. Alternatively, the press / holding forceps arms may touch each other during the closing operation or pass close to each other or be interlocked with each other (see Fig. 9b). Three- or multi-arm designs are conceivable (see Fig. 9 and 10)

To improve the frictional connection of the press-holding devices, a segmentation is provided in particular of the working part / sector region. The individual segments are movably supported for optimum distribution of force across the tube circumference or on the profile

guarantee. Each segment may have its own pressure sensor possibly also an individually controllable hydraulic device for targeted contact pressure control.

It lends itself, at certain intervals, to the pipes / hoses / cables and profiles

Reinforcements or projections / undercuts / recesses to install so that press-holding tools without danger for the objects to be pressed (pipes, cables, profiles, hoses) are fastened and find a better grip.

Alternatively, it is not pressed against the leak pipe, but against one of these

Reinforcements. The reinforcements may have undercuts, protrusions or recesses which may possibly additionally assume an abutment function for the press-holding tools.

The work sectors are usually made of very hard material (usually metal,

Ceramics, special glass, special plastics, etc.). They can also be filled with diamonds in the industry sector. Additionally or exclusively, softer plastics or adhesives are also used. All this serves to find a better grip and / or adjustment when pressing against the leakage pipe. The work branches can be glued, lasered, welded, concreted or joined together in other known ways to be held in the locked holding position. Additionally or alternatively, the

Press / holding pliers are attached in the same way to the leakage pipe.

This can all be done automatically and / or remotely. In one variant, the jaws of the working branches of the press / holding tool can be divided into individual sections and mounted in a movable manner. In this way, the press / holding tool better grip on

Leakage tube find, especially in the event that the leak has projections, undercuts or recesses.

As a rule, only one pressing / holding pliers is used. However, two or more devices can be connected to each other, which can work individually or in combination by means of a control unit. The hold on the leakage pipe is thereby significantly improved and at the same time the leak-beaten pipe / hose is stabilized, similar to a scaffold, (see Fig. 7 or 8 there are several holding tongs in each double version used).

It is advantageous if the press / hold pliers contain pressure sensors that provide accurate

Allow contact pressure. In this way, an optimal grip on the leakage pipe can be achieved without damaging it. The torque wrench principle can also be used.

The fact that the pressing / holding tool remains on the leakage pipe, are permanent large

Holding forces possible. The built-in sensors can also be an individual

Requests corresponding repressing take place. It is also advantageous that the pressing / holding tools and parts thereof, including the pressed parts, can be released again. If only one (locked) holding part is left on the leakage pipe, the holding function can be maintained by this part. The loosened pressing / holding pliers can then be used again with a new branch part. Also, the holding member may be releasably secured (see Fig. 6 No. 14 and 19 of the legend).

Undercuts, protrusions or recesses on the objects to be pressed or pressed reinforce the support of the device as an abutment or by an additional IGemrrifunktion. In addition, they can also improve the seal during compression. Using the example of the defective BOP in the Gulf of Mexico, the large protruding plate-shaped metal area that is present there can be used in the transition of the BOP to the cane tube as an abutment for at least one press-holding device.

The vertical compression can also take place in such cases before the lateral displacement of the closure valve via the leakage opening. In such cases, only the lateral guide rails and boundary areas of the closing valve, which has not yet been displaced beyond the leakage opening, are first pushed laterally over the metal plate and then pressed vertically against the plate-shaped upper metal area of the BOP. Only then is a lateral displacement of the closure valve via the leakage pipe and a closure of the closure valve.

Pressure sensors monitor the entire process. Should there be a risk that the pressure of the escaping oil should destroy the device, valves are automatically opened and a pressure relief is brought about and / or the press-holding device is readjusted.

In addition, the invention offers the possibility to eliminate hose leakage.

The press / holding tools can be used to connect pipes, hoses, profiles or cables. These can be connected to each other by means of the pressing / holding tools through joints. A joint in the sense understood here can also be a transfer point, a flange, for the transfer of liquids, solids, gases or electricity. By connecting several profiles, pipes, etc. complex three-dimensional structures can be built. All this can largely be done remotely controlled and thus without danger to humans. This application variant is helpful, e.g. at the

High-rise construction, bridge construction, construction of high voltage pylons and their wiring,

Underwater construction of a pipeline. Construction and dismantling of nuclear facilities, construction of

Space stations in orbit, space or stations on planets or moons.

If profiles are to be connected, then it is helpful to design the press / holding tool so that it is adapted to the shape of the profile. A corresponding segmentation of

Working parts / industries is an advantage.

The device may be designed for smaller tubes / profiles etc. as a hand-operated device that can be carried by a person. In a further variant, the device on a particular off-road land vehicle, such as a tracked vehicle or a

Crane vehicle, be attached. The device may also be mounted on a watercraft, in particular a boat or underwater vehicle. In addition, it is also attached to an aircraft, in particular a helicopter. This can be used, for example, in hard-to-reach places such as high voltage pylons or high-rise buildings. Particularly in this field of application, a stabilizing system similar to the optical stabilization in cameras or the cannon in an armored vehicle makes sense. Too strong maneuvers due to flight is an automatic emergency opening of the am Helicopter mounted press-holding tool provided.

All mentioned variants can also be remotely controlled or largely autonomous, as

Robotic vehicles, are used.

A special case of these robotic vehicles is given when the system with the help of the holding function of the press-holding device to the tube / hose profile / cable through a

alternately advancing or overlapping a second or further press-holding tool, moved. In this way, the device can independently reach up to the point to be processed. Alternatively, the movement on / on the object can also be done by means of chains or wheels.

This variant is particularly useful for repairs in hard-to-reach areas, such as in buildings or in underground shafts.

The system can also be used to improve the safety of nuclear installations.

Mobile, all-terrain, remotely controllable units can also close pipe leaks in a debris-strewn radioactive contaminated environment or, for example, flexible

Routing and connecting hoses / cables remotely. A 'mobile cooling / pumping system' or 'mobile emergency generator' could be connected. It can also help to pump out radioactively contaminated water.

Helped are already provided in the planning of nuclear facilities or subsequently built standardized transfer / or connection points for example. Electricity or cooling fluid on the outer walls of the reactor. It is also helpful to provide standardized connection options with abutments on the BOPs, pipes / hoses / profiles / cables at predetermined intervals.

For each BOP, piping, pipe, hose, profile or cable system, the appropriate processing, repair and emergency system should be maintained.

The new device is usually mobile and fernhandtierbar. She can be as mobile

Blowoutpreventer, or serve as an emergency system for defective Blowoutpreventer.

For above-ground leaks, this new system is even easier to use, since here the

Pressure ratios are many times lower than in an off-shore leakage.

The new system can even be used to close off burning oil wells. The fire does not have to be extinguished beforehand, it extinguishes in the closure according to the invention. If necessary, these measures can be carried out remotely using a mobile unit.

1st variant

In this variant, the pressing / holding pliers serve as a press-fit connecting piece, here a hopper / cylinder device (see Fig. 1) placed over the leakage, as a stop on the leakage pipe. The usually softer metal of the funnel is pressed against the intact part of the leakage tube and tightly connected with this possibly this is additionally provided with an already known sealing material.

This funnel / cylinder can flow into a special Reiser tube above (see No. 10 of the legend). The press / hold pliers may also be part of the hopper / cylinder device.

The hopper / cylinder with the press / holding pliers can also be mounted inside a large bell / sleeve is slipped over the entire well structures (see Fig. 2), be attached.

For pressure regulation and safety, special, possibly additional, valves which open automatically from a certain internal pressure can also be used after closure.

A further embodiment variant is described in FIG. 14. A sub-tool (30 b) is mounted below the plate-shaped portion of the BOPs (6 a) and serves as an abutment for the device acting on the valve and thus on the sub-tool (30 a) exerting forces.

Alternatively, the pliers can be pressed against each other (position 33a), simultaneously with the dish-shaped area (position 33b) or only against 6a (position 33). Here, the press-holding device (30) is equipped not only with two part tools, but also with opposite holding systems or hydraulic / screw systems (32). This type of execution generally serves to stabilize the devices according to the invention on the tube / hose / profile or cable and ensures a uniform force transmission of the press-holding tools on the object to be pressed.

Method.

In the first step, a compressible connection piece, esp. A funnel / cylinder device is slipped over the leak.

If a valve is located at the top, it should be initially opened to facilitate placement of the device over the leak tube. The substances / gases flowing out of the leak can then escape through the valve during the fastening phase. The

Funnel / cylinder device consists in the lower part of a pressable material, preferably made of metal or plastic.

In the second step, the device is pressed firmly by means of the press / hold pliers in the lower area with the leakage pipe and held by the press / holding pliers or parts thereof. The

Holding forceps or parts of the pressing / holding forceps can be additionally fixed to each other / and / or to the leakage pipe.

Alternatively, a second (part) tool can be placed below a projection (see FIG. 14) or clamped into a recess and additionally pressed. This

Tool serves to hold the overall construction and can serve as an abutment in this position.

In the third step, the valve is closed in a controlled manner and the oil is pumped out.

Alternatively, the upper area can also be closed by a press / holding pliers with flat branches.

2nd variant

In a second variant, the pressing / holding forceps is first fastened as a pure holding forceps below the leakage point of the leakage tube from the side (compare FIGS. 3 and 14). The pressing / holding forceps is part of the entire device, which also has a valve for closing the leakage tube. In a second, optional step, the leakage tube can be straightened by means of a saw / separator (see FIG.

In the next step, this valve is passed over the defective pipe from the side

pushed / turned / folded and pressed like a lid against the holding forceps, the

Press / holding tool now also performs a pressing function. It is advantageous if that Valve on the side facing the leakage pipe a softer metal, a plastic, rubber seal, etc., to compensate for unevenness or material differences and generally allow better tightness and / or grip. It is also advantageous if at least one annular elevation tube is attached to the underside of the valve. This serves to increase the tightness during pressing, but also the stability of the repair site. This collection tube may have a larger diameter than the leak tube and be pushed over the leak tube. Advantageous is a design with a smaller diameter. This tube is pushed into the leakage pipe and stabilizes the leak-beaten pipe and can serve as an abutment for pressing / holding pliers. In this case, the leakage pipe is pressed between the press / holding pliers and the internally inserted valve extension. Furthermore, it is advantageous, a larger diameter annular collection tube and in this one in the

Provide diameter slightly smaller annular elevation tube (see Fig. 11 and 12). The annular bumps can ultimately be carried out like two nested tubes. When placed, the leakage tube slides between the outer and inner annular bumps tubes and can when (re) pressing the leak tube

give additional support. In this way, hoses can be closed. Optionally, all types of known sealing materials can be used in the area between the inner and outer elevation / tube.

Alternatively, the valve device may be pressed not only against the interface of the leak tube, but also simultaneously or alternatively against protrusions of the leak tube or the BOP.

The press / hold pliers according to the invention serve as a counterhold for the pressing of the lid or valve. It is also advantageous to have built-in pressure sensors to prevent excessive pressure of the valve on the leakage pipe.

Finally, the valve is closed and the oil can be pumped out.

3rd variant

The third variant is similar to variant two.

However, before the valve / cover is pushed / rotated / folded over the leakage pipe, the pipe is flushed by means of a saw / a cut-off grinder / a separating tongs, etc.

cut off / separated (see Fig. 5). This can be done automatically or remotely. The smooth interface allows a simpler and denser closure of the leakage tube through the valve device.

4th variant

Squeezing of leaking tubes / tubes made of softer, deformable material, plastic, metal, etc.

Advantageous is a press / holding pliers with flat branches.

For stabilization, further pressing / holding tongs with holding constructions can be used (compare variant 2)

5th variant To bridge a pipe / hose leak or to connect

Tubes / Hoses Profiles / Cables the above mentioned devices and methods can be used in the same way.

If necessary, in the event of a pipe / hose leakage, before the seal, the leak point must be prepared by means of two separation points, to the right and left of the leak. Two compressible connecting pieces, in particular cylinder or funnel devices, if necessary with valves, are attached to the interfaces, which can then be connected to one another (see Fig. 7).

Alternatively, two telescoping attachments can be used (see Fig. 8).

Advantageously, it is in the leak tube / tube initially a stable tube with less

Insert diameter and press from the outside with a pressing / holding pliers (see the bottom of the valve Fig. 11, but there with additional outer bead / tube).

In a three-armed variant, the double arm pushes right and left of the leak over the pipe. The middle counter-arm is pushed exactly over the leak (see Fig. 9 and 10).

To seal a larger leak, the gripper arms can be constructed larger or provided with special Abdicht plates. Figs. 9 and 10 show a case of a particularly large lining of the inner branches of the press / hold pliers (No. 24 of the legend). With several plates, these then slide over each other and are connected by the pressing pressure with each other and with the tube.

The connection of pipes / hoses / profiles or cables with each other and with a

Junction describes Fig. 13. At the junction 31, a sub-tool 30b clamped in an incision 31a. This structure improves the hold of the press-holding tool on the

Joint. 21b shows in simplified form the complex connection and 21a the simple direct connection between the connection points 31. The complex connections can

For example, be three-dimensional framework structures that can serve to build space stations. The execution can be remote-controlled or largely autonomously controlled.

Another variant works with connectors to be pressed. For example, profiles with press-holding pliers which assume the gripper arm function are held together on the front side (alternatively overlapping, inserted into one another or hooked) and connected to one another by a special press-holding tool (compare FIGS. The profiles are usually made of metal or plastic. In a special case, in particular for the colonization of the moon or Mars, they can also consist of a special concrete. According to the invention, the concrete parts produced on site would be interconnected. The lower gravity would make the work much easier. On earth, only newly developed, lightweight but stable concrete mixtures could be used, for example with the addition of plastics.

Fig. 15a shows a section (section line 39 of Fig. 15b) by a pressing / holding device for connecting two profiles. The inner liners (36a and 36b) are crimped over the seam and adjacent profile areas.

Fig. 15b shows a plan view of a press-holding tool 1, which connects two profiles together, two interconnected profiles, the working parts / branches 35a and 35b were left, the hydraulic and screw system, however, removed, it can be reused. The dashed lines illustrate the optional connection of the press / hold forceps with each other through additional connectors.

In this way, complex and resilient structures can also be created very easily and quickly. If necessary, these can also be dismantled again and then re-installed at another location. execution Beipiele
