Description

Fitting Fitting Protective Band {PROTECTION BAND FOR PIPE FITTING}

The present invention relates to a pipe protection band, and more particularly, to a pipe protection band for mounting the end of the pipe to protect the precision end of the pipe during the storage and transportation process.

Pipe fittings are pipe fittings that are used to divert from the main pipe and to pipe when changing the pipe direction or pipe diameter. Generally, pipe fitting is manufactured by using steel plate or pipe or molded by forging plate. It is then produced by machining.

Pipe fittings can be manufactured by butt welding, socket welding, thread type and flange flange. Depending on the material, carbon steel, stainless steel, Alloy steel, duplex, and the like.

These fittings are used in nuclear power plants, water and thermal power plants, and in addition, they are used in shipyards, petrochemical plants, central and district heating plants. In these large plants, it is used for piping for steam, water, oil, gas, and air, and is used for changing the direction of the pipe or changing the diameter as described above.

These pipe fittings are made of a small diameter of about 20mm to a large diameter of about 1200mm or more, and can be classified into elbow tubes, tee tubes, reducer tubes, etc. according to their shapes. In particular, the ends of the fittings can be machined to taper at an angle of about 45 degrees, which can be damaged during storage or transportation.

A separate cap or the like is used to protect the end of the fitting, but since the outer diameter and the inner diameter may vary depending on the intended use of the fitting, it is difficult to have a perfect cap for the fitting of all dimensions.

The present invention protects the end of the precision machined fittings, but provides a protective band that can respond to various inner and outer diameters of the fittings.

The present invention provides a protective band that is mounted at the end of the fitting but stably adheres to the end of the fitting and does not come off.

The present invention maintains flexible elasticity regardless of the season, and provides a protective band that is easy to use even in cold winter.

According to an exemplary embodiment of the present invention, the protective band for protecting the end of the fitting, the middle portion corresponding to the end surface of the tube, the inner surface extending from one end of the middle portion and in close contact with the inner surface of the tube The contact portion, an outer surface contact portion extending from the other end of the intermediate portion and in close contact with the outer surface of the tube, and a projection projecting toward the outer surface contact portion from the end of the inner surface contact portion.

The soft synthetic resin, which is a mixture of polyvinyl chloride (PVC) and a plasticizer, may be extruded and molded for a long time, and the middle part, the inner surface contact part, the outer surface contact part, and the protrusion part may extend from side to side in the extrusion process. These bands can be cut and used only as needed and can be secured along the perimeter while receiving the ends of the fittings.

The size of the middle part may be determined according to the thickness of the cross section of the tube, and when the size of the middle part is determined, the perimeter of the cross section may be accommodated with a protective band without the need for a separate cap to be protected. In addition, since the protrusions maintain a thicker thickness than the inner surface contact portion, the band can be prevented from peeling off from the inner surface, and the pressing force by the protrusion increases, thereby increasing the frictional force.

The pipe fitting protection band of the present invention can protect the end of the precision machined pipe fitting irrespective of the outer diameter or the inner diameter. There is a number.

In addition, since the soft polyvinyl chloride is used as a material, it maintains a flexible elasticity regardless of the season, and the band does not harden even in the cold winter, and it is always convenient to maintain the use condition.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by quoting contents described in other drawings under such a rule, and the contents repeated or deemed apparent to those skilled in the art may be omitted.

1 is a perspective view for explaining the fitting band and the use example according to the present invention, Figure 2 is a cross-sectional view of the fitting pipe protection band of Figure 1, Figure 3 illustrates the use case of the fitting pipe protection band of Figure 1 It is a section for.

1 to 3, the fitting fitting protection band 100 includes an intermediate part 110, an inner surface contacting part 120, an outer surface contacting part 130, and a protrusion 140.

The intermediate portion 110 corresponds to the end surface of the tube and roughly corresponds to the thickness of the tube cross section. In general, depending on the size of the middle portion 110, 10mm, 15mm, 20mm. The width of the intermediate part 110 may be determined in various sizes such as 30 mm and 45 mm.

The inner surface contact part 120 and the outer surface contact part 130 extend in the same direction at an approximately right angle or an acute angle with respect to the intermediate part 110. The inner surface contact portion 120 and the outer surface contact portion 130 extend in a c-shaped or triangular shape together with the intermediate portion 110, but are preferably formed in a substantially triangular shape for stable contact of the contact portions. In fact, the intermediate portion 110, the inner surface contact portion 120, and the outer surface contact portion 130 is manufactured by extrusion molding using a synthetic resin, they can be cured to be naturally collected inward in the process of curing at room temperature.

The protrusion 140 is formed to protrude from the end of the inner surface contact portion 120 toward the outer surface contact portion 130. An end portion of the inner surface contact portion 120 is formed to have a thicker thickness than the other portion by the protrusion 140, and may have a higher elastic force than other portions of the inner surface contact portion 120. Therefore, once the band 100 is mounted to accommodate the end face of the fitting (), it is possible to prevent the band 100 from being peeled off from the inner surface contact portion 120.

In addition, since the protrusion 140 protrudes from the inner surface of the inner surface contact portion 120 toward the outer surface contact portion 130, the protrusion 140 comes into close contact with the inner surface of the tube at a higher pressure than other portions, and the band has a relatively high frictional force. The departure of the 100 can be prevented.

In particular, since the end of the protective band according to the present invention does not form a closed curve as a free end, peeling of the band may occur from the end of the band. However, the protrusion 140 may increase the basic elastic force, and when the ends of the band ends overlap each other, the band 100 may be effectively prevented from being peeled off by the mutual locking.

The band 100 may be formed by mixing polyvinyl chloride (PVC) with dioctylphthalate, stabilizers, and other additives. Preferably, based on 58 parts by weight of polyvinyl chloride, 30 to 40 parts by weight of dioctylphthalate and 5 to 8 parts by weight of a stabilizer may be provided by mixing, and a pigment or the like may be mixed therein. In the case of the component can maintain a stable adhesion regardless of the season, and can provide a flexible elastic force even in the cold winter to prevent the band from hardening or cracking.

Figure 4 is a cross-sectional view of the fitting for protecting the band according to another embodiment of the present invention.

Referring to FIG. 4, the pipe fitting protection band 200 also includes an intermediate part 210, an inner surface contact part 220, an outer surface contact part 230, and a protrusion 240. However, the protrusion 240 is formed inward from the end of the inner surface contact portion 220, even in this case can be expected to prevent the peeling of the band by the above-described protrusion 240, increase the frictional force, strengthen the binding force by mutual overlap, etc. have.

The outer surface of the inner surface contact portion 220 and the outer surface contact portion 230 may be formed with a plurality of irregularities 222, 232 parallel to the longitudinal direction of the band 200, these irregularities 222, 232 are uniform or uneven It can be formed at one interval.

As described above, the present invention has been described with reference to a preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
