A fixed block having a hollow structure to surround the entire periphery of the pipe assembly and spaced apart along the longitudinal direction of the pipe assembly; A groove formed on the surface of the fixed block contacting with the pipe assembly so as to be filled with the test water to be leaked; A connecting member connecting between the fixed blocks; A watertightness test apparatus having an expansion deformation preventing function of a pipe assembly constituted by the above-mentioned watertight test apparatus is provided.

Description

[0001] The present invention relates to a watertight test apparatus capable of preventing expansion deformation of a pipe assembly,

The present invention relates to a watertightness test apparatus having a function of preventing expansion deformation of a pipe assembly, and more particularly, to a watertightness test apparatus having a watertightness test apparatus having a function of preventing expansion and deformation of a pipe assembly, So that the pipe assembly is prevented from being inflated and deformed by the pressure applied in the watertightness test.

Generally, many pipes such as drinking water line, steam line, various high pressure lines are connected to the ship. Especially, high pressure pipes are checked for water leakage through water tightness test.

Generally, when the connection length is long, the joint pipe is welded between the high-pressure pipes to match the connection length. In this way, leakage is also checked for the connection portion between the high-pressure pipe and the joint fire.

When a watertight test is performed on a pipe assembly connecting a high-pressure pipe and a joint pipe as described above, one side of the pipe assembly is closed and the test water is supplied at a pressure of about 40 bar from the other side, We are checking for leaks to the site.

However, in the above test, when the pressure of the test water can not be maintained, the high pressure pipe is expanded and deformed to swell or bend, so that the test is performed in a condition that the condition of the watertight test is not satisfied sufficiently. It becomes inaccurate. There is a problem that the reliability of the test result can not be increased accordingly.

The present invention relates to a pipe assembly for preventing a pipe assembly from being inflated and deformed by a pressure applied during a watertightness test by visually confirming whether or not leakage of a connection portion between a high-pressure pipe and a joint pipe, And an object of the present invention is to provide a watertightness testing apparatus having an expansion deformation preventing function.

According to an aspect of the present invention, there is provided a pipe assembly comprising: a fixed block having a hollow structure to surround the entire periphery of a pipe assembly and spaced apart from each other along a longitudinal direction of the pipe assembly; A groove formed on the surface of the fixed block contacting with the pipe assembly so as to be filled with the test water to be leaked; A connecting member connecting between the fixed blocks; And the watertightness test equipment having the expansion deformation preventing function of the pipe assembly including the watertight test equipment.

Also, in the present invention, the fixing block may have a structure in which a discharge hole is formed in the fixed block so that the leaked test water can be discharged to the outside.

As described above, when the watertightness testing apparatus having the function of preventing the expansion deformation of the pipe assembly according to the present invention is used, it is possible to visually check the leakage and the degree of leakage of the connection portion connected between the high-pressure pipe and the joint pipe And it is also possible to prevent the pipe assembly from being expanded and deformed by the pressure applied in the watertightness test.

Further, by the above-described effects, it is expected that the efficiency of the test can be improved and the reliability of the watertight work can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a watertightness testing apparatus having a function of preventing expansion deformation of a pipe assembly according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the configuration of the watertightness testing apparatus having the expansion deformation preventing function of the pipe assembly will first be schematically described.

The watertightness test equipment 10 according to the present invention includes a fixed block 14 having a hollow structure to completely surround the pipe assembly 12 and spaced apart along the longitudinal direction of the pipe assembly 12, A groove 16 formed in a wave form on the surface of the fixed block 14 to be brought into contact with the pipe assembly 12 and a connecting member 18 connecting the fixed block 14 to each other.

Specifically, the fixing block 14 and the connecting member 18 are made of a steel material, and a groove 16 is formed on the surface facing the pipe assembly 12 to receive water to be leaked. The fixed block 14 is formed with a discharge hole 20 communicating with the groove 16.

[Water tightness test]

Pressure pipe 12a and a pipe assembly 12b to which a pipe 12b is connected is inserted into a watertightness testing apparatus 10 having a hollow structure. And the welding portion of the high-pressure pipe 12a is positioned in the groove portion 16 of the fixed block 14. [

When the watertightness test is performed on the pipe assembly 12 in the above state, the pipe assembly 12 is connected to the test water supply device P through the test water supply device P at a pressure of about 40 bar on the other side of the pipe assembly 12, (T) to the inside of the pipe assembly (12) to inspect the leakage of the connection portion between the high pressure pipe (12a) and the joint pipe (12b).

For example, when leakage occurs on the connection portion between the high-pressure pipe 12a and the joint pipe 12b, the leaked test water T is filled with the groove portion 16 of the fixed block 14, The test water T filled in the groove 16 is discharged to the outside through the discharge hole 20 connected to the groove 16.

As described above, it is possible to easily visually check the degree of leakage as well as whether or not the leakage of the test water T is possible depending on whether the test water T is discharged or discharged or discharged.

When the pipe assembly 12 is unable to withstand the pressure of 40 bar, a deformation that tends to swell due to expansion tends to occur.

At this time, the both-side support securing portion 22 of the securing block 14 is firmly held in contact with the circumferential surface of the pipe assembly 12 with the groove portion 16 as a center, and the adjacent securing block 14 Are also strongly connected to each other through the connecting member 18 made of steel, so that the expansion of the pipe assembly 12 is suppressed to prevent the pipe from being deformed.

Therefore, through the use of the water-tightness testing apparatus 10 according to the present invention, the test is performed in a condition satisfying the condition for the water-tightness test, so that the reliability of the test result can be further improved together with accurate judgment of the leakage.

As described above, although the present invention has been described with reference to specific embodiments and drawings, it is to be understood that the present invention is not limited thereto and that various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. And various modifications and variations are possible within the scope of the claims of utility model registration claims.
