Description

[0001] PIPEWORK WORKABILITY EVALUATION AND TESTING DEVICE [0002]

The present invention relates to a piping workability evaluation test apparatus. More particularly, the present invention relates to a piping workability evaluation test apparatus which can be suitably used for evaluation test of, for example, fastening workability of a gasket or the like in a joint portion of a pipe used in a petrochemical plant, .

In the field of petrochemical plants, factories, etc., a plurality of pipes may be arranged in a complicated manner. When the pipe joint is fastened in such a place, it is difficult for the worker to perform the fastening work of the joint due to the obstruction of the other pipe, or the fastening force is insufficient so that the contents in the pipe from the joint portion of the pipe Leakage may occur.

Such workability in the field can be improved to some extent by the design drawings of the work site. However, it is not easy to accurately determine whether or not the workability by the worker is sufficiently secured with the design drawing alone. If the work is not actually performed on the site simulated to approximate the work site, It can not be accurately determined whether or not it is sufficiently secured.

The present invention relates to an evaluation test apparatus for carrying out a damage test such as cracking occurring in the inside of a mold formed inside a mold in an actual operating state by using a test specimen in which a stress concentration portion is formed inside the specimen, There has been proposed an evaluation test apparatus comprising a cooling water supply device for circulating a temperature-controlled cooling water to a water level and a heating device for heating the test subject from the outside (see, for example, Patent Document 1).

However, no prior art document describing a piping workability evaluation test apparatus which can be used when evaluating the fastening workability of a gasket or the like in a joint portion of a pipe has been found so far by the present applicant.

The piping for evaluation 1 means a piping used for piping work in an actual work site or a piping of the same kind as the piping. Also, the failure pipes 2a and 2b refer to pipes which are obstacles to the piping operation when the piping operation is performed in an actual work site, or pipings of the same kind as the piping.

Fig. 1 and Fig. 2 show an embodiment of the piping workability evaluation test apparatus when two failure piping 2a, 2b are formed. Since it is appropriate to adjust the number of the failure piping 2a, 2b appropriately according to the actual work site, there is no need to necessarily provide two, and the number of the failure pipes 2a, The number of piping, for example, 1 to 5, may be used. The disturbance pipes 2a and 2b are formed in the vicinity of the pipe 1 to be evaluated in the direction perpendicular to the pipe 1 to be evaluated but the "vicinity of the pipe 1 to be evaluated" Means that the piping is disturbed when the piping operation is carried out at the work site of the pipeline. The positional relationship such as the distance between the evaluation target pipe 1 and the failure pipes 2a and 2b and the diameter of the evaluation target pipe 1 and the failure pipes 2a and 2b are also arbitrary, It is preferable to adjust it appropriately according to the piping used in the piping, the piping to be an obstacle, and the like.

The positions where the failure pipes 2a and 2b are mounted on the up-and-down moving devices 3a and 3b are arbitrary, and it is preferable to adjust them appropriately according to actual operation sites. The upper ends of the vertically moving devices 3a and 3b may be in an open state or stoppers may be formed in order to prevent the mounting portions formed in the failure pipes 2a and 2b from coming off. The lower ends of the vertically moving devices 3a and 3b are provided with a wheel or a caster (not shown) or the like for adjusting the distance between the evaluation target pipe 1 and the failure pipes 2a and 2b As shown in Fig. 2, is formed so as to be movable in the parallel direction with respect to the pipe 1 to be evaluated on the guide rails 4a and 4b formed so as to be parallel with the pipe 1 to be evaluated .

The piping 1 to be evaluated is preferably the same as the piping used at the actual work site from the viewpoint of properly evaluating and testing the fastening workability of the gasket or the like in the joint portion of the piping actually used . When the subject of the evaluation test of piping workability in the evaluation object piping 1 is a fastening operation such as a gasket in the joint portion of the piping, the evaluation piping 1 is provided with, for example, (5) and the like can be arranged. When a gasket is used for the joint portion 5 of the pipe 1 to be evaluated, it is necessary to determine whether or not the gasket can be easily mounted on the joint portion 5 and whether or not the appropriate fastening force Whether or not it is possible to work on the gasket, or the like. In addition, when the proper fastening force is not applied to the gasket, leakage of the contents of the pipe 1 to be evaluated occurs at the joint portion 5 of the pipe 1 to be evaluated. Whether or not the leakage of the contents of the pipe 1 to be evaluated occurs in the joint portion 5 of the pipe 1 to be evaluated can be determined by taking the pipe 1 to be evaluated as a closed system, It is possible to check whether or not the leakage of the contents of the pipe 1 to be evaluated has occurred in the joint portion 5 of the pipe 1 to be evaluated or to decrease the internal pressure of the pipe 1 to be evaluated By measuring with a pressure gauge.

In the piping workability evaluation test apparatus of the present invention, the obstacle parallel piping 6 may be arranged in parallel with the piping 1 to be evaluated. As described above, when the obstacle parallel pipe 6 is disposed in parallel with the pipe 1 to be evaluated in this way, the joint portion 5 of the pipe is provided with the obstacle- It is possible to evaluate the fastening workability of the gasket and the like in the test. In the embodiment of the piping workability evaluation test apparatus shown in Fig. 2, four parallel piping 6 for failure are formed, but it is preferable that the number of parallel piping 6 for the damages is appropriately adjusted according to the actual work site It is not necessary to necessarily set four, and for example, it may be one to five. The positional relationship such as the distance between the evaluation object pipe 1 and the obstacle parallel pipe 6, the diameter of the obstacle parallel pipe 6, etc. are arbitrary, and it is preferable to adjust them appropriately according to the actual operation site . Therefore, the parallel piping 6 for the failure can be moved to any position of the apparatus for evaluating piping workability evaluation, for example, by using a movable rail (not shown) or the like, It is preferable that they are arranged in such a manner that they can be arranged.

In the piping workability evaluation test apparatus of the present invention, the bore 7 may be disposed in the vicinity of the pipeline 1 to be evaluated so as to fit the actual work site. In the case where the bores 7 are arranged in this way, the joint performance of the gasket or the like in the joint portion 5 of the pipe 1 to be evaluated is evaluated Can be tested. The bore (7) may also be used as a work footpath at the piping work site. The boll 7 may be formed so as to be movable on a movable rail 8 arranged so as to be in parallel with the pipe 1 to be evaluated. For example, a wheel or a caster (not shown) may be formed on the lower portion of the bore 7 in order to make the bore 7 readily movable on the movable rail 8. [ When the moving rail 8 is arranged so as to be in parallel with the pipe 1 to be evaluated and the bore 7 is formed on the moving rail 8 as described above, It is possible to more accurately evaluate the fastening workability and the like of the gasket and the like in the joint portion of the pipe.

In the piping workability evaluation test apparatus according to the present invention, a chief section 9 may be formed if necessary. The patriarchy 9 can be used as a scaffold or the like when an operator moves to a work place. The chief 9 may be movable, fixed, or may be easily adjustable in height.

Further, in the piping workability evaluation test apparatus of the present invention, the side columns 10 may be formed as necessary. The piping for evaluation 1 and the piping for damages 2a and 2b to be evaluated are arranged in such a manner that a suspension cradle 11 is disposed on the side plate 10 and a crane , The parallel piping (6) for failure and the like can be facilitated.

A schematic front view of another embodiment of the piping workability evaluation test apparatus of the present invention is shown in Fig. In the piping workability evaluation test apparatus of the present invention shown in Fig. 3, a piping (not shown) for evaluation and piping pipes 2a and 2b for evaluation are disposed on the suspension carriage 11. The suspension cradle 11 is connected to one end of the rotary shaft 12 through a connection port 14. The rotary shaft 12 is mounted so as to freely rotate on its side. At the other end of the rotary shaft 12, a handle 13 for rotating the rotary shaft 12 is disposed.

In the piping workability evaluation testing apparatus shown in Fig. 3, since the suspension cradle 11 can be appropriately inclined at a predetermined angle by rotating the handle 13, the piping for evaluation and the piping for failure 2a and 2b It is possible to evaluate the fastening workability and the like of the gasket in the joint portion of the pipe in a state close to the actual piping work site since the height from the ground can be easily paralleled.

In the piping workability evaluation test apparatus of the present invention, for example, when the joint portion 5 is mounted on the piping 1 for evaluation, the piping for damage 2a, 2b interferes with the installation work It is difficult to determine whether or not the worker will be difficult to perform the clamping operation or the clamping force in the joint portion 5 is insufficient to cause the pipe 1 to be evaluated from the joint portion 5 of the pipe 1 to be evaluated, Whether or not the contents of the product may be leaked or may be evaluated.

Therefore, the height and position of the obstacle pipes 2a and 2b, the distance between the evaluation object pipe 1 and the obstacle pipes 2a and 2b, and the like are measured using the apparatus for evaluating the piping workability evaluation of the present invention It is possible to reproduce a situation in which it is difficult to tighten the gasket or the like in the joint portion 5 of the pipe so as to closely match the actual piping work site. Thus, without depending on the design drawings of the work site, for example, , The joint workability of the gasket in the joint portion of the piping used in the petrochemical plant, the factory, etc. can be accurately evaluated and tested.
