Description

  The present invention relates to a piping workability evaluation test apparatus. More specifically, for example, the present invention relates to a pipe workability evaluation test apparatus that can be suitably used when performing an evaluation test on tightening workability of a gasket or the like in a joint portion of a pipe used in a petrochemical plant, a factory, or the like.

  In the field at a petrochemical plant, factory, etc., a plurality of pipes may be arranged in a complicated manner. When tightening pipe joints at such locations, other pipes may become obstructive, making it difficult for workers to perform joint tightening work or insufficient tightening force. The contents in the pipe may leak.

  Such workability at the site can be improved to some extent by a design drawing at the site. However, it is not easy to accurately determine whether the workability by the worker is sufficiently secured by using only the design drawings. Actual work is actually performed on the site that is simulated so as to approximate the work site. If this is not done, it is impossible to accurately determine whether workability is sufficiently secured.

  Conventionally, as an evaluation test device for simulating damages such as cracks occurring inside the water cooling holes formed inside the mold in the actual operating state, a test in which a stress concentration part is formed inside the water cooling holes An evaluation test apparatus comprising a body, a cooling water supply device for circulating a temperature-controlled cooling water through the water cooling hole of the test body, and a heating device for heating the test body from the outside is proposed. (For example, refer to Patent Document 1).

  However, as the applicant has investigated so far, the prior art describes a pipe workability evaluation test apparatus that can be used when performing an evaluation test of tightening workability of gaskets and the like at joints of pipes. No literature has been found.

  In this specification, “plumbing workability” includes both the meaning of whether piping work can be performed efficiently and whether piping work can be performed accurately. It is.

  Below, although the piping workability | operativity evaluation test apparatus of this invention is demonstrated based on drawing, this invention is not limited only to the embodiment as described in this drawing.

  FIG. 1 is a schematic front view showing an embodiment of the pipe workability evaluation test apparatus of the present invention. FIG. 2 is a schematic plan view showing one embodiment of the pipe workability evaluation test apparatus of the present invention.

  As shown in FIG. 2, the pipe workability evaluation test apparatus is disposed in a direction perpendicular to the evaluation target pipe 1 and in the vicinity of the evaluation target pipe 1 in the vertical direction. 1 and 2b for failure piping 2a, 2b. The pipe for evaluation 1 means a pipe used when performing piping work at an actual work site. Further, the trouble pipes 2a and 2b mean pipes that hinder the pipe work when the pipe work is performed at an actual work site.

  1 and 2 show an embodiment of the pipe workability evaluation test apparatus when two fault pipes 2a and 2b are provided. The number of fault pipes 2a and 2b is actually Since it is appropriate to adjust appropriately according to the work site, it is not always necessary to use two pipes, and the number of pipes that hinder the piping work when performing the piping work at the actual work site, for example, 1-5 may be sufficient. The failure pipes 2a and 2b are provided in the vicinity of the evaluation target pipe 1 in a direction perpendicular to the evaluation target pipe 1. The "near the evaluation target pipe 1" is a pipe work at an actual work site. This means that there is a gap between the piping that becomes an obstacle when performing the piping and the piping that is the target of the actual piping work. The positional relationship such as the distance between the evaluation target pipe 1 and the fault pipes 2a, 2b, the diameter of the evaluation target pipe 1 and the fault pipes 2a, 2b, etc. are also arbitrary and are used in actual work sites. It is preferable to adjust appropriately according to the piping that becomes an obstacle.

  The obstacle pipes 2a and 2b are attached to the vertical movement devices 3a and 3b, respectively. The vertical movement devices 3a and 3b are arranged in the vertical direction so that the obstacle pipes 2a and 2b can move in the vertical direction. The lengths of the vertical movement devices 3a and 3b are arbitrary, and are preferably set appropriately in consideration of the positions of the obstacle pipes 2a and 2b provided in the actual work site. For example, the failure pipes 2a and 2b can be attached to the vertical movement devices 3a and 3b by providing attachment portions (not shown) at both ends of the failure pipes 2a and 2b. The positions where the obstacle pipes 2a and 2b are attached to the vertical movement devices 3a and 3b are arbitrary, and are preferably adjusted as appropriate according to the actual work site. The upper ends of the vertical movement devices 3a and 3b may be in an open state, or a stopper may be provided to prevent the attachment portions provided in the obstacle pipes 2a and 2b from falling off. Further, the lower ends of the vertical movement devices 3a and 3b are provided with, for example, wheels and casters (not shown) in order to adjust the distance between the evaluation target pipe 1 and the obstacle pipes 2a and 2b. As shown in FIG. 4, the guide rails 4a and 4b arranged so as to be parallel to the evaluation target pipe 1 are arranged so as to be movable in parallel to the evaluation target pipe 1. It is preferable.

In the pipe for evaluation 1, when the object of the pipe workability evaluation test is tightening workability of a gasket or the like in the joint part of the pipe, the pipe 1 for evaluation includes, for example, the joint part 5 or the like. It can be arranged. When a gasket is used for the joint portion 5 of the pipe 1 for evaluation, whether or not the gasket can be easily attached at the joint portion 5 and an appropriate tightening force is applied to the gasket at the joint portion 5. It is possible to evaluate or test whether it can work. When an appropriate tightening force is not applied to the gasket, the contents of the evaluation target pipe 1 leak at the joint portion 5 of the evaluation target pipe 1. Whether the contents of the evaluation target pipe 1 leak at the joint portion 5 of the evaluation target pipe 1 is determined by, for example, setting the evaluation target pipe 1 to a closed system and increasing its internal pressure. It can be confirmed by checking whether or not the contents of the pipe for evaluation 1 are leaked at the joint portion 5 and measuring with a pressure gauge whether there is a decrease in the internal pressure of the pipe for evaluation 1. .

  Further, in the pipe workability evaluation test apparatus according to the present invention, the obstacle parallel pipe 6 may be disposed in parallel with the pipe 1 for evaluation. Thus, when the obstacle parallel pipe 6 is disposed in parallel with the evaluation target pipe 1, as described above, in a state that more closely approximates the actual piping work site, a gasket or the like in the joint portion 5 of the pipe Tightening workability can be evaluated and tested. In the embodiment of the pipe workability evaluation test apparatus shown in FIG. 2, four fault parallel pipes 6 are provided, but the number of fault parallel pipes 6 is appropriately adjusted according to the actual work site. Since it is appropriate to do, it does not necessarily have to be four, for example, 1 to 5 may be sufficient. Further, the positional relationship such as the interval between the evaluation target pipe 1 and the obstacle parallel pipe 6, the diameter of the obstacle parallel pipe 6, and the like are also arbitrary, and are preferably adjusted as appropriate according to the actual work site. Therefore, in order to install the obstacle parallel pipe 6 at an arbitrary position according to the actual work site, for example, an arbitrary pipe of the pipe workability evaluation test apparatus using a moving rail (not shown) or the like is used. It is preferable that it is movably arranged at the position.

  In the pipe workability evaluation test apparatus of the present invention, a walkway 7 may be disposed in the vicinity of the evaluation target pipe 1 in order to be adapted to an actual work site. When the corridor 7 is disposed in this way, an evaluation test such as a tightening workability of a gasket or the like in the joint portion 5 of the evaluation target pipe 1 is performed in a state more similar to an actual piping work site. Can do. The walkway 7 can also be used as a working scaffold in the piping work site. The walkway 7 may be provided so as to be movable on a moving rail 8 disposed so as to be parallel to the evaluation target pipe 1. In order to allow the walkway 7 to be easily moved on the moving rail 8, for example, wheels or casters (not shown) may be provided in the lower part of the walkway 7. In this way, when the moving rail 8 is disposed so as to be parallel to the evaluation target pipe 1 and the corridor 7 is provided on the moving rail 8, the corridor is located at the position in the actual piping work. 7 can be installed, so that it is possible to more accurately evaluate and test the tightening workability of a gasket or the like in the joint portion of the pipe.
