종래 합성수지관은 수도관과 하수관 그리고 오수관, 우수관 등 다양한 종류의 관이 생산되고 있는 실정에 있으며, 이러한 다양한 종류의 관들은 일정한 길이(약 6미터 정도)로 절단하고 다양한 연결방법을 이용하여 연결한 후 지하에 매설하여 유체가 외부로 유출되지 않고 공급될 수 있도록 한다.Conventional synthetic resin pipe is a situation that a variety of pipes, such as water pipes, sewage pipes and sewage pipes, rainwater pipes are produced, these various types of pipes are cut to a certain length (about 6 meters) and connected using a variety of connection methods It is buried underground so that the fluid can be supplied without leaking to the outside.

종래의 합성수지관은 소정의 길이로 절단한 후 관의 양 선단에서 다양한 방법을 이용하여 엔드캡을 연결한 후, 한 부분에서 공압을 내부에 20∼40bar 정도로 공급하여 어느 정도의 내구성을 갖는지 실험하게 된다.The conventional synthetic resin pipe is cut to a predetermined length and then connected to the end caps by various methods at both ends of the pipe, and then experimented to see how durable it is by supplying about 20-40 bar of pneumatic pressure in one part. do.

그러나 합성수지관의 양 선단에서 밀봉하는 엔드캡은 낮은 공압을 공급하는 경우에는 별문제가 없지만 높은 공압을 공급하는 경우에는 합성수지관과의 밀봉이 제대로 이루어지지 않아서 공기가 외부로 새어나오게 되므로 내구성을 제대로 측정할 수 없게 되는 결점이 발생하게 된다.However, the end caps that are sealed at both ends of the resin tube have no problem when the low pneumatic pressure is supplied, but when the high pneumatic pressure is supplied, the air is leaked to the outside because the sealing is not properly performed, so the durability is properly measured The drawback is that it becomes impossible.

또한, 복잡한 밀봉구조를 통하여 공기가 합성수지관의 외부로 새어나오지 못하게 하지만, 매우 어려운 문제점으로 대두되고 있는 실정이다.In addition, although the air is not leaked to the outside of the synthetic resin pipe through a complicated sealing structure, it is a situation that has emerged as a very difficult problem.

따라서 본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 합성수지관의 양 선단을 안정되고 정확하게 밀봉하여 공기의 공급에 의한 내구성을 시험할 수 있도록 함을 목적으로 한다.Accordingly, the present invention has been made to solve such a conventional drawback, and aims to test the durability by supplying air by sealing both ends of the synthetic resin pipe stably and accurately.
