Problems solved by technology
[0002] It is known that centrifugally formed pipes require overall pressure testing, and plastic and composite material pipes have large deformations. If the overall pressure is tested, more water needs to be replenished during the pressure test. The deformation is large, and the ends of the pipe are not easy to seal
[0003] The existing metal pipe pressure test machine has a small water intake, which cannot meet the overall pressure test requirements of plastic and composite material pipes, especially large-diameter pipes
[0004] The pressure test of plastic pipe is mostly sampling pressure test, and the pressure test sample is short. In addition, the test pressure of large-diameter plastic pipe is relatively low. Therefore, the existing plastic pipe pressure test machine cannot meet the requirements of plastic and The overall pressure test requirements for composite pipes
[0005] Therefore, there is no pressure testing machine for the overall pressure test of plastic pipes at present.

Embodiment Construction
[0030] Relevant technical content and detailed description of the present invention, now cooperate accompanying drawing to explain as follows:
[0031] As shown in Fig. 1 and Fig. 2, a kind of pipe material pressure testing machine of the present invention comprises:
[0032] (1) Pipe support system:
[0033] The system consists of a column 1, a longitudinal beam 2, and a water tank 3. The columns 1 at both ends are connected with the longitudinal beam 2 and the water tank 3, so that the pressure of the pipes is self-balanced, and a huge supporting device is omitted.
[0034] (2) Pipe lifting and positioning system:
[0035] The system includes a guide mechanism 5 arranged on both sides of the jacking cylinder 4; a bracket 6 supported by the jacking cylinder 4; a stabilizing cylinder 7 arranged at the bottom of the bracket 6; arranged on the longitudinal beam 2 The limit switch 8 and the adjustment device and the relevant hydraulic drive system; the bottom of the stabilizing...

A tubing compression-testing machine includes: a tubing supporting system, a backing and location system, a compression-testing, sealing and compression-loading system, a water supplying system, a pressing system, a hydraulic station and a control cabin, which solves the problem of difficult compression test to integers of large diameter plastic tubing and tubing of complex materials to reduce the test cost.
Description
technical field [0001] The invention relates to a pressure test device for integral pipes, in particular to a pipe pressure test machine suitable for the integral pressure test of large-diameter plastic pipes and composite material pipes. Background technique [0002] It is known that centrifugally formed pipes require overall pressure testing, and plastic and composite material pipes have large deformations. If the overall pressure is tested, more water needs to be replenished during the pressure test. The deformation is large, and the two ends of the pipe are not easy to seal. [0003] The existing metal pipe pressure test machine has a small water intake, which cannot meet the overall pressure test requirements of plastic and composite material pipes, especially large-diameter pipes. [0004] The pressure test of plastic pipe is mostly sampling pressure test, and the pressure test sample is short. In addition, the test pressure of large-diameter plastic pipe is relativel...
