ERW pipe/seamless pipe hydrostatic testing machine is used to test the pressure of ERW pipe or seamless steel pipe. Large gap sealing mode is used, and generally, the pressure is 70Mpa, and the high pressure can be up to 130Mpa. The hydrostatic testing machine is equipped with comprehensive safety protection facilities to ensure personnel safety. It is equipped with the functions of computer recording, storing, printing and test results. It has the advantages such as high efficiency, simple operation, convenient maintenance, high test pressure, long service life of the sealing ring and strong safety.
The diameter range of hydrostatic testing machine is Φ20-Φ711mm, and the test pressure is as high as 130MPa.
