Pipe hydrostatic testing machine is used to test thermoplastic pipe, composite pipe (such as PP-RPP-B, PPA, PE, PE-X, PVCPVC-UPVc-c and aluminum-plastic composite pipe and other pipes) in the long time constant internal pressure and constant temperature under the pressure failure time or the maximum pressure value of instantaneous blasting. It is a necessary testing equipment for plastic pipe manufacturers and testing organizations.
