Water-coated plastic composite pipe pressure testing machine
1 Introduction
The steel pipe pressure testing machine is used for detecting whether the coated steel pipe with a nominal diameter of not more than DN1200 has cracks and peeling in the inner coating of the pipe after being crushed. The length of the tested pipe sample is about 50mm. For the polyethylene coating, the distance between the two press plates of the test machine is 2/3 of the outer diameter. For the epoxy resin coating, the distance between the test plates is 4 /5.
