Plastic Pipe Hydrostatic Pressure Testing Machine uses compressed air as the power source, the output hydraulic pressure and drive air pressure is proportional to. By adjusting the pressure of the driving air supply, the corresponding hydraulic pressure can be obtained. According to the different pressure of the test piece, the computer inputs the experimental data to automatically adjust the driving gas pressure. The high-pressure pump generates high-pressure liquid, passes through the pressure control system and is sent to the sample piece by the high-pressure pipe for static pressure test and burst te
