AT470 Plastic Pipe Hydrostatic Pressure Tester is mainly used to determine the time-to-failure of plastic pipes under constant internal pressure and also the resistance to hydrostatic pressure in a short time period. This instrument complies with the following international and industry standards. ISO: ISO 1167, ISO 9080, ISO 1756. ASTM: ASTM D1598, ASTM F1335. CJ/T: CJ/T 108. GB/T: GB/T 15560. The main machine consists of a pressure control unit, magnetic valve, sensor, pressure workstation, etc. The number of working positions can be customized according to requirements, that is to say, the pressure interface can be customized such as 3, 6 or 10. The dimension of the test tank needed is based on the dimension of the test pipes. Refrigerating system is optional. The test tank can be connected with a refrigerating machine to perform low-temperature tests, thus the test temperature can be RT-95℃ or 15~95℃. Stainless end closures of different diameters can be selected according to customers’ requirements, the material is stainless steel or carbon steel.
