Pipe Valves

First of all, during the pressure test, the sealing device of pipe hydrostatic testing machine right through the end of the test tube is sealed at both ends. This is a key point we should focus on. And low pressure water injection, through the exhaust valve and air in the pipe, should filled with water with low pressure. With increasing pressure device to inject high pressure water pipe pressurized until the required test pressure, we will stop the test and check out the result.

At the same time, checking is also a necessary step. if the pipe is no leakage in the pressure test, deformation phenomena, proceed relief. Then open ends of the sealing device, the discharge pressure water pipe will be tested to the examination table visually inspected for suspicious penetration.
