Principle of Hydrostatic Pressure Test of Casing Pipe

The compressibility of the water is very small, the tube is filled with water to pressurize the water, the volume is compressed, and the pressure rises; when the amount of compression is small, the pressure can rise to a very high value, which can be controlled by the instrument’s pressurization control Pressure rise-pressure maintenance, holding time-release pressure, complete a hydrostatic pressure test, the main purpose is to test whether the pipeline will leak during the pressure maintenance period, and test whether the product is qualified.

Some manufacturers conduct static pressure testing on the pipes one by one when the casing pipe leaves the factory, as a quality inspection process at the factory.
