Hydrostatic test of oil casing is an essential link in the steel pipe manufacturing process and an important means to test the overall quality of oil steel pipes. In simple terms, it is a test in which the pipe is filled with water and tested under pressure to maintain the specified pressure without leakage or rupture. The oil casing hydraulic testing machine is used to test the bearing pressure of the casing, the test pressure is 70mpa, 9 5/8", 7", 5 1/2", 5", 4 1/2", 3 1/2 ", 2 7/8, etc. meet the different specifications of API spec 5ct casing. The pressurized cylinder is used for pressurization, the pressurization method is fast and reliable, and it is equipped with an automatic control system that can display the pressure curve in real time, output the test report, and save the test data.
