API 5CT Hydrostatic Test Of Oil Casing
The hydrostatic test of API 5CT oil casing is to test the pipe under a specified pressure when it is filled with water to see whether leakage or rupture will occur. It is used to detect the leakage resistance of the steel pipe under standard test pressure and pressure stabilization time. It is a steel pipe An integral part of the manufacturing process. The operation includes three steps: flushing, pressure testing, and water control. Today, we will introduce in detail the hydrostatic test of API 5CT oil casing.
