Let Hydrostatic Pressure Testing Find Out - Can it Take the Pressure?

Hydrostatic Pressure Testing is a nondestructive testing (Ndt) formula of finding leaks or verifying performance and endurance in pressure vessels such as pipe, tubing, and coils. Although this is thought about nondestructive testing and failures are rare, they can occur when the test piece does not meet performance or endurance specifications and may render the piece unusable.

Hydrostatic Pressure Testing normally entails filling the pipe, tubing, or coil with liquid, bleeding out air, pressurizing the piece, and then examining it for leaks or permanent changes in shape. A nearly incompressible (compressible only by weight, not air pressure) liquid, normally water or oil, is used to fill the test piece because it will only develop by a very small number if the piece fails, and therefore, minimizes the opening of injury or supplementary damage. Hydrostatic pressure testing also can be performed with pressurized air, but is commonly completed with the vessel under water for protection reasons. Although a testing laboratory may be adequate to perform hydrostatic pressure testing with water, oil, or air under water, water is the most commonly used test medium because it is less costly than oil and easier to set up than air under water.

3000 Psi

This nondestructive testing formula is used to test tubing, pipe and coils to pressures measured in Psi (e.g. To 10,000 Psi). The number of pressure used in hydrostatic pressure testing is all the time considerably more than the operating pressure, or the pressure the vessel will be subjected to in the policy of operation, to give the buyer a margin for safety. Typically the test is performed at 150 percent of the manufacture or working pressure. For example, if a pipe was rated to a working pressure of 2000 Psi, it would be tested at 3000 Psi.
