Question

Accepted Answer

Various pressure tests are conducted on valves including hydrostatic test, pneumatic test, and cryogenic test.

Hydrostatic test is conducted by filling the valve with water and pressurizing it to a specified pressure to check for leaks.
Pneumatic test involves using air or nitrogen to pressurize the valve and check for leaks or defects.
Cryogenic test is performed at low temperatures to ensure the valve can withstand extreme conditions.
Other tests may include high-pressure gas test, low-pressure gas test, and seat leakage test.

Accepted Answer

The type of pressure test carried out on valves are the backseat test, shell test, low-pressure closure test and high-pressure closure test.
