In-House Pressure Testing For Better Quality Control

Pressure tests are conducted to assess the safety, reliability, and leak tightness of pressure systems. A pressure test is almost always required for a new pressure system before use or an existing pressure system after repair or adjustment. There are two methods for pressure tests: hydrostatic and pneumatic.

A hydrostatic test is conducted by using water as the test medium, whereas a pneumatic test uses air, nitrogen, or any non-flammable and nontoxic gas. Pressure tests must always be performed under controlled conditions, following an approved test plan, and documented in a test record. A single approved test plan may be used for several similar tests, but a separate test record is required for each.

Quaker City Castings has established procedures and equipment for hydrostatically pressure testing castings up to 2,500 psi.
