Sealed vessel pressure testing method - by introducing virtually incompressible fluid into enclosure at pressure different to filling pressure

摘要

Into the enclosure a virtually noncompressible liq. is introduced. The liq. is introduced at a set filling pressure until the enclosure is full of the test liq. The filling pressure is not the same value as the test pressure. When the test pressure is less than the filling pressure fluid inside the enclosure is drawn off until the filling pressure equals the test pressure. When the test pressure is greater than the filling pressure a virtually noncompressible fluid is introduced into the enclosure after filling. The noncompressible fluid is introduced until the pressure in the enclosure reaches the test pressure. The noncompressible fluid introduced at a pressure greater than the filling pressure is the test liq. This fluid may be oil or water etc.
