Hydrostatic Pressure Test Method and Apparatus

A method of pressure testing a closed hydraulic system for leaks includes heating or cooling pressure intensification fluid before it enters the closed hydraulic system under pressure. The closed hydraulic system may be for example a blowout preventer for an oil/gas well, a manifold system or tubula...

Zusammenfassung:	A method of pressure testing a closed hydraulic system for leaks includes heating or cooling pressure intensification fluid before it enters the closed hydraulic system under pressure. The closed hydraulic system may be for example a blowout preventer for an oil/gas well, a manifold system or tubulars. The intensification fluid is heated or cooled to a temperature at or near the temperature of the fluid within the closed hydraulic system.
