Petrochemical producers and many other industries depend on pressure vessels to manufacture, transport, or store chemicals. Hydrostatic testing is a process used to verify the overall integrity of pressure vessels such as pipelines, plumbing, gas cylinders, boilers, and storage tanks. Hydrostatic testing is often used to qualify a piece of equipment that has been repaired or rebuilt, prior to it returning to service.
Hydrostatic testing begins with filling a component with liquid, often water, until the pressure reaches a specified level. An amount of pressure greater than the designed working pressure of the equipment is applied and held for a set timeframe, during which the equipment is examined for leaks. Specialized equipment is required to perform this type of testing.
