Hydrostatic testing pumps


Hydrostatic testing pumps are commonly used to verify the integrity of fluid pressure vessels, such as cylinders, boilers, tubes, pipes, valves, castings, and other components. This procedure ensures that pressure vessels do not leak and are free of manufacturing defects. Hydrostatic testing is essential for the safety and durability of pressure vessels under operating conditions.
In this process, the pressure vessel to be tested is placed inside a sealed container filled with an incompressible fluid, typically water or oil. The vessel is then subjected to a known internal pressure, usually significantly higher than its maximum operating pressure (typically 150%), for a specified duration. The applied pressure causes the vessel to expand, and pre-installed instrumentation is used to measure the total and permanent expansion of the vessel. A physical and visual inspection follows to ensure the vessel has not been damaged or permanently distorted by the test pressure.
To re-verify the integrity of pressure vessels, a proof-pressure test, also known as a “modified hydrostatic test,” can be performed. The vessel is subjected to a known pressure for a set period, and during and after the test, it is inspected for any signs of abnormal distortion or failure.
