hydrostatic testing

Hydrostatic testing is a very important procedure that is used for checking the performance of pressure vessels. This testing is extremely important when testing is undertaken on vessel and applications like cylinders, boilers and hose testing, to test for flaws, leaks and any other issues that could result in leakage.

The procedure for hydrostatic testing is simple and easy, with incompressible fluids like oil and water used for the test. The vessel to be examined is filled with fluids that will then help to undertake the tests that will confirm the status of the hose. Sometimes, a red or fluorescent dye in liquid contained in the vessel. As a safety factor the pressure should be increased to an amount that is above the usual capacity, to ensure that the application will be safe should there be a rare change in pressure that could ultimately burst an insecure hose.

The sealed vessel, which is filled with incompressible fluid, will be subject to different pressures for set amounts of time. After a hydrostatic test has been completed, a physical and visual inspection will also take place, determining whether the device has been damaged or distorted due to the pressure it has been subjected to.

The pressure is usually 150% of the vessels recommended operating level which allows a thorough test of the vessel to be taken out. A faulty vessel supporting the process of an application is extremely important, as if there were any problems – leakages, outages and even fatalities can occur. Buckley Industrial can conduct a range of tests that will ensure that your applications and vessels are in full working order and safe to use. They specialise in the manufacturing, inspection and testing of flexible hose assemblies for the power generation, chemical, food processing, paper and petrochemical industries and can supply you with the services that you require.
