Determining the burst resistance or leak tightness of a fluid component or system by imposing internal pressure.
Important operation used to determine the suitability of a vessel or motor chamber for pressure containment. Done with water-filled units taken to high pressures with small hand piston pumps (system is aerated prior to test) under appropriate safety conditions.
A pressure test in which a valve is tested with water to detect leaks - may be a shell test or a seat closure test.
Test using noncompressible liquid under pressure at a level equal to or greater than the maximum pressure that will be utilized when in use, such as in steam boilers.
A test where a specific water pressure produces a stress to a percentage of the minimum yield strength in the material. It is applied internally to the full length of pipe to be sure it is free from leaks and capable of withstanding a specific pressure.
A strength test of equipment (pipe) in which the item is filled with liquid, subjected to suitable pressure, and then shut in, and the pressure monitored. Also a test to determine whether a container will hold a certain pressure.
pressure test in which the tank is filled with water instead of air and raised to five thirds the maximum working pressure, causing the water to expand and be displaced.
A vessel, pipe spool or piping system is completely filled with water and subjected to a test pressure which is equal to 1.5 times the design pressure.
Test in which pressure vessels are subjected to 150% of the design pressure.
A container test required at definite intervals by DOT to determine the wall thickness via measuring elastic expansion. Purpose of the test is to assure the container is safe for continued use.
A test conducted with either air, water or other fluids at a given value over design pressure, to prove the structural integrity of a pressure vessel.
To apply hydraulic pressure (usually with water) in order to find leaks in tubing, lines, piping, vessels and equipment.
A pressure test procedure in which a vessel or system is filled with water, purged of air, sealed, subjected to water pressure, and then observed and/or tested for leaks, distortions, and/or mechanical failure.
A pressure test by water at room temperature applied to a boiler to determine its safety, as a check on repairs or to trace suspected leakage.
Test using noncompressible liquid under pressure. Test pressure is equal to or greater than the maximum operating pressure that will be utilized when in use, depending on specifications of requirements. Codes often require that a hydrostatic test be done at 1 1/2 times the normal operating pressure of the particular system, to guarantee that the system is leak-tight and safe. While some systems are only tested before the first operation, systems such as steam boilers are tested periodically to guarantee that no deterioration has occurred during use.
A hydrostatic test is the normal way in which a gas pressure vessel such as a gas cylinder or a boiler is checked for leaks or flaws. Testing is very important because such containers can explode if they fail when containing compressed gas. Hydrostatic testing is also a way in which leaks can be found in lower pressure vessels such as pipelines and plumbing.
