12Bar Hydrostatic Pipe Pressure Testing Machine

Because both pressure and temperature lead to a decrease in Yield strength of the material. However a hydro test can only recreate the pressure and not the temperature, so in order to compensate for the stress due to temperature, an additional pressure effect is added.The minimum hydrotest pressure for oil and gas lines is given in Tables 11.2 and 11.3, respectively, and is equal to 1.25 times the design pressure for pipelines.Pressure tests are carried out to induce a pre-determined stress level in a sample, by pressurizing the equipment and observing the results. The test is carried out by increasing the internal pressure, and creating a pressure differential with ambient pressure.
