Buy Top-of-the-Range Hydrostatic Pressure-Testing Equipment in Johannesburg


If you are looking for the right equipment for hydrostatic pressure testing, we have an impressive range of options to offer you at Bestline Manufacturing in Johannesburg. First, let us take a look at the process and what it entails. Hydrostatic pressure testing is a method of testing a vessel for leaks and weaknesses, and to verify performance and durability. The type of vessels that are usually tested may include pipelines, gas cylinders, fuel tanks, boilers, and plumbing systems. The method must involve a test medium, which can be air, oil, or water. In most instances, dyed water is used, as it is the most reliable and least expensive of the three options. Water is also chosen because the vessel is unlikely to expand too much under pressure and so the risk to the testing technician is smaller than in the case of air testing. If air testing is required, the test is usually done under water to ensure safety.

The process is a fairly straightforward one, in which hydrostatic pressure-testing equipment is used to exert pressure on the vessel. But first, the vessel is filled with the liquid medium and all the air inside is bled out. Pressure is then applied to the vessel. Pressure resistance can also be tested by closing the pressure valve and monitoring if the vessel loses pressure thereafter. Leaks can be visually confirmed with the leaking out of the dyed water. The overall strength of the vessel is determined by maximum pressure it can withstand before permanently deforming.

In most instances, these tests are carried out to ensure that vessels such as pipes, tanks, and so on are up to the safety standards imposed by industry. Durability and strength can dwindle over time, so the tests are usually repeated at various intervals during the lifespan of the vessel in question. It is advised that hydrostatic pressure-testing equipment is used to test the vessels pressure capacity up to 150% of its designed handling capacity. For instance, if a vessel has a 1000 psi pressure rating, then it should be tested to 1500 psi. Of course, using quality pressure-testing equipment is essential to the reliability and accuracy of the pressure test results and you can find top-of-the-range equipment right here at Bestline Manufacturing in Johannesburg.
