All About Hydrostatic Pressure Testing Equipment
Hydrostatic pressure (HPS) refers to the pressure exerted on an instrument from a liquid at a pressure greater than atmospheric pressure. Hydrostatic tests are conducted on many hydrostatic equipment to assess the resistance of fluids against pressurized changes in elevation and weight. These tests are performed in many different applications, such as vessel testing, vessel fittings testing, vessel pump testing, pipe freezing, gas testing and oil testing. There are many other types of hydrostatic tests, too many in fact to mention, that hydrostatic equipment has been designed to perform. Below we discuss some of these other types of hydrostatic testing.
A number of different materials can be hydrostatically tested using hydrostatic pressure testing equipment. These include but are not limited to: polyvinyl chloride (PVC), polystyrene, polycarbonate, polyurethane, stainless steel, zinc coating, Teflon coated materials, etc. The equipment used for hydrostatic pressure testing equipment testing has changed quite a bit over the years, as you can see from the list above.
If you have any questions about using a hydrostatic pressure testing machine, there are quite a few companies who will be more than happy to answer your queries. Many times, you might need to rent your equipment before you can begin testing. In this case, the company you contact will be able to give you more information. For those of you renting equipment, some companies may even offer you a rental support or warranty with your purchase of hydrostatic pipe machines.
Some hydrostatic pressure testing machine rental companies will allow you to test equipment at their labs or showrooms, although you won’t be able to take actual possession of the machinery. Others will let you test equipment on a temporary basis, such as a couple of hours. The best thing you can do when trying out rental companies is to ask for a sample, so that you can return it with the proper equipment. This will help you make sure that the test was completed correctly.
A good hydrostatic pressure testing machine should offer you accurate measurements. You don’t want measurements to be off by just a little bit, so make sure that the measuring equipment is capable of taking the full range of measurements that are necessary. Don’t assume that the range is the same for every test. There are many variables that could skew the results, and an accurate reading will be necessary. When renting equipment, it’s best to get something that will give you an average result when you compare it with other instruments.
To prevent damage to your pipeline, it’s important that the hydrostatic pressure testing equipment vessels are large enough to allow you to easily control the flow through the pipes. These vessels can either be very large or very small, but all of them should be placed on the ground, flat, with no obstructions in place. This is very important, especially if the flow is supposed to travel along the pipelines underground. There is a lot of risk when trying to set up or break down underground pipelines. Make sure that any pipes being tested are protected, and try to work as quickly as possible to avoid any damage.
