Hydrostatic shell testing

Many times a client of ours will ask us to do additional testing to the valve/s before they purchase. One of the tests that is asked for is called hydrostatic shell testing and because we have our certification for API 6D such a test like this is no problem at all. Hydrostatic shell testing means that the shell, or the body of the valve will go through a pressure test. All valves MUST be hydrostatic ( WATER) shell tested to verify the valve can handle the maximum pressure it was built and designed for.  What you see in the video below is a hydrostatic test pressure, usually 1½ times the rated working pressure is applied to an assembled valve to verify the structural integrity of the pressure containing parts. Pipeline valves commonly go through these types of tests to ensure there are no leaks. Check out our Youtube page and you will see one of our API 6D, Trunnion ball valves going though the hydrostatic test and the test will continue for 4 hours. We stride for customer satisfaction and do not have any complaints. Contact us for more info www.gvcintl.com

 

The Through Conduit Gate Valve

One of our newest valves on the market is the Through conduit gate valve. Sometimes also referred to as Thru conduit. It is used for pipe pigging, but can be found more in “pipelines of subterranean heat steam, petroleum, natural gas production, transmission, and storage” The GVC Thru conduit gate valve is API 6D certified and has Double Block and Bleed capabilities. We offer these valves in 2” all the way through 36”. Many companies in the petrochemical industry prefer to use the Thru conduit gate valves as the valves are more suitable to corrosive fluids versus their ball valve counterpart. This valve is great for long distance transportation service of crude oil and natural gas.
