Selection of isolation valves for liquid hydrocarbon spheres
Thread Content
This post was last edited by ysk121115 on 2016-7-4 at 10:14. Is there any **standard** for the selection of cut-off valves for liquid hydrocarbon spheres, similar to HG/T or GB? If so, please recommend the names and numbers; it would be great if I could download them as well. Thank you very much! ! ! Additionally: For the ball tanks used for propane and liquefied gas, the diameter of the shut-off valves is between 250 and 300, with a pressure of around 3.0 MPa. Can only ball valves be used as shut-off valves in this case, or can parallel double-disc valves be utilized instead?
I really haven’t seen any specific selection criteria for liquefied hydrocarbon isolation valves; I’ll study it later!
Request a specification! ! ! Some of you kids, please help a lot. Thank you! ! !
