I am designing the piping system for my treater desanding system. the treater is operationg at about 80 psig and and i have 2" sch. 160 line coming out of treater going into an atmospheric tank.

We have been facing serious problems in two areas of our plant. One is in liquid HCL isolating valves, we have more than 50 valves on dry HCL service at very low temperature but every now and then, we

I am looking for the tests and inspection that are commonly specified when purchasing ball, gate, globe etc valves for any service (water, steam and other). Reviewing ANSI B16.34 it seems to require o

how does one work, where is it fitted etc? I am interested, and this will help me spec one when talking to the vendor.
