We have a 6" carbon steel line which comes from "liquid Flash Drum" goes to "Vapour Recovery Unit". Maintaining minimum pressure drop along this line is critical for the VRU. So we are looking for a check valve with the lowest pressure drop in this line. I would put it in the 0.05 kPa area...
We were going to buy ball valves with A105+ENP for ball materials. one offered A105+NI60. Does any body knows the advantage or disadvantage of this kind of overlay? Thanks in advance.
We are buying LCC ball valves. One manufacture offered 4140+ENP for Ball & Stem. Our MDMT is -45C. Would you please advise if the offered material is suitable for low temperatures?
Thanks in advance.
