Ball Valve Material Selection in Basic Design
We are dealing with a crude oil terminal with maximum line pressure (operating) 2,5 bar. (crude density=930 kg/m3 and max H2S=70 ppm, design temp = 4-85 centigrade), The valves are 40” full bore ball valves .
I have 2 questions:
1- Which material is most suitable for the body, A105, A350 LF2 or A216 Gr. WCB? (Considering both technical and economical views according to the operational condition). Generally in which conditions the forged body is mandatory?
2- Which material is most suitable for the ball? Fully SS 304 or A350 LF2 with E.N.P 25 Micron?
Thanks all before
