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...
we are designing a 600,000 bbl aboveground storage tank ring foundation with diameter 80 meters. according to settlement and also soil bearing calculations, the calculated width is 60 cm.
Also the elevation code of top of foundation is 91 meters and the outside area of tank (inside dike wall)...
To evaluate the cutting volume of existing ground to reach a flat surface with specified elevation We have point database includes 30 points X,Y, and Z gathered from existing ground.
Using Autodesk Land Desktop 2009, I have defined surface1 (associated to existing ground) with those 30 points...
Our company is EPC contractor for a crude oil transmission plant between storage tanks. Based on maximum liquid velocity limitation=2 m/s, the pipe size is 48” for the main lines from tanks to manifold.
now for sizing on/off motorized ball valves, could we use reduced bore ball valve instead of...
