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...
Thanks all
According to B4-2-2 of Api 650 which I stated in the first topic, what is the meaning of “As a minimum, the bottom of the ringwall, if founded on soil, shall be located 0.6 m (2 ft) below the lowest adjacent finish grade”?
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...
Thanks for your contribution. The plant is designed base on ASME B31.3 and it is not a pipeline system, so no other rules of pigging is applied. we are not asked to design based on pigging probability, Each line starts from tanks, passing the roads using several elbows and ends to manifold with...
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...
