About check valve selection
Thread Content
The company has a long-distance pipeline, which is transported from the Yangtze River pier to the rear storage tank. It is about 1,200 meters long. The operating parameters are normal temperature, pressure 1.8MPa, and diameter DN150. It is installed at the entrance of the rear propylene storage tank. What kind of check valve should I choose?
Others should also be possible, such as butterfly ones, etc. It seems that the working conditions are not complicated: lol
Propylene is gaseous and toxic at room temperature. If there is no cold insulation measure, it is estimated that the flange gas check valve flange surface should use a concave surface (FMF).
It is liquid propylene at room temperature, because there is pressure! The flange must be MFM, and what I want is the check valve selection model.
It depends on whether it is installed on a horizontal pipe or a vertical pipe. The screw-up or lifting type can be used on the horizontal pipe, and the screw-on type can only be used on the vertical pipe.
