Answer 1

Explanation:

Reciprocating compressors are sensitive to dirt. Therefore the suction piping to each stage, from the knockout drum to the suction pulsation damper, should be “pickled” (chemically cleaned). Temporary strainers should be installed and left in place for several days during initial operation. These strainers are usually of the truncated cone or conical type and made of perforated steel plate with a double overlay of stainless steel wire mesh screen (often 100 mesh over 30 mesh). The screen is attached to the outside of the strainer basket so that the flow encounters the screen first. The strainer is typically located at the inlet to the suction pulsation damper.
