Dear colleagues, what material should be used for the gasket of the suction and discharge valves in reciprocating compressors?
Copper or aluminum gaskets work fine; you can choose whichever you prefer
Metal or asbestos gaskets will work; metal gaskets are preferable.
They are usually metal gaskets such as copper, aluminum, or soft iron gaskets
Under normal circumstances, aluminum or copper gaskets are used; if there are defects in the sealing surface, stainless steel gaskets can also be chosen.
Copper pads are better. . . . . . . . . . . .
Copper pads are generally used! ! ! ! ! ! ! ! ! ! !
The main materials used are L3-M, T3, and 00Cr13; the choice depends on the operating pressure – the first two materials are used for low pressures, while the latter two are used for high pressures.
Thank you! Copper gaskets do not perform very well and often get damaged. Stainless steel gaskets were used during that period; due to the long service life of the compressor, the cylinder sealing surfaces were not very smooth, which led to leakage in the compressor and suboptimal performance. The aluminum pad has not been tried yet. For a hydrogen compressor with an operating pressure of 6.0 MPa, is an aluminum gasket suitable?
Copper gaskets need to be annealed. “Copper gaskets do not perform very well and often get damaged. “How can a static seal get worn out?” ? ? ?
