Plate Heat Exchanger Gasket Selection
According to the heat exchange medium flow form , the phe can be divided into single-sided flow and cross flow. Then the gaskets are divided into two forms as above.First, the single-sided flow means that the inlet and outlet of the same heat exchange medium is in the same plate side.Second, The cross flow means that the inlet and outlet of same heat exchange medium is in the different plate side( from the right (left) corner hole and flows out from the left (right) corner hole).
Nitrile rubber has excellent resistance to fuel oil and aromatic solvents, but it is not resistant to ketones, esters and hydrogen chloride. Therefore, it is resistant to oil-sealed products.
The main chain of EPDM rubber is a fully saturated linear structure containing no double bonds, and its side chain has a diene ruthenium, which can be vulcanized by sulfur. EPDM rubber has excellent aging resistance, ozone resistance, weather resistance, heat resistance (long-term use in 120 ° C environment), chemical resistance (such as alcohol, acid, alkali, oxidant), but not Resistant to aliphatic and aromatic solvents
