Plate Heat Exchanger plates are all stamped in one go using extremely precise dies. Only the plates formed in one go have the same precision, so there is uniform metal point contact between the plates and the plates to ensure that the plate heat exchanger can operate normally under higher pressure and withstand the pressure shock of the system.
Material Options
1, advanced stainless steel: excellent resistance to chloride pitting and crevice corrosion performance, so that the plate heat exchanger can not be used with 316 type of brine, inorganic acids and other media.
2, titanium: plate heat exchanger using non-alloyed titanium, it can naturally generate a passivated protective film, and if once destroyed, with "self-healing", so corrosion resistance than stainless steel is good, is suitable for chlorine-containing media typical materials.
3, titanium-palladium alloy: plate heat exchanger using the addition of palladium (0.12% to 0.25%) of non-alloyed titanium, which significantly improves the corrosion resistance of titanium in acid media.
Plate type selection
Plate type or corrugated type should be based on the actual needs of the heat transfer occasion. For the flow of large allowable pressure drop is small, should choose a small resistance plate type, and vice versa, choose a large resistance plate type. According to the fluid pressure and temperature, determine the choice of removable type, or brazed type. Determine the plate type should not choose a single plate area is too small plate, so as to avoid the number of too many plates, between the plate flow rate is small, the heat transfer coefficient is too low, the larger the heat exchanger should pay more attention to this issue.
