Heat exchange plate, heat exchanger frame, heat exchanger interface materials and their main application conditions
Heat exchanger plate material and main application conditions, what is the general material of the heat exchanger frame, and what is the heat exchanger interface material? The following are the plate materials and main application conditions:
1. Stainless steel heat exchanger plates are mainly used in clean water, river water, edible oil, minerals and other premises;
2. Titanium and titanium-palladium heat exchanger plates are mainly used in the premise of dilute sulfuric acid and inorganic aqueous solutions;
3. Nickel heat exchanger plates are mainly used in the premise of high temperature and high concentration of caustic soda;
4. Hastelloy heat exchanger plates are mainly used in the premise of concentrated sulfuric acid and inorganic aqueous solution;
5. Molybdenum heat exchanger plates are mainly used in the premise of dilute sulfuric acid and inorganic aqueous solution;
6. Graphite heat exchanger plates are mainly used in hydrochloric acid, medium concentration sulfuric acid, phosphoric acid, hydrofluoric acid and other premises;
Interface material of plate heat exchanger:
1. The standard interface material is stainless steel bushing;
2. Special interface materials, such as nitrile rubber, EPDM, Hastelloy, titanium and other alloys.
The material of the frame plate of the plate heat exchanger:
1. The standard frame plate material is generally carbon steel;
2. The special frame plate material is semi-stainless steel or all stainless steel.
When selecting plate heat exchanger plates, pay attention to the above points and choose suitable materials.
