Corrosive media need what material hose transport

For the transportation of corrosive media, commonly used materials include the following:

 
1. Polytetrafluoroethylene (PTFE):PTFE has corrosion resistance and can resist the erosion of various strong acids, alkalis and organic solvents. It is a very common corrosive medium conveying hose material. PTFE hose also has excellent high temperature resistance and low coefficient of friction, and can work in the temperature range of -70°C to 260°C.

2. Fluorine rubber (FKM):FKM has excellent corrosion resistance and can resist the erosion of a variety of organic solvents, acids, alkalis and oxidants. It is a commonly used hose material for conveying corrosive media. FKM hose also has excellent high temperature resistance and works in the temperature range of -40°C to 200°C.
 
3. Chloroprene rubber (CR):CR has good acid and alkali resistance and can resist the erosion of some weak acids and weak bases. It is a commonly used medium conveying hose material. CR hose also has good wear resistance and oil resistance, and works in the temperature range of -40°C to 100°C.
 
4. Fluorinated polymers (FEP, PFA):FEP and PFA have good corrosion resistance and can resist the erosion of various acids, alkalis and organic solvents. They are a commonly used hose material for conveying corrosive media. FEP and PFA hoses also have excellent high temperature resistance and work in the temperature range of -20°C to 200°C.
 
It should be noted that the nature and concentration of different corrosive media are different, so when selecting the hose material, it is necessary to make a reasonable choice according to the corrosion performance, temperature range and pressure requirements of the specific medium. In addition, when using hoses to transport corrosive media, it is also necessary to pay attention to the installation and maintenance of the hose to maintain the integrity and reliability of the hose to ensure safe transportation.
