Eng nge corrosion ofbutterfly valve te pawh a awm?

Butterfly valve-a corrosion hi chemical emaw electrochemical environment hnathawh avanga valve-a metal material tihchhiat tihna a ni tlangpui. “Corrosion” phenomenon hi metal leh a chhehvel boruak inzawmna (spontaneous interaction) atanga lo awm a nih avangin, a chhehvel atanga metal chu engtin nge kan inthen ang tih emaw, non-metallic synthetic material tam zawk hman dan tur emaw hi corrosion venna atana ngaih pawimawh ber a ni. A taksa chu abutterfly valve a ni(valve cover pawh tel) hian valve rit zawng tam zawk a luah a, medium nen a inzawm fo avangin butterfly valve hi body material atanga thlan a ni fo thin.

Valve body corrosion of chi hnih chauh a awmbutterfly valve te pawh a awm, chu chu chemical corrosion leh electrochemical corrosion te an ni. A corrosion rate hi a temperature, pressure, chemical property te, leh valve body material a corrosion resistance te atanga teh a ni. Corrosion rate hi level parukah then theih a ni a:

1. Corrosion resistance kimchang: corrosion rate chu kum khatah 0.001 mm aia tlem a ni a;

2. Corrosion laka invenna nasa tak: corrosion rate 0.001-0.01 mm/kum khatah;

3. Corrosion laka invenna: corrosion rate 0.01-0.1 mm/kum khatah;

4. Corrosion do theihna sang tak: corrosion rate 0.1-1.0 mm/kum khatah;

5. Corrosion resistance tha lo: corrosion rate 1.0-10 mm/kum khatah;

6. Non-corrosion resistance: a corrosion rate chu kum khatah 10 mm aia tam a ni.
