Fluoroplastic lined a ni a, a hnim hring lo thei lochu steel emaw iron butterfly valve pressure-bearing parts chhung lam bang emaw, butterfly valve chhung lam part pawn lam emaw-ah molding (or inlay) method hmanga polytetrafluoroethylene resin (or profile processed) dah a ni. Butterfly valve-te hian corrosive media chak tak laka an thiltihtheihna danglam tak chu butterfly valve chi hrang hrang leh pressure vessel-ah siam a ni.
Anti-corrosion materials-ah chuan PTFE hian performance tha tak a nei a, a danglam bik lo. Melten metal, elemental fluorine leh aromatic hydrocarbons bakah hian hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, strong oxidant, concentrated , alternating dilute acid, alternating alkali leh organic agent hrang hrang te chu random reaction a ni. Butterfly valve chhung lam wall-a PTFE lining hian PTFE material chakna hniam tak tlin lohna a hneh mai bakah butterfly valve theme material-a corrosion resistance buaina pawh a chinfel sak bawk.

6. Forfluorine hmanga siam butterfly valve chu a nipipeline-ah chuan toxic, flammable, explosive leh strong corrosive medium hmangin, pressure hnuaia packing thlak khap tlat a ni. Fluorine-lined butterfly valve hian design-ah upper sealing function nei mahse, pressure hnuaia packing thlak hi a tha lo.
7. Pipeline spontaneous combustion medium nei tan chuan ni êng emaw pawn lam kangmei avanga hlauhawm lo awm tur ven nan ambient temperature leh working condition temperature te chu medium spontaneous combustion point aia tam a nih loh nan hmalak tur a ni.
Medium hman tur: acid-base salt concentration hrang hrang leh organic solvent thenkhat.
