E lua ituaiga o paipa fa'apipi'i: 1. Paipa fa'amau.E masani ona taʻua o le toso faagaau, o lona uiga, tetrafluoro-paipa teisi lapoʻa atu nai lo le uamea faagaau totonu lautele, e ala i masini traction lining i totonu o le paipa uamea 2.Pipe lining tatala.o le lautele pito i fafo o le paipa tetrafluoro e laʻititi laʻititi nai lo le totonugalemu o le paipa uamea, lea e tuʻu saʻo i totonu o le paipa uamea e ala i le faʻaofiina o tusi lesona.

mea autu: - PTFE (F4) e talafeagai mo le felauaiga malosi corrosive ala ≤120 ℃, e pei o le dilute HCl, HNO3, H2SO4, HF, NaOH, ma isi - PE vevela auaunaga ≤80 ℃, talafeagai mo felauaiga lautele vaivai corrosive auala, pala. teteʻe lautele - PP ma PO auaunaga vevela ≤100 ℃, talafeagai mo se vaega itiiti o solvent corrosive felauaiga auala, corrosion tetee e masani lava.

O loʻo tuʻuina le limu i totonu o le paipa faʻapipiʻi, ma faʻapipiʻi le paʻu o le tetrafluorin i totonu mo le faʻapipiʻiina o le faʻapipiʻiina. A maeʻa le faʻamalo, e faʻafefeteina ma faʻamalosia i totonu o se ogaumu vevela maualuga, ona faʻamafanafanaina lea e fai.

Mea autu: - PTFE F4 e talafeagai mo le momoliina malosi corrosive ala ≤150 ℃, e pei o le dilute HCl, HNO3, H2SO4, HF, NaOH, ma isi.- Fa'aoga PFA mo le fa'asalalauina o fa'asalalauga malosi ≤200 ℃, o isi uiga e tutusa ma le PTFE

O le pito i luga o le paipa o loʻo faʻapipiʻiina muamua, ona faʻamafanafanaina lea o paipa paipa, faʻapipiʻi le paʻu ETFE i totonu o le paipa pe a oʻo le vevela i le tulaga masani, ETFE i le tulaga faʻafefeteina o loʻo faʻapipiʻi tutusa i le puipui i totonu o meafaigaluega e ala i le 3D rotation, ma i'u ina mālūlū ma fa'apena.Mea autu: ETFE(F40), mo le momoliina ≤150℃ malosi corrosive auala, e pei o le dilute HCl, HNO3, H2SO4, HF, NaOH, ma isi.E masani ona mafai ona tete'e micro – le lelei omiga
