Elua ano o ka paipu laina: 1. Paipu paa paa.He mea maʻamau i ʻike ʻia ʻo ka huki huki, ʻo ia hoʻi, tetrafluoro-pipe i ʻoi aku ka nui ma mua o ka paipu kila i loko o ke anawaena, ma o ka mīkini traction lining i loko o ka paipu kila 2.Pipe loose lining.ʻo ia ke anawaena o waho o ka paipu tetrafluoro ʻoi aku ka liʻiliʻi ma mua o ke anawaena o loko o ka paipu kila, i hoʻopaʻa pololei ʻia i loko o ka paipu kila ma o ka hoʻokomo lima.

mea nui: - He kūpono ka PTFE (F4) no ka lawe ʻana i ka medium corrosive ikaika ≤120 ℃, e like me ka dilute HCl, HNO3, H2SO4, HF, NaOH, etc. He laulā ke kū'ē - PP a me PO lawelawe wela ≤100 ℃, kūpono no ka liʻiliʻi o ka solvent corrosive medium transport, corrosion resistance maʻamau.

Hoʻokomoʻia ka'ōpala i loko o ka paipu paipu, a hoʻokomoʻia ka pauka tetrafluorin i loko o ia mea no ka hoʻokumuʻana.

Mea nui: - Ua kūpono ʻo PTFE F4 no ka lawe ʻana i ka medium corrosive ikaika ≤150 ℃, e like me ka dilute HCl, HNO3, H2SO4, HF, NaOH, a pēlā aku.- Hoʻohana ʻo PFA no ka lawe ʻana i ka media corrosive ikaika ≤200 ℃, nā ʻano ʻē aʻe e like me PTFE

Hoʻomaʻamaʻa mua ʻia ka ʻili o nā paipu paipu, a laila hoʻomehana ʻia nā paipu paipu, hoʻokomo ʻia ka pauka ETFE i loko o ka paipu ma hope o ka loaʻa ʻana o ka mahana i ka maʻamau, ʻo ka ETFE i ka mokuʻāina heheʻe ua hoʻopili like ʻia i ka paia o loko o nā mea hana ma o 3D rotation, a ʻo ka hoʻolili ʻana a me ke ʻano.Mea nui: ETFE (F40), no ka lawe ʻana i ≤150 ℃ ikaika corrosive medium, e like me ka dilute HCl, HNO3, H2SO4, HF, NaOH, a pēlā aku.Hiki ke kū'ē i ka micro-negative pressure
