Paipu-laina-ilikai

He ikaika ka paipu metala, maʻalahi ke hana me ka uku ʻole, akā hiki i nā wai ʻino ʻino ke ʻai koke iā ia, mai loko a waho, e kaupalena ana i kona ola.ʻO ka paipu nonmetallic, fiberglass a me nā thermoplastics, ʻaʻole i loaʻa ka ikaika kino o ka paipu metala, akā he kūpaʻa kemika maikaʻi loa.Hoʻohui ʻia ka paipu paipu palani i ka maikaʻi o nā ʻōnaehana paipu maʻamau ʻelua i hoʻokahi.

Hāʻawi nā ʻōnaehana paipu i hoʻopaʻa ʻia i ke kinikini i ke kūpaʻa ʻana o nā plastics a me ka ikaika maoli o ke kila, a i ʻole nā ​​ʻōnaehana pipili metala.He mea maikaʻi kēia no ka mālama ʻana i nā waikawa, corrosive a me nā mea ʻino.Hiki ke hana ʻia ka paipu paʻa paʻa me ka wehe a paʻa ʻia paha i ka liner, akā naʻe, ʻo ka laka i loko o ka liner e hōʻemi i ka hopena o ka ʻokoʻa o ka hoʻonui ʻana ma waena o ka metala a me ka liner.

Nui nā kuhi hewa ma ka mākeke e pili anaPTFE laina paipu.ʻO ke ʻano o ka hana ʻana o kekahi poʻe hana paipu paipu palaki i alakaʻi ʻia iā ʻoe e manaʻoʻiʻo ʻo ia ka hopena i kāu mau koi paipu laina plastik a e mālama i nā kūlana lawelawe āpau mai ka ʻoluʻolu a i ka pōʻino.ʻAʻole pololei kēlā.Hiki i nā ʻōnaehana paipu PTFE i nā pilikia koʻikoʻi:

1. Pono e hoʻoheheʻe ʻia nā paipu laina PTFE a me nā mea hoʻopaʻa laina PTFE e like me ka ASTM kikoʻī no ka paipu i hoʻopaʻa ʻia i ka ʻili a me nā mea i hoʻopaʻa ʻia, F-1545.ʻO PTFE ka fluoropolymer permeable loa a mākou e laina ai a no ka mea ua hoʻokuʻu ʻia, hoʻokuʻu ʻia nā mea āpau e komo i ka liner i ka lewa.

2. Loaʻa i ka PTFE nā waiwai mechanical loa o kekahi fluoropolymer a mākou e laina ai.ʻO nā hui i loko o kahi ʻōnaehana paipu laina PTFE e hoʻopilikia mau ʻia e ka kolo hui a me ke kahe anuanu e like me ka mea i wehewehe ʻia ma ka loulou nūhou wela ma lalo nei.He mea koʻikoʻi nā ami paʻa i ka pono o ka ʻōnaehana paipu i hoʻopaʻa ʻia.ʻO ka mea ʻoi aku ka maikaʻi ma mua o ka hoʻokuʻu ʻana i kāu huahana i ka lewa, ʻo ka hoʻolei ʻana iā ia ma luna o nā limahana, ka lepo, a i ʻole nā ​​​​mea hana ma o kahi hui leaky.

3. ʻO PTFE ka mea liʻiliʻi loa o ka fluoropolymer resin i hoʻohana ʻia i loko o ka paipu i hoʻopaʻa ʻia i ka paipu a me nā mea i hoʻopaʻa ʻia.He 15 a 20% o ke kumukūʻai o nā resins fluoropolymer ʻē aʻe.ʻO ke kālepa ʻana ʻo ia ka hāʻawi ʻana i ke kūpaʻa permeation maikaʻi loa a me nā waiwai mechanical e mālama i ke kālā.Hoʻohana pinepine ʻia nā ʻōnaehana paipu i hoʻopaʻa ʻia no ka lawe ʻana i nā kemika weliweli a weliweli i ke olakino.
