3PE paipu kila anti-corrosivee pili ana i ka insulation o ka paipu kila e hōʻoia i ka wela o loko o ka paipu kila hana a me ka wela o ka ʻili i kahi ʻano hana ʻokoʻa e lohi a pale paha i ka corrosion a me ka deterioration ma lalo o ka hana kemika a me ka electrochemical o ka mea waho, ma muli paha o nā hana metabolic o nā microorganisms.Keʻano anti-corrosion.ʻO ke ʻano o ka anti-corrosion ka mea maʻamau e kau i ka pena ma ka ʻili o nā paipu metala i hala i ka wehe ʻana i ka ʻōpala i mea e pale ai iā lākou mai nā ʻano media corrosive.ʻO kēia kekahi o nā ala hou loa no ka paipu kila anti-corrosion.ʻO nā ʻano mea hoʻopili a me nā kūlana noi.Hoʻopili ʻia ka pale pale anti-corrosion i loko o ke kiʻiʻoniʻoni ma ka paia o loko o ka paipu e pale ai i ka corrosion i loko o ka paipu a hoʻemi i ke kūpaʻa frictional.No ka hoʻohaʻahaʻa ʻana i ka wela o ka pipeline i ka lepo, hoʻohui ʻia kahi papa hana o ka insulation thermal a me ka anti-corrosion i waho o ka pipeline.Inā he paipu polyethylene ka paipu pale waho, ʻaʻohe pono e nalowale i ka pale corrosion.No ka mea he maikaʻi loa ka polyethylene i ka haʻahaʻa haʻahaʻa, kūpaʻa kemika maikaʻi, a me ka nui o ka waika a me ka corrosion alkali, ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka lumi wela a he haʻahaʻa haʻahaʻa ka wai.

ʻO ʻekolu-layer polyethylene anti-corrosion kekahi o nā ʻōnaehana ʻenehana mua loa no ka anti-corrosion waho o nā pipeline kanu ʻia ma ka home a ma waho.Loaʻa iā ia ka hana anti-corrosion maikaʻi, haʻahaʻa haʻahaʻa wai absorption rate, a me ka ikaika mechanical holomua.I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia i loko o ka wai i kanu ʻia i ka home, ke kinoea, a me nā paipu aila.
