ʻAʻole mākou he malihini i nā paipu kila anti-corrosion 3PE. ʻO kēia ʻano paipu kila he hana anti-corrosion maikaʻi, no laila hoʻohana pinepine ʻia nā paipu kila 3PE e like me nā paipu kila i kanu ʻia. Eia naʻe, pono nā paipu kila anti-corrosion 3PE i kekahi mau hoʻomākaukau ma mua o ka kanu ʻana. I kēia lā, e lawe ka mea hana pipeline iā ʻoe e hoʻomaopopo i ka hoʻomākaukau ʻana no nā paipu kila anti-corrosion 3PE ma mua o ka kanu ʻana.

Ma mua o ka hoʻomaopopo ʻana i ka uhi ʻana, e hoʻomaopopo mua kākou i ka maikaʻi o nā paipu kila anti-corrosion 3PE: hoʻohui ia i ka ikaika mechanical o nā paipu kila a me ke kūpaʻa ʻana o nā plastics; ʻoi aku ka nui o ka uhi ʻana o ka pā i waho ma mua o 2.5mm, kūʻokoʻa a kū ʻole i ka puʻu; liʻiliʻi ka ʻāpana friction o ka paia i loko, hiki ke hōʻemi i ka hoʻohana ʻana i ka ikehu; ʻo ka pā o loko e kū i nā kūlana olakino o ka ʻāina a palekana a ʻaʻohe pōʻino; ʻO ka paia o loko he laumania a ʻaʻole maʻalahi ka paona, a he hana hoʻomaʻemaʻe maikaʻi.

Ma mua o ke kanu ʻana i nā paipu kila anti-corrosion 3PE, pono e hoʻomaʻemaʻe mua ʻia ke kaiapuni a puni. Pono nā limahana nānā a me ka hoʻonohonoho ʻana e hana i nā pōkole ʻenehana me nā luna a me nā mea hana mīkini e komo ana i ka hana hoʻomaʻemaʻe, a ma kahi o hoʻokahi laina o nā limahana pale e komo i ka hoʻomaʻemaʻe ʻana i ke kāʻei hana. Pono e nānā inā ua hoʻoneʻe ʻia ka paipu kila anti-corrosion 3PE, ka puʻu keʻa, a me ka puʻu hōʻailona o lalo o ka lepo i ka ʻaoʻao o ka lepo i haʻalele ʻia, inā ua helu ʻia nā hale o luna a me lalo, a inā ʻo ka pololei. o ka hele ana i loaa.

Hiki ke hoʻohana ʻia nā hana mīkini ma nā wahi ākea, a hiki ke hoʻomaʻemaʻe ʻia nā ʻōpala i loko o ka wahi hana me ka hoʻohana ʻana i ka bulldozer. Eia naʻe, i ka wā e pono ai ka paipu kila anti-corrosion 3PE e hele i nā pilikia e like me nā auwai, nā kualono, a me nā pali pali, pono e ʻimi i kahi ala e hoʻokō ai i nā koi o ke kaʻa o ka halihali a me nā lako hana.

Pono e hoʻomaʻemaʻe ʻia ka wahi hana kūkulu e like me ka hiki, a inā aia nā ʻāina mahiʻai, nā kumulāʻau hua, a me nā mea kanu a puni, pono e noho liʻiliʻi nā ʻāina mahiʻai a me nā ululāʻau hua; inā he ʻāina wao nahele a i ʻole ka ʻāina paʻakai, pono e luku ʻia nā mea kanu o ka ʻili a me ka lepo kumu i mea liʻiliʻi e pale a hōʻemi i ka ʻino o ka lepo; i ka wā e hele ai ma nā kahawai wai a me nā kahawai wai, pono e hoʻohana ʻia nā ʻōpala i kanu mua ʻia a me nā mea wai ʻē aʻe, a ʻaʻole e keakea ʻia ka hana mahiʻai.

No ka hoʻokō ʻana i nā pono maikaʻi o nā paipu kila anti-corrosion, pono ka uhi ʻana i nā ʻano ʻekolu:
ʻO ka mea mua, maikaʻi ke kū'ēʻana i ka corrosion: ʻO ka uhi i hanaʻia e ka uhiʻana ke kumu o ka 3PE steel pipe corrosion resistance. Pono ka paʻa ʻana o ka uhi i ka wā e launa pū ai me nā mea hoʻoheheʻe ʻia e like me nā waikawa, nā alkali, nā paʻakai, ka ʻilikai ʻoihana, ka lewa kemika, a me nā mea ʻē aʻe, a ʻaʻole hiki ke ʻānai ʻia, hoʻoheheʻe ʻia, a decomposed paha e kēia mau mea, e waiho wale i ka hana kemika me ka mea e pale aku ai i ka hana ʻana o nā mea ʻino hou.
ʻO ka lua, maikaʻi ʻole impermeability: No ka hana ʻana i ka uhi hiki ke hoʻopaʻa maikaʻi i ke komo ʻana o nā wai a me nā kinoea me ka permeability ikaika a hoʻoulu i ka corrosion i ka ʻili o ka pipeline i ka wā e hoʻopili ai i ke kikowaena, pono ka impermeability maikaʻi i ka uhi ʻia e ka uhi.
ʻO ke kolu, ka hoʻopili maikaʻi a me ka maʻalahi: Ua ʻike mākou a pau i ka hui pū ʻana o ka pipeline a me ka uhi ʻana, ʻaʻole e haki a hāʻule paha ka pipeline ma muli o ka haʻalulu a me ka liʻiliʻi deformation e hōʻoia i ka pale ʻana o ka pipeline. No laila, ʻo ka uhi i hana ʻia e ka uhi ʻana e koi ʻia e loaʻa ka adhesion maikaʻi a me kekahi ikaika mechanical.
