I ka nui aʻe o ka nānā ʻana o ka poʻe i ka mālama ʻana i ke kaiapuni a me ka hoʻomohala hoʻomau, ua maʻamau ka hoʻohana ʻana o nā pipeline i nā ʻoihana like ʻole a me nā māla. pōʻino nui iā lākou, ka hopena o nā kumukūʻai mālama ʻoi aʻe a, i kekahi mau hihia, nā ulia a i ʻole nā pōʻino kaiapuni.No ka lanakila ʻana i kēia mau pilikia, hiki ke uhi ʻia nā paipu me nā pale pale e like me3LPE uhia me nā uhi FBE e hoʻonui i ko lākou pale ʻana i ka corrosion a hoʻomaikaʻi i ko lākou lōʻihi.
ʻO ka uhi ʻana o 3LPE, ʻo ia hoʻi, ka uhi polyethylene ʻekolu-layer, he ʻōnaehana hoʻoheheʻe multi-layer i loaʻa i kahi papa kumu fusion bonded epoxy (FBE), kahi ʻāpana adhesive a me kahi papa polyethylene topcoat.Loaʻa i ka ʻōnaehana hoʻopili ke kūpaʻa corrosion maikaʻi loa, ka ikaika mīkini a me ke kūpaʻa hopena, hoʻohana nui ʻia i lokopaipu aila a me ke kinoea, nā paipu wai a me nā ʻoihana ʻē aʻe kahi e hōʻike ʻia ai nā paipu i nā wahi corrosive.
ʻO ka uhi FBE, ma ka ʻaoʻao ʻē aʻe, he ʻōnaehana pale pale hoʻokahi i loaʻa i kahi uhi epoxy pauka thermosetting i hoʻopili ʻia i ka ʻili o ka paipu.ʻO ka ʻōnaehana hoʻopili he adhesion maikaʻi loa, abrasion kiʻekiʻe a me ka hopena hopena a me ke kūpaʻa kemika maikaʻi, kūpono ia no ka pale ʻana i ka pipeline i nā ʻoihana like ʻole e like me ka aila a me ke kinoea, ka wai a me ka halihali.
Hoʻohana nui ʻia ka 3LPE coating a me ka FBE coating i ka ʻenehana pipeline ma muli o kā lākou mau mea pale maikaʻi.Eia nō naʻe, ʻokoʻa ka laulā o kā lākou noi ma muli o ke kūlana kikoʻī e pono ai ka pipeline e mālama.
Ma nā paipu aila a me ke kinoea, ʻoi aku ka maikaʻi o ka uhi ʻana o 3LPE no ka mea hiki iā ia ke pale i ka hana corrosive o ka aila a me ke kinoea, a me ka hopena a me ka friction o ka lepo a puni.Eia kekahi, hiki i nā ʻāpana 3LPE ke pale aku i ka disbonding cathodic, ʻo ia ka hoʻokaʻawale ʻana o nā uhi mai nā ʻili metala ma muli o nā hopena electrochemical.He mea koʻikoʻi kēia no nā pipeline i pale ʻia i ka corrosion.
In paipu wai, ʻO ka uhi FBE ka koho mua loa no ka mea hiki iā ia ke pale pono i ka hoʻokumu ʻana o ka biofilm a me ka ulu ʻana o ka bacteria, hiki ke hoʻohaumia i ka maikaʻi o ka wai.He kūpono nō hoʻi ka uhi FBE no nā paipu e lawe ana i nā media abrasive, e like me ke one, ka ʻiliʻili a i ʻole ka lepo, ma muli o kona kūpaʻa maikaʻi loa.
I ka pipeline kaʻa, hiki ke hoʻohana ʻia ka 3LPE coating a i ʻole FBE coating e like me ke kūlana kūikawā o ka halihali.Inā ʻike ʻia ka pipeline i kahi pōʻino, e like me ke kai moana, ʻoi aku ka maikaʻi o ka uhi ʻana o 3LPE no ka mea e pale ana i ka hana ʻino o ke kai a me nā mea ola kai.Inā hōʻike ʻia ka paipu i nā pāpaʻi abrasive e like me nā minerala a i ʻole nā ores, ʻoi aku ka maikaʻi o ka uhi FBE no ka mea hiki ke hāʻawi i ke kūpaʻa ʻoi aku ka maikaʻi ma mua o ka uhi ʻana o 3LPE.
I ka hōʻuluʻulu ʻana, ʻokoʻa ke ʻano o ka hoʻohana ʻana i ka uhi 3LPE a me ka uhi FBE e like me nā kūlana kikoʻī oʻenehana paipu.Loaʻa i nā ʻōnaehana pale ʻelua ko lākou pono ponoʻī a me nā hemahema.ʻO ke koho ʻana o ka ʻōnaehana uhi pono e noʻonoʻo pono i nā ʻano like ʻole e like me ke ʻano o ka waena, ka mahana a me ke kaomi o ka pipeline, a me ke kaiapuni a puni.Me ka hoʻomau mau ʻana o ka ʻenehana pipeline, ke manaʻoʻiʻo nei mākou e ʻoi aku ka nui o nā ʻōnaehana uhi hou a maikaʻi e hoʻokō ai i nā pono ulu o ka pale a me ka palekana.
Loaʻa iā mākou kahi hale hana anti-corrossion e hiki ke hana i ka 3PE coating, epoxy coating etc.
