Ma ke ʻano he mea nui i ka ʻenekinia paipu hou, ua hoʻohana nui ʻia nā paipu kila anti-corrosion i ka ʻoihana ʻaila, kinoea, kemika, a me ka wai ma muli o ko lākou kūpaʻa maikaʻi loa a me ke ola lōʻihi. Hōʻike mua ʻia ko lākou ʻano ʻenehana ma nā ʻano ʻekolu: -ka hoʻolālā ʻana i ka corrosion coating, koho mea, a me ka hana hou.
ʻO ka mea mua, ʻo ka uhi-kuʻi ʻino o nā paipu kila anti-corrosion ka ʻenehana kumu. ʻO nā ʻano hana anti-corrosion maʻamau he ʻekolu-layer polyethylene (3PE), epoxy coal tar, a me ka polyurethane coatings. Hoʻohui ka 3PE anti-corrosion coating i ka hoʻopili ikaika ʻana o ka pauka epoxy, ka hopena hoʻololi o ka mea hoʻopili, a me ka hopena o ka polyethylene e hana i ka -paʻa paʻa paʻa e pale pono i ka lepo, ka makū, a me ka pāpaʻi kemika. ʻO nā uhi pauda epoxy, ma o ka -sintering wela kiʻekiʻe, e hana i kahi kiʻiʻoniʻoni pale ʻeleʻele kūpono no nā kaiapuni kiʻekiʻe a me ke kiʻekiʻe. Eia kekahi, ua hoʻomaikaʻi hou ka hoʻohana ʻana i nā ʻāpana anticorrosion-nano{15}}i hoʻololi ʻia i ka pale ʻana o ka pale a me ka pale ʻana i ka wā.
ʻO ka lua, ʻo ke koho ʻana i nā mea kumu no nā paipu kila anti-corrosion pili pono i kā lākou hana holoʻokoʻa. ʻO nā paipu kila ʻole a welded nā ʻano nui o nā paipu. Hoʻohana pinepine ʻia nā paipu kila maʻemaʻe, ma muli o ka nele o nā weld a me ka ikaika kiʻekiʻe, no ka hoʻouna ʻana i ke kaomi kiʻekiʻe. ʻO nā paipu kila welded, me ka hoʻohana ʻana i ka -frequency kiʻekiʻe a i ʻole nā kaʻina hana kuʻihao arc submerged e hōʻemi i nā kumukūʻai, kūpono ia no nā kūlana hana maʻamau. No ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion, ua galvanized a i ʻole ke kila kila paha kekahi mau paipu kila, akā ʻoi aku ke kumukūʻai a hoʻohana nui ʻia i nā kaiapuni kūikawā.
ʻO ka mea hope loa, ʻo ka hana hou i nā kaʻina hana anti-corrosion ke kī i ka hoʻonui ʻenehana. Hoʻohui ʻia nā ʻano hana anti-corrosion e like me ka hoʻoheheʻe ʻana i ke arc a me ka -dip galvanizing me nā mea hoʻopale kemika e hana i kahi ʻōnaehana pale hui. Eia kekahi, ʻo ka hoʻohana ʻana i ka ʻenehana pale cathodic, me ka hoʻohana ʻana i nā anodes i hoʻohālikelike ʻia i kēia manawa a i ʻole nā anodes, e hoʻonui i ke ola o nā paipu kila. ʻO ka hoʻokomo ʻana i nā ʻenehana hoʻoheheʻe ʻakomi a me nā ʻenehana ʻike naʻauao e hōʻoia i ka lokahi a me ka maikaʻi kūlike o ka uhi -anticorrosion.
ʻO ka hōʻuluʻulu manaʻo, ma o ka -papahana anti-corrosion design, kiʻekiʻe-mea kumu, a me nā kaʻina hana kiʻekiʻe, anti-corrosion steel pipes e loaʻa i ka corrosion resistance, lōʻihi ka lawelawe ʻana, a me nā kumu kūʻai haʻahaʻa no ka mālama ʻana, e lilo ia i mea hoʻonā ʻenehana ponoʻī no nā papahana paipu hou.
