Ke kūkulu ʻana i kahi paipu ikaika "Pale pale"

Hoʻonui i ka ʻenehana Anticorrosion Pipe kila e pale i ka palekana a me ke ola o ka halihali ʻoihana
Ma nā ʻoihana petrochemical, ka lako wai kūlanakauhale, a me ka halihali kinoea kūlohelohe, ʻo nā paipu kila, ma ke ʻano he mau kaʻa halihali koʻikoʻi, e kū mau ana i nā pilikia he nui, me ka pala o ka lepo, ka ʻino ʻana o ka media, a me ka oxidation lewa. Hōʻike ka ʻikepili ʻo ka awelika o ke ola lawelawe o nā paipu kila i mālama ʻole ʻia ma lalo o ʻelima mau makahiki, ʻoiai ʻo ke ola o nā lāʻau anticorrosion maʻamau hiki ke hoʻolōʻihi ʻia i ʻoi aku ma mua o 20 mau makahiki. Me nā hoʻonui ʻoihana a me nā koi palekana kaiapuni i hoʻonui ʻia, ua ulu ka ʻenehana anticorrosion paipu kila mai ka pale uhi hoʻokahi i kahi pae hou o ka pale ola piha e pili ana i nā "hoʻonui mea, hoʻonui kaʻina hana, a me ka nānā akamai."

I kēia manawa, hāʻawi nā ʻenehana anti-corrosion paipu kila nui i nā ʻano ʻōnaehana like ʻole i hoʻopilikino ʻia no nā hiʻohiʻona noi kikoʻī. Ma ka ʻāpana paipu i kanu ʻia, ʻo nā uhi anti-corrosion 3PE (ʻekolu papa polyethylene coating) ka hopena makemake ʻia no nā paipu aila a me ke kinoea mamao loa ma muli o ko lākou kūpaʻa maikaʻi loa i ke kaumaha lepo a me ka cathodic disbonding. ʻO kā lākou ʻano hui, i hana ʻia me ka pauka epoxy kumu, kahi mea hoʻopili waena, a me kahi papa polyethylene waho, hāʻawi i ka pale corrosion a me ka hopena. No nā paipu waikawa a me alkaline i ka ʻoihana kemika, hāʻawi nā uhi fluorocarbon a me ka uhi plastik i nā pono. Hoʻohana ka mea mua i ka inertness kemika o nā fluororesins e kūʻē i nā media corrosive kiʻekiʻe, ʻoiai ʻo ka mea hope e hoʻokaʻawale kino i nā media i lawe ʻia mai ka paipu kila ponoʻī ma ka uhi ʻana i ka paia o loko me nā mea e like me ka polyethylene a me ka polytetrafluoroethylene. Eia kekahi, hoʻohana nui ʻia ka galvanizing hot-dip i nā wahi corrosive iki e like me ka lako wai kūlanakauhale a me nā ʻōnaehana hoʻokahe a me nā kākoʻo kūkulu kila ma muli o kona kumukūʻai haʻahaʻa a me ke kau ʻana maʻalahi. Hāʻawi ka hana anodic sacrificial o ka papa zinc i ka pale electrochemical lōʻihi no ka paipu kila.

ʻO nā hoʻonui ʻenehana a me nā hana hou o ke kaʻina hana e hoʻokele ana i nā hoʻomaikaʻi ʻana i ka maikaʻi o nā paipu kila anti-corrosion. Ke hoʻololi mālie ʻia nei nā kaʻina hana pena lima kuʻuna, ma muli o nā pilikia e like me ka mānoanoa o ka uhi ʻole a me ka hoʻopili maikaʻi ʻole, e nā laina hana automated. Hiki i nā ʻenehana hoʻopuehu electrostatic nui o kēia manawa a me nā ʻenehana hoʻopuehu airless ke hoʻokō i nā hoʻomanawanui mānoanoa o ka uhi i loko o ± 5%. Ma ke kahua o nā mea anti-corrosion, ke hoʻololi mālie nei nā uhi epoxy wai-aloha i ke kaiapuni a me nā uhi anti-corrosion i hoʻololi ʻia e graphene i nā uhi solvent-based, e hōʻemi ana i nā hoʻokuʻu VOC me ka hoʻomaikaʻi ʻana i ke kūpaʻa o ka uhi a me ke kūpaʻa ʻana i ka ʻaʻahu. I ka manawa like, ke hoʻomaka nei nā ʻano nānā akamai e hoʻohui ʻia i loko o nā ʻōnaehana anti-corrosion. Ua lako ʻia nā paipu kila i kekahi mau papahana koʻikoʻi me nā mea ʻike corrosion. Hōʻiliʻili kēia mau mea ʻike i nā hōʻailona corrosion manawa maoli a me nā hōʻailona hōʻino uhi mai ka paia waho o ka pipeline, e hiki ai ke hōʻike mua i nā pilikia hāʻule corrosion a me nā hoʻoponopono pololei.

No nā papahana paipu kila anti-corrosion, ʻo ka manaʻo like o ka ʻoihana ʻo "30% mea hana, 70% kūkulu." Ma mua o ke kūkulu ʻana, pono e hoʻoheheʻe ʻia ka ʻili o ka paipu kila e wehe i ka popo a hōʻoia i ka ʻino o ka ʻili o Sa2.5 a ʻoi aku paha. Hoʻopau pū kēia hana i nā mea haumia e like me ka ʻaila, ka unahi, a me nā mea haumia ʻē aʻe, e hoʻomākaukau ana i ke ala no ka hoʻopili ʻana o ka uhi. I ka wā o ke kūkulu ʻana, pono e hoʻomalu pono ʻia ka mānoanoa o ka uhi, ka mahana hoʻōla, a me ka manawa e pale aku i nā hemahema e like me nā lua pin a me nā leaka uhi. Ma hope o ka hoʻopau ʻana, pono e hōʻoia ʻia ka pono anti-corrosion ma o nā ʻano hana e like me ka hoʻāʻo ʻana i ka ʻālohilohi a me ka hoʻāʻo ʻana i ka hoʻopili ʻana. Ma ka hoʻokumu ʻana i kahi kaʻina hana piha, pani ʻia e pili ana i ka "koho mea - ka mālama ʻana i ka ʻili - ka hoʻokele kūkulu a me ka kaohi - ka mālama ʻana ma hope" hiki ke ʻike maoli ʻia ka waiwai lōʻihi o ka anti-corrosion paipu kila.

Me ka holomua ʻana o nā pahuhopu "kalapona pālua" a me ka hoʻonui ʻana i nā koi palekana ʻoihana, e hoʻomau ka ʻenehana anti-corrosion paipu kila i ka ulu ʻana i nā ʻano ʻōmaʻomaʻo, ʻoi aku ka maikaʻi, a me nā ʻano akamai. I ka wā e hiki mai ana, ʻo nā mea anti-corrosion hou e hoʻohui i nā waiwai haʻahaʻa-kalapona me ka pale lōʻihi, a me nā ʻōnaehana nānā anti-corrosion e hoʻohui i ka ʻenehana māhoe kikohoʻe, e lilo i mea nui no ka noiʻi ʻoihana a me ka hoʻomohala ʻana. E hāʻawi kēia mau mea i kahi pale palekana ikaika no nā paipu ʻoihana like ʻole a hāʻawi i ka hana kiʻekiʻe o ke kahua.
