ʻO ka uhi ʻana i ka anticorrosion he ʻaʻahu like ʻole a me ka uhi paʻa i hana ʻia ma ka ʻili o nā paipu kila de-rusting, hiki ke hoʻokaʻawale iā ia mai nā ʻano media corrosive. Ke hoʻohana nui nei nā paipu kila anti-corrosion i nā mea i hoʻohui ʻia a i ʻole nā ​​​​hana hoʻohuihui. Pono kēia mau mea a me nā hale i loaʻa nā waiwai dielectric maikaʻi, nā waiwai kino, nā waiwai kemika paʻa, a me kahi ākea ākea.

ʻO nā pale anti-corrosion o waho: Nā ʻano a me nā kūlana hoʻohana ʻana o nā pale pā waho no nā paipu kila. Hoʻopili ʻia kēia kiʻiʻoniʻoni i ka paia o loko o nā paipu kila e pale aku i ka ʻino ʻana o nā paipu kila, e hoʻemi i ke kūʻē frictional, a hoʻonui i ka dosage. ʻO nā uhi hoʻohana maʻamau he amine-cured epoxy resin a me ka polyamide epoxy resin, a ʻo ka mānoanoa o ka uhi ʻana he 0.038 a 0.2 mm. E hōʻoia i ka hoʻopaʻa paʻa ʻana o ka uhi i ka paia paipu kila.

Pono e hoʻokō ʻia ka mālama ʻana i ka ʻili ma ka paia o loko o ka paipu kila. Mai ka 1970s, ua hoʻohana ʻia nā mea like e uhi i nā paia o loko a me waho o nā paipu kila, e hiki ai ke hoʻopaʻa i nā paia o loko a me waho o nā paipu kila i ka manawa like. Hoʻohana ʻia nā ʻāpana anti-corrosion a me ka wela ma luna o ka ʻaila liʻiliʻi a me ke anawaena o ka wela a i ʻole ka ʻaila aila paipu kila e hōʻemi i ka hoʻokuʻu ʻana o ka wela mai nā paipu kila a i ka lepo.

Hoʻohui ʻia kahi papa hoʻohui o ka insulation thermal a me ka anti-corrosion i waho o ka paipu kila. ʻO ka mea maʻamau i hoʻohana ʻia he polyurethane foam, a ʻo ka mahana kūpono he palupalu kēia mea. No ka hoʻonui ʻana i kona ikaika, hoʻopili ʻia kahi papa o ka polyethylene kiʻekiʻe ma waho o ka insulation e hana i kahi ʻano hui e pale ai i ke komo ʻana o ka wai hāmama i loko o ka insulation.
