I ke kaʻina hana anti-corrosion o ka aila a me ke kinoea pipelines, ʻo ka mālama ʻana i ka ʻili o ka paipu kila seam pololei kekahi o nā kumu nui e hoʻoholo ai i ke ola lawelawe o ka pipeline anti-corrosion.Ma hope o ka noiʻi ʻana e nā ʻoihana noiʻi ʻoihana, pili ke ola o ka papa anti-corrosion i nā mea e like me ke ʻano o ka uhi ʻana, ka maikaʻi o ka uhi ʻana a me ke kaiapuni kūkulu.Hoʻomaikaʻi mau ʻia nā koi no ka ʻili o ka paipu kila hili pololei, a hoʻomaikaʻi mau ʻia nā ʻano hana lapaʻau o ka paipu kila hili pololei.ʻO ke ʻano o ka wehe ʻana i ka hili ʻana o ka paipu kila hili pololei, ʻo ia ka mea:

1. Hoomaemae
E hoʻohana i nā solvents a me nā emulsions e hoʻomaʻemaʻe i ka ʻili kila no ka wehe ʻana i ka ʻaila, ka momona, ka lepo, nā lubricants a me nā mea kūlohelohe like, akā ʻaʻole hiki ke hoʻoneʻe i ka ʻōpala, ka unahi oxide, welding flux, etc. ʻo ia hoʻi i nā hana anti-corrosion.

2. Piʻi ʻana
ʻO ka maʻamau, hoʻohana ʻia nā ʻano ʻelua o ka pickling kemika a me ka electrolytic no ka pickling, a ʻo ka pickling kemika wale nō i hoʻohana ʻia no ka pipeline anticorrosion, hiki ke wehe i ka unahi oxide, ka ʻōpala, a me ka uhi kahiko.ʻOiai hiki i ka hoʻomaʻemaʻe kemika ke hoʻokō i ka ʻili i kahi pae o ka maʻemaʻe a me ka ʻinoʻino, he pāpaʻu kona kumu heleuma a maʻalahi hoʻi e hoʻohaumia i ke kaiapuni a puni.

3. Mea hoʻoneʻe ʻōpala
Hoʻohana nui i nā mea hana e like me nā pulupulu uea e poli i ka ʻili o ke kila, hiki ke hoʻoneʻe i ka unahi oxide loose, rust, welding slag, a me nā mea ʻē aʻe. pae.Inā hoʻopili ʻia ka ʻili kila i kahi paʻa paʻa o ka hao oxide, ʻaʻole kūpono ka hopena hoʻohemo ʻana o nā mea hana, a ʻaʻole hiki ke hoʻokō ʻia ka hohonu o ka heleuma i koi ʻia no ka hana anti-corrosion.

4. E kāpīpī i ka ʻōpala
ʻO ka jet derusting ka mea e hoʻohuli ai i nā ʻāpana jet e hoʻololi i ka wikiwiki ma o ka mīkini mana kiʻekiʻe, no laila e hoʻoheheʻe ʻia nā abrasives e like me ke kila pana, ke one kila, nā ʻāpana uwea hao, nā minerala, a pēlā aku. paipu ma lalo o ka ikaika centrifugal ikaika o ka kaʻa, ka mea hiki ole wale wehe oxides , rust a me ka lepo, a me ka pololei seam kila paipu hiki ke hoʻokō i ka pono like roughness ma lalo o ka hana o ka ino a me ka friction o ka abrasive.

Ma hope o ka pīpī ʻana a me ka wehe ʻana i ka ʻōpala, ʻaʻole hiki iā ia ke hoʻonui wale i ka adsorption kino ma ka ʻili o ka paipu, akā e hoʻonui pū i ka adhesion mechanical ma waena o ka papa anti-corrosion a me ka ʻili o ka paipu.No laila, ʻo ka jet derusting kahi ala derusting kūpono no ka pipeline anticorrosion.ʻO ka ʻōlelo maʻamau, hoʻohana nui ʻia ka pana kī no ka mālama ʻana i ka ʻili o loko o nā paipu, a hoʻohana nui ʻia ka puhi ʻana no ka mālama ʻana i waho o nā paipu kila humuhumu pololei.

I ke kaʻina hana, pono e koi ʻia nā hōʻailona loea e pili ana i ka wehe ʻana i ka ʻōpala e pale i ka pōʻino i ka paipu kila seam pololei i hana ʻia e nā hewa hana.ʻO ka hoʻopili ʻana he ʻenehana i hoʻohana pinepine ʻia i ka ʻoihana paipu kila.
