I kēia lā, nui nā kūʻai makeke i nā paipu hao hao i kēlā me kēia makahiki ma ka mākeke kila. I ka nānā ʻana i ka ʻenehana hana hana, ua māhele ʻia ka paipu galvanized i ʻelua ʻano: electro galvanized pipe and hot dip galvanized pipe. I ke ola, hoʻohana maʻamau ka poʻe e kapa i ka paipu galvanized wela e like me ka paipu galvanized. ʻOi aku ka maikaʻi o ka hana ma mua o ka paipu galvanized electro. Ma waho aʻe, ma muli o ke kiʻekiʻe o nā kumukūʻai hoʻoili, ʻoi aku ka maikaʻi o ke kumukūʻai paipu kila ma mua o ka paipu galvanized electro. E like me ke kānāwai, ke hoʻohālikelike ʻia me ka paipu kila galvanized i hoʻopaʻa ʻia, ʻaʻole maikaʻi maikaʻi loa ka paipu kila rectangular ma ke ʻano holoʻokoʻa, ʻoi aku ka waiwai o ka pale ʻana i ka corrosion. I nā makahiki i hala iho nei, ma muli o ke kulekele aupuni, ua hoʻopau ʻia ka paipu galvanized electro mai ka mākeke kila.
I ka wā e pili ana i ka paipu galvanized, pono mākou e ʻike e pili ana i ka huaʻōlelo "galvanization". E hana ʻia ka paipu kila galvanized wela i ka hana ʻana kahi e hoʻokumu ʻia ai kahi papa o ka huila a puni nā paipu ma muli o ka hopena kino ma waena o ka zinc hehee a me ka hao. ʻO ka hopena, ʻoi aku ka ikaika o kēia ʻano paipu ma mua o nā ʻano maʻamau. Eia kekahi, ʻo ka paipu kila he uhi ʻokoʻa loa me ka waiwai adhesion ikaika o ka papa zinc i mea e hoʻonui nui ai i ke ola lawelawe o nā paipu. Eia kekahi, ke hoʻohālikelike ʻia me nā paipu maʻamau ʻē aʻe, ʻoi aku ka maikaʻi o ka maikaʻi o ka paipu kila galvanized wela i nā ʻano kumu maoli o ke ola.
ʻO ka ʻōlelo ʻenehana, pili ka galvanization i ka hoʻopili ʻana i kahi uhi zinc pale i ke kino kila a i ʻole ke kino paipu hao, i mea e pale ai i ka pala. ʻO ka galvanizing wela ka hana maʻamau o ka galvanization, kahi e hoʻoheheʻe ʻia ai nā kino paipu i loko o ka ʻauʻau o ka zinc hehee. Ma keʻano laulā, e like me nā mea maka o nā paipu, ʻelua mau ʻāpana o ka paipu galvanized: pre galvanized pipe a me ka wela uʻi galvanized steel pipe. ʻO ka paipu pre galvanized e pili ana i ka paipu welded i loaʻa i ka degreasing, ka wehe ʻana i ka ʻōpala, ka phosphorization, a me ka hoʻomaloʻo ʻana ma mua o ka galvanization. ʻO ka hoʻomaʻamaʻa ʻana ma mua o ka galvanization e ʻae ʻia ka huahana e hoʻopaʻa pono ʻia me ka uhi zinc, a e hōʻoia pū i ka mānoanoa o ka uhi ʻokoʻa, ka hoʻopili ʻana i ka uhi ikaika, a me ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion. Hoʻohana nui ʻia nā paipu pre galvanized i ka wela, ka wai a me nā ʻōnaehana hoʻolako kūlohelohe, ke kahua kūkulu hale ʻōmaʻomaʻo mahiʻai, ke kahua kūkulu kila a me ka ʻōnaehana paipu haʻahaʻa a me ka haʻahaʻa.
