ʻO ka paipu galvanized wela e hoʻoheheʻe i ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi ʻāpana alloy, i hui ʻia ka matrix a me ka uhi.ʻO ka galvanizing wela ka hoʻopili mua ʻana i ka paipu kila.I mea e wehe ai i ka hao hao ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, e hoʻomaʻemaʻe ʻia i loko o kahi pahu me ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka wai i hui ʻia o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i In ka pahu hoʻopaʻa wela wela.Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.Hoʻokomo ʻia ka matrix galvanized galvanized steel matrix paʻakikī me ka hoʻoheheʻe ʻana i hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao me ka paʻa paʻa.Hoʻohui ʻia ka ʻāpana alloy me ka papa zinc maʻemaʻe a me ka matrix paipu kila, no laila ua ikaika kona pale ʻana i ka corrosion.

Cold galvanized paipu mea electro-galvanized, a me ka nui o ka galvanizing mea uuku loa, wale 10-50g/m2, a me kona corrosion kū'ē i oi aku ka hewa ma mua o ka wela-hoʻauheʻe galvanized paipu.ʻO ka hapa nui o nā mea hana paipu galvanized maʻamau ʻaʻole hoʻohana i ka electro-galvanization (cold plating) i mea e hōʻoia ai i ka maikaʻi.ʻO kēlā mau ʻoihana liʻiliʻi wale nō me nā mea liʻiliʻi a me nā mea hana kahiko e hoʻohana i ka electro-galvanization, a ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o kā lākou kumukūʻai.Ua hoʻolaha kūkala ke Keʻena ʻOihana e hoʻopau ʻia nā paipu anu me ka ʻenehana hope, a ʻaʻole ʻae ʻia ka hoʻohana ʻana i nā paipu wai a me ke kinoea.ʻO ka papa galvanized o ka paipu kila kila he mea electroplated, a ua hoʻokaʻawale ʻia ka papa zinc mai ka matrix pipe kila.He lahilahi ka papa zinc, a pili wale ka papa zinc i ka substrate paipu kila a maʻalahi ke hāʻule.No laila, ʻilihune kona pale ʻana i ka corrosion.I nā hale i kūkulu hou ʻia, pāpā ʻia ka hoʻohana ʻana i nā paipu kila i hoʻoheheʻe ʻia e like me nā paipu wai.
