Paipu uʻi kūʻē uila (RW) galvanized pipe hoʻohana ʻia i ke kūkulu ʻana, nā ʻōnaehana paipu, ka hoʻoili ʻana i ka ikehu a me nā māla ʻē aʻe ma muli o kona versatility, lōʻihi a me ka pale ʻana i ka corrosion. ʻO kēia ka hoʻolauna pōkole i ka paipu ERW gi.

1.ERW paipu kila
ʻO ka ERW, ʻo ia hoʻi, ʻo ia ke ʻano o ka hoʻoheheʻe ʻana i ka paipu e hoʻohana ai i ke kumu o ka hoʻomehana kū'ē e hoʻopili i ke au uila ma nā hui o nā wili kila e hoʻoulu ai i ka wela e hoʻoheheʻe ai i ka metala, a laila hoʻohui i nā poʻo wili kila ʻelua.
2. ERW paipu galvanizing kaʻina hana
E like me ka sandblasting, pickling a me ka phosphating, galvanizing kekahi ʻenehana lapaʻau ʻili no nā paipu metala. ʻO ka Galvanizing e pili ana i ka ʻenehana o ka uhi ʻana i kahi papa o ka zinc ma ka ʻili o ka metala, ka hao a i ʻole nā mea ʻē aʻe no ka aesthetics a me ka pale ʻana. ʻO ka mana electrode maʻamau o ka zinc he -0.76V. No nā substrate kila, ʻo ka zinc coating he uhi anodic. Hoʻohana nui ʻia e pale i ka corrosion o ke kila. ʻO kāna hana pale e pili pono ana i ka mānoanoa o ka uhi. Ma hope o ka hoʻololi ʻia ʻana o ka uhi zinc, hoʻoluʻu ʻia a uhi ʻia paha me ka pale ʻālohilohi, hiki ke hoʻomaikaʻi maikaʻi ʻia kona mau mea pale a me nā mea hoʻonaninani.
ʻO ke ala nui i hoʻohana ʻia no ka galvanizing ili o ERW ʻo ia ka wela wela.
Ua hoʻomohala ʻia ka hoʻoheheʻe wela wela mai ke ʻano hana wela kahiko. He 170 makahiki kona moʻolelo mai ka hoʻohana ʻana o Farani i ka galvanizing wela i ka ʻoihana i ka makahiki 1836. Eia naʻe, ua hoʻomohala ʻia ka ʻoihana galvanizing wela i ka nui i nā makahiki he kanakolu i hala me ka hoʻomohala wikiwiki ʻana o ke kila ʻōwili anuanu.
ʻO ke kaʻina hana o ka hot-dip gi steel pipe ka mea nui: ka hoʻomākaukau paipu kumu → pre-plating treatment → hot dip plating → post-plating treatment → hoʻopau huahana nānā, etc. E like me ka maʻamau, ua māhele ʻia ke kaʻina hana galvanizing wela ʻelua mau ʻāpana: ka hoʻopili ʻana i waho a me ka annealing i loko o ka laina e pili ana i nā ʻano hana lapaʻau pre-plating like ʻole.
Loaʻa i ka pahu ERW kekahi ʻano galvanizing i kapa ʻia ʻo electro-galvanizing. Ua kapa ʻia ʻo Electro-galvanizing he galvanizing anuanu, ʻo ia ke kaʻina hana e hoʻohana ai i ke kumu o ka electrolysis e hana i kahi ʻaʻahu like, paʻa, a paʻa maikaʻi i ka zinc ma ka ʻili o ka huahana.
3.Hot-dip galvanized vs electro-galvanized ERW paipu
Hiki ke hoʻokaʻawale ʻia ka electro-galvanizing a me ka wela wela e ka mānoanoa o ka uhi ʻana, ka pale ʻana i ka corrosion, ka laulā noi, nā waiwai kino a me ke kumukūʻai. He hoʻolauna kikoʻī kēia:
(1) Ka mānoanoa uhi
ʻOi aku ka nui o ka mānoanoa o ka uhi ʻana o ka galvanizing wela, ma ka maʻamau 50 a 60 microns, a i ʻole 600 microns; ʻoiai he lahilahi ka mānoanoa o ka uhi ʻana o ka electro-galvanizing, maʻamau 5 a 15 microns.
(2) Ke kū'ē i ka corrosion
ʻOi aku ka ʻoi aku o ka ʻeleʻele o ka zinc layer o ka hot-dip galvanizing a emi ʻole i ka corrosion e nā oxides a me nā paʻakai i loko o ke kaiapuni, no laila ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion; ʻO ka electro-galvanizing ka mea ʻoi aku ka lahilahi a ʻoi aku ka maʻalahi o ka ʻaʻahu mechanical a me ka corrosion oxide.
(3) Laulā noi
He mea kūpono ia no nā hale kila, nā kaʻa, nā mīkini mahiʻai, ke kūkulu ʻana a me nā moku, a me nā mea ʻē aʻe, a hana maikaʻi loa i nā wahi paʻakikī; Hoʻohana nui ʻia ka electro-galvanizing no nā huahana liʻiliʻi, palupalu, a hana maikaʻi i nā wahi ʻoluʻolu. .
(4) Nā waiwai kino
He oolea ka ili o na paipu ERW galvanized wela, he manoanoa ka papa zinc, e hoike ana i na pua zinc, a he olinolino ke ano; he laumania ka ili o na paipu kila ERW electro-galvanized, a lahilahi ka papa zinc.
(5) He ʻokoʻa nā kumukūʻai.
Hot-dip galvanizing i ka mānoanoa zinc papa, maikaʻi lōʻihi, a me ka 'ano kiʻekiʻe kumu kūʻai, akā, he lōʻihi lawelawe ola, no laila, ua oi aku ka waiwai; ʻO ka electro-galvanizing he'āpana zinc lahilahi, he kumu kūʻai haʻahaʻa, akā he ola pōkole.
Ma keʻano laulā, ʻoi aku ka maikaʻi o ka galvanizing wela ma mua o ka electro-galvanizing ma ke ʻano o ka corrosion resistance, corrosion resistance and mechanical properties, aʻo ka electro-galvanizing e kūpono i nā manawa kahi i kiʻekiʻe ʻole ai ka mānoanoa o ka papa zinc.
4.Pono o nā paipu ERW galvanized:
(1) ka pale ʻana i ka corrosion a me ka lōʻihi
ʻO kekahi o nā pōmaikaʻi nui o nā paipu kila galvanized ERW ʻo ko lākou kūʻokoʻa corrosion a me ka lōʻihi. Hoʻohana ʻia ka zinc coating ma ke ʻano he anode kaumaha, ʻoi aku ka maikaʻi o ka corroding no ka pale ʻana i ke kila o lalo mai ka ʻōpala a me ka ʻino. Hoʻonui kēia i ke ola o nā paipu, ʻoiai ma nā wahi paʻakikī kahi e ʻike ʻia ai lākou i ka makū, nā kemika, a me nā mea ʻino ʻē aʻe. ʻO ka hopena, hoʻohana pinepine ʻia nā paipu galvanized ERW i nā noi waho e like me ka pā, scaffolding, a me nā ʻōnaehana hoʻohele wai.
(2) Ka ikaika a me ka lōʻihi
ʻO nā paipu galvanized ERW e hōʻike ana i ka paʻa o ka hoʻolālā maikaʻi, e kūpono ana ia no nā noi kiʻekiʻe i nā ʻoihana e like me ka aila a me ke kinoea, ke kūkulu ʻana, a me ka mahiʻai. ʻO ke kaʻina hana kuʻi ʻana o ka uila e hana i nā hui kuʻi ikaika a hiki ʻole ke kū i ka paʻakikī o ka hoʻohana kaumaha. Hoʻohui ʻia, hāʻawi ka galvanized coating i kahi ʻāpana o ka pale ʻana i ka pōʻino kino, e like me nā ʻōpala a me nā abrasions, e hoʻonui hou i ka lōʻihi o nā paipu. ʻO kēia hui pū ʻana o ka ikaika a me ka lōʻihi e hoʻolilo i nā paipu galvanized ERW i koho kūpono no nā papahana ʻoihana koʻikoʻi a me nā noi ʻoihana.
(3) ka uku-pono
ʻOiai ko lākou ʻano maikaʻi, ʻoi aku ka maikaʻi o nā paipu ERW galvanized i hoʻohālikelike ʻia me nā mea paipu ʻē aʻe. ʻO ke kaʻina hana maʻalahi a me ka nui o nā mea waiwai e kōkua i ko lākou hiki ke loaʻa. Eia kekahi, ʻo ko lākou ola lōʻihi a me nā koi haʻahaʻa haʻahaʻa e hopena i ka mālama ʻana i ke kumukūʻai i ke ola o nā paipu. Hoʻolilo kēia i nā paipu galvanized ERW i kumu kūʻai kūpono no nā papahana e koi ana i nā ʻōnaehana paipu kūpaʻa lōʻihi me ka ʻole o ka haki ʻana i ka panakō.
Inā ʻoe ma ka mākeke no ʻO nā paipu kaulahao ERW a ke noʻonoʻo nei i kāu mau koho no nā mea hana, hiki iā ʻoe ke hele i ka Longma Group ma info@longma-group.com. Hiki i kā lākou hui ke hāʻawi i ka ʻike kikoʻī e pili ana i kā lākou ʻano huahana, nā kikoʻī, a pehea e hoʻokō ai kā lākou paipu i kāu mau koi papahana.
