ʻO ke kūpaʻa ʻino o ka paipu kila galvanized ma Kina
No ka mea, ʻo ka paipu kila wela wela, ua kiʻekiʻe loa ka nui o ka galvanized. ʻOi aku ka mānoanoa awelika o ka papa galvanized ma mua o 65 microns, a ʻokoʻa loa kona kūpaʻa corrosion mai ka paipu galvanized wela. Ua ʻae ʻia nā mea hana paipu galvanized maʻamau e hoʻohana i nā paipu galvanized anuanu e like me nā paipu wai a me ke kinoea. ʻO ka papa galvanized o ke anuanu o ka paipu kila he mea electroplating, a ua hoʻokaʻawale ʻia ka papa zinc mai ka substrate paipu kila. He lahilahi ka papa zinc, a ua hoʻopili wale ʻia ka papa zinc i ka matrix pipe kila, kahi maʻalahi e hāʻule. No laila, ʻilihune kona pale ʻana i ka corrosion. I nā hale hou, pāpā ʻia ka hoʻohana ʻana i nā paipu kila galvanized anuanu e like me nā paipu kila wai. Ma hope o ka ʻohi ʻana, hoʻomaʻemaʻe ʻia nā paipu kila maʻemaʻe API i loko o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia me ka pahu wai wai. I mea e hōʻoia ai i ka maikaʻi, ʻaʻole hoʻohana ʻia ka electro galvanizing (cold plating). ʻO kēlā mau ʻoihana liʻiliʻi wale nō me ka liʻiliʻi liʻiliʻi a me nā mea kahiko e hoʻohana i ka electro galvanizing, ʻoiaʻiʻo, ʻoi aku ka maʻalahi o kā lākou kumukūʻai. Ua kāpae ʻia ke Kuhina o ke kūkulu ʻana i ka paipu galvanized i hope, ʻaʻole ia e hoʻopili ʻia i ka electro galvanized i ka wā e hiki mai ana. ʻO ia ka hana ʻana o ka metala hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi papa paʻa, i hui pū ai ka matrix a me ka uhi. ʻO ka hoʻoheheʻe wela wela, ʻo ia ka ʻohi ʻana i ka paipu kila ma mua, i mea e wehe ai i ka ʻokikene hao ma ka ʻili o ka paipu kila, a laila e hoʻouna i ka pahu galvanizing wela. Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi. 1. Medium plate unit: hana nui ia i na papa laula a manoanoa no ka hana ana i na paipu wiliwili arc longitudinal submerged. ʻO nā paipu welded arc longitudinal i hoʻohana nui ʻia i ka laina nui o ka aila a me ke kinoea hoʻoili kiʻekiʻe.
ʻO ka Mille Steckel:Loaʻa i ka mill Steckel kahi wili wili a me ka 4-kiʻekiʻe reciprocating wili hoʻopau. Hoʻokomo ʻia ʻelua wili wela wela ma nā laina conveyor ma nā ʻaoʻao ʻelua o ka wili hoʻopau. Hoʻokomo pinepine ʻia ka papa ʻaina hoʻoheheʻe i kahi ʻōnaehana hoʻoluʻu laminar a me kahi keʻena wili. Ma ka wili steckel, ka moʻolelo thermomechanical o ka lōʻihi holoʻokoʻa o ke kila kuʻekuʻe kuʻekuʻe paipu e hoʻololi nui ʻia, ʻoi aku ka nui o ka hana ʻana o ka micro stainless steel stamping elbow pipe fittings, ka mea e hoʻopilikia ikaika i ka degere recrystallization, ka ulu ʻana o ka palaoa a me ka ua ma ka hoʻopau ʻana. wili, a alakaʻi i nā hoʻololi nui i ka microstructure hope loa a me nā waiwai o ka lōʻihi holoʻokoʻa o ke kila kuʻekuʻe kuʻekuʻe paipu.
Hale mīkini Semi mau:me 1 wili Steckel a me 5 wili hoopau. Ma kahi wili wili mau, ʻo ka ʻōwili wela o nā mea paipu i ka hoʻopau ʻana i nā ala paʻa mau loa mai kekahi ʻaoʻao a i kekahi. ʻOi aku ka liʻiliʻi o ka manawa ma waena o ka wili hoʻopau ma mua o 3S.
ʻO ka hoʻolei ʻana a me ka ʻōwili mau ʻana o CSP:no ke kila manganese kalapona haʻahaʻa i loaʻa ka niobium, vanadium a me ka titanium composite Microalloying ma ka laina hana CSP, ʻo ka ʻōwili ʻia ʻana kūpono, ka hoʻoluʻu ʻana a me nā kaʻina hana coiling hiki ke hōʻoia i ka hoʻokō ʻana o nā pono mechanical a me ka microstructure o nā paipu paipu i nā koi ʻenehana o ka X60 stainless steel stamping kuʻekuʻe. ka ulu ʻana o nā mea hoʻoheheʻe kuʻekuʻe lima o kēia wā. Ua hoʻomohala ʻo China CSP i ka hoʻolei ʻana a me ka laina hana ʻōwili i ka X60 stainless steel stamping elbow fittings, aʻo nā mea hana CSP ʻē aʻe ma ʻAmelika Hui Pū ʻIa a me nā ʻāina ʻē aʻe i hoʻomohala a hana i nā kiʻekiʻe kiʻekiʻe stainless steel stamping elbow fittings X60, X65 a me X70. ʻO ka hiʻohiʻona o ke kaʻina hana ʻo ia ka hoʻokaʻawale waena i ka hoʻolei mau ʻana i ka pā lahilahi. ʻO ka hoʻopau ʻia ʻana o ka hoʻokaʻawale kikowaena i ka hoʻolei mau ʻana i ka pā lahilahi e ka galvanized seamless steel pipe ka pilikia ʻenehana nui e hoʻomaikaʻi hou ai i ka maikaʻi o nā mea kuʻekuʻe kuʻekuʻe kila. ʻO nā papa i hoʻohana ʻia no ka kuʻekuʻe kila kila i hoʻohana nui ʻia ʻo A3 a me 16Mn i hana ʻia e Angang a me nā mea hana ʻē aʻe i nā makahiki 1960 a me 1970. Me ka piʻi ʻana o ke anawaena paipu a me ke kaomi hoʻouna ʻana, ʻaʻole hiki i ka ikaika o ka pā paipu paipu ke hoʻokō i nā koi. Ma hope o nā makahiki 1980, ua hoʻomaka nā ʻāpana ʻāpana paipu a pau i hoʻohana i nā papa kila pipeline i hana ʻia e like me nā kūlana API ʻAmelika. I kēlā manawa, ma muli o ka ʻenehana ʻokoʻa o nā mea hana kīʻaha kuʻekuʻe kuʻekuʻe i loko o ka hale, ua hoʻohana nui ʻia nā papa i lawe ʻia mai.
