Paipu galvanized kūikawā no ka puka
ʻO ka wehewehe pōkole:
ʻO ka paipu galvanized, i ʻike ʻia ʻo galvanized steel pipe, ua māhele ʻia i ka galvanizing hot-dip a me ka electro galvanizing.He mānoanoa ka papa galvanizing wela a loaʻa iā ia nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.He haʻahaʻa ke kumukūʻai o ka electro galvanizing, ʻaʻole maʻalahi ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka paipu galvanized wela.
Hot dip galvanized steel pipe
Hiki ke hoʻololi kino a me ke kemika paʻakikī ma waena o ka matrix paipu kila a me ka hoʻoheheʻe hoʻoheheʻe hoʻoheheʻe ʻia e hana i kahi papa zinc ferroalloy kūpaʻa i ka corrosion me ka hana paʻa.Hoʻohui ʻia ka papa ʻaina me ka ʻāpana zinc maʻemaʻe a me ka matrix paipu kila.No laila, ua ikaika ka corrosion kū'ē.
Ma hope o ka hoʻomohala ʻana mai ka makahiki 1960 a hiki i ka makahiki 1970, ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka huahana o ka paipu kila galvanized wela.Mai 1981 a i 1989, ua helu mau ʻia ʻo ia ma ke ʻano he huahana kiʻekiʻe o ka Ministry of metallurgy a me ka makana kālā aupuni.Ua hoʻonui pū ʻia ka huahana no nā makahiki he nui.ʻOi aku ka huahana ma mua o 400000 tons ma 1993 a ʻoi aku ma mua o 600000 tons ma 1999. Hoʻokuʻu ʻia i ka Hikina Hema o Asia, ʻApelika, ʻAmelika Hui Pū ʻIa, Iapana, Kelemānia a me nā ʻāina a me nā ʻāina ʻē aʻe.Hoʻohana nui ʻia nā paipu galvanized wela e like me nā paipu hoʻoili wai a me nā paipu kinoea, me nā kikoʻī maʻamau o + 12.5 ~ + 102 mm.Mai ka 1990s, ma muli o ka nānā ʻana o ka mokuʻāina i ka mālama ʻana i ke kaiapuni a me ka ʻoi aku ka paʻakikī o ka mālama ʻana i nā ʻoihana haumia kiʻekiʻe, ʻo nā "ʻekolu ʻōpala" i hana ʻia i ka hana ʻana i nā paipu galvanized wela he paʻakikī ke hoʻoponopono, hui pū me ka hoʻomohala wikiwiki ʻana o ka stainless. kila welded paipu, PVC paipu a me composite paipu, a me ka paipai 'ana i nā mea hale kemika a me ka palena o ka hoʻohana' ana i ka galvanized kila paipu, Ka ulu ana o ka wela-hoʻopuʻu galvanized welded paipu ua nui kapu a kaupalena, a me ka ulu ana o ka wela. - ua lohi ka paipu welded dip galvanized.
Paipu kila galvanized anu
ʻO ka papa zinc he papa electroplating, i hoʻokaʻawale ʻia mai ka matrix pipe 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 wai.
