Me ka holomua mau o ke kaiāulu, ʻaʻole hiki i ke ʻano hana mahiʻai kuʻuna ke hoʻokō i nā pono o ka hoʻomohala ʻana o ka moʻomeheu hou, a ʻimi ʻia ka ʻoihana mahiʻai hou e nā poʻe o ka ʻoihana.ʻO ka ʻoiaʻiʻo, ʻo ka mea i kapa ʻia ʻo nā mea mahiʻai he mau hale ʻōmaʻomaʻo.ʻAʻole i kaupalena ʻia e ka manawa a me ka lewa.Hiki iā ia ke hana i ka mahiʻai ma nā wahi kūikawā e like me ka pāpū, mauna hohonu a me ka wao nahele.Ma ke ʻano he kumu o ka pāhana hale ʻōmaʻomaʻo, pono e mālama nā mea i ka maikaʻi o ka papahana, ʻo ka mea mua, mai ke koho ʻana i nā mea.Eia kekahi laʻana, no nā mea kila i hoʻohanaʻia i loko o ka hale kōmaena, e hanaʻia a hoʻopauʻia ke kila kiʻekiʻe.Ma hope o ka hoʻopaʻa ʻana i kahi mea kanu galvanizing ʻoihana, e hoʻāʻo hou ka ʻoihana nānā maikaʻi.Ma hope o ka hala ʻana i ka hoʻāʻo, e lawe ʻia i ke kahua kūkulu no ka hoʻohana ʻana.

1. Hot dip galvanized steel pipe structure: hot dip galvanized pipe is to make molten metala react with hao matrix to produce alloy layer, so as to combin the matrix and coating.ʻO ka paipu galvanized hot-dip i hoʻolako ʻia e Tianjin Feilong Pipe Co., Ltd.I mea e wehe ai i ka hao oxide ma ka ʻili o ka paipu kila, ma hope o ka pickling, ua hoʻomaʻemaʻe ʻia 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 i ka pahu wai wai, a laila hoʻouna ʻia 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.ʻO ka matrix o ka paipu kila hoʻoheheʻe wela he paʻakikī ke kino a me ka hopena me ka hoʻoheheʻe hoʻoheheʻe ʻia e hoʻokumu i kahi papa zinc ferroalloy paʻakikī me ka hana paʻa.Hoʻohuiʻia ka papa'āpana me ka'āpana zinc maʻemaʻe a me ka matrix paipu kila.No laila, he ikaika ka corrosion kū'ē.

2. Ka hoʻolālā ʻana o ka paipu kaula hao: hoʻoponopono ka paipu galvanized i ke kaʻina hana o ka paipu galvanized wela.ʻO ka mea mua, e ʻohi ʻia ke kila hao i hoʻohana ʻia no ka hana ʻana i ka paipu no ka wehe ʻana i ka oxide hao ma luna o ka ʻili o ke kila.A laila maloʻo ka ea a hana i ka paipu.He ʻano like ʻole ka uhi ʻana, a he liʻiliʻi ka nui o ka zinc plating, ʻoi aku ka haʻahaʻa ma mua o ke kumukūʻai o ka hana ʻana i ka paipu galvanized wela.ʻOi aku ka ʻino o kona pale ʻana i ka corrosion ma mua o ka paipu galvanized hot-dip
