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 kumu o ka papahana hale ʻōmaʻomaʻo, pono nā mea e hoʻomalu 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 papahana 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. Hoʻohui ʻia ka papa ʻaina me ka ʻāpana zinc maʻemaʻe a me ka matrix pipe kila. No laila, he ikaika ka corrosion kū'ē.

2. Hoʻoponopono ʻia ke kaʻina hana o ka paipu galvanized galvanized: hoʻoponopono i ke kaʻina hana o ka paipu galvanized. ʻO ka mua, e ʻohi ʻia ke kila hao i hoʻohana ʻia no ka hana ʻana i ka paipu no ka wehe ʻana i ka hao 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 maikaʻi o kona pale ʻana i ka corrosion ma mua o ka paipu galvanized hot-dip
