ASTM A179paipu kila kalapona huki anuHoʻohana nui ʻia i nā ʻāpana like ʻole o nā hale hana metala, ʻoi loa ma hope o ka ʻōpala o nā ʻāpana kila i hoʻokomo ʻia i 440 ~ 460℃ka hoʻoheheʻe ʻana i ka zinc solution, i hoʻopili ʻia ka ʻili kila i ka papa zinc, e pāʻani ana i kahi kumu mālama.He ala maikaʻi kēia o ka corrosion metala, ʻo ka hoʻohana ʻana i nā hiʻohiʻona nui penei:

(1) ASTM A179 nā mea hana paipu maʻemaʻe me ka mānoanoa ʻoʻoleʻa o ka zinc layer i uhi ʻia i ka ʻili o ke anu, hiki iā ia ke pale i ka matrix seamless tube matrix a me kekahi pilina me ka hopena corrosion e pale i ka matrix kila mai ka ʻino.I ka lewa maʻamau, ʻo ka ʻili o ka papa zinc e hana i kahi papa o ka ʻili o ka zinc oxide lahilahi a paʻakikī, paʻakikī ke hoʻoheheʻe i ka wai, no laila ke pāʻani nei ka matrix kila i kahi hana pale.Inā hoʻopuka ka zinc oxide a me nā mea ʻē aʻe o ka lewa i ka paʻakai zinc insoluble, ʻoi aku ka makemake o ka hopena anti-corrosion.

(2) Me ka hao - zinc alloy layer, i hui pū ʻia me ka mānoanoa, a me ka anti-corrosion kū hoʻokahi i ka lewa moana a me ka lewa lewa.

(3) ASTM A179 i huki ʻia i ke anu anu me ke kūpale ikaika ma muli o ka hui pū ʻana o ka paʻa, zinc - hao miscible.

(4) No ka maikaʻi o ka ductility o ka zinc, ua hoʻopili ʻia kona ʻāpana paʻa a me ke kumu kila i kahi paʻa, no laila hiki i nā ʻāpana wela ke anuanu, ʻōwili, kaha kiʻi, kulou a me nā ʻāpana ʻē aʻe me ka ʻole o ka pōʻino i ka uhi.

(5) Hot-dip galvanized structural steel pipe, ka like me ka annealing treatment, hiki ke hoʻomaikaʻi maikaʻi i nā waiwai mechanical o ka matrix kila e hoʻopau i ke koʻikoʻi hoʻoheheʻe ʻana i ke kila, ua kūpono i ka hale kila no ka huli ʻana.

(6) ʻO ka ili o ke anu i huki ʻia i ka paipu liʻiliʻi ma hope o ka galvanized wela he mālamalama a nani.

(7) ʻO ka papa zinc maʻemaʻe ka papa galvanized wela loa o ka papa galvanized, kokoke loa kona ʻano i ka zinc maʻemaʻe, me ka ductility, no laila ua piha i ka maʻalahi.
