ʻAmelika Hui Pū ʻIa ASTM A588 Corten Steel Plate Piling and Structural Steel Truss Bridge

Hoʻopili ʻo ASTM A588 i nā ʻano kila haʻahaʻa haʻahaʻa haʻahaʻa kiʻekiʻe, nā papa, a me nā kaola no ka welded, riveted, a i ʻole ke kūkulu ʻia ʻana akā i manaʻo ʻia no ka hoʻohana ʻana i nā alahaka welded a me nā hale kahi mea nui e mālama ai i ke kaumaha a i ʻole ka lōʻihi.

ʻO ka ASTM A588 kahi kaha kiʻekiʻe kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka ikaika kiʻekiʻe a me ka hoʻomaikaʻi ʻana i ke kūpaʻa corrosion o ka lewa no nā ʻano kila kila e like me nā kihi, ke kahawai a me nā kaola, a me ka pā kila a me nā kaola.Hoʻohana nui ʻia ʻo ASTM A588 no:
Alahaka hele wāwae
Alahaka Alahaka Alahaka a me na mea e ae
Kapili moku
Nā pahu pahu
Nā Kaʻa Kaʻa a me nā ipu
Paʻa pā
Nā kiʻi kiʻi

Hoʻohana nui ʻia ka ʻōlelo kikoʻī A588 no ka hoʻohana ʻana i nā noi i pena ʻole ʻia, kahi mea nui ka mālama ʻana i ke kaumaha a i ʻole ka lōʻihi o ke ola ʻana ma muli o kona mau waiwai pale a / a i ʻole e loaʻa i kahi hiʻohiʻona nani.

ʻOi aku ka maikaʻi o ke kūpaʻa ʻino o ka lewa o A588 ma mua o nā kila kalapona e like me A36 a me A572-50 me ka hoʻohui keleawe a i ʻole.Ke hoʻolālā maikaʻi ʻia a hōʻike ʻia i ka lewa, kūpono ʻo A588 no nā noi he nui i ke ʻano i pena ʻole ʻia.

Loaʻa iā ASTM A588 he 50ksi liʻiliʻi ka ikaika a me ka ikaika tensile liʻiliʻi he 70ksi.

Hoʻokaʻawale:
1. Ke kila welu kiʻekiʻe
ʻO ke kila kiʻekiʻe ke kū'ē i ka wā e hoʻohui i kahi liʻiliʻi o ke keleawe, phosphorus, chromium, a me nā mea nickel i ke kila e hana i kahi pale pale ma ka ʻili o ka hui metala e hoʻomaikaʻi i ka hana o ke kila e kū'ē i ka ʻino o ka lewa.Hiki iā ʻoe ke hoʻohui i kahi liʻiliʻi o ka molybdenum, niobium, Elements e like me vanadium, titanium a me zirconium hiki ke hoʻomaʻemaʻe i ka palaoa, hoʻomaikaʻi i nā waiwai mechanical o ke kila, hoʻomaikaʻi i ka ikaika a me ka paʻakikī o ke kila, hoʻemi i ka mahana hoʻololi brittle, a loaʻa iā ia. ʻoi aku ka maikaʻi o ka pale ʻana i ka haki ʻana.
2. ʻO ke kila hoʻoheheʻe no ka hoʻoheheʻe ʻana
ʻO nā mea i hoʻohui ʻia i ke kila kila, koe wale nō ka phosphorus, ua like nō ia me nā kila kila kiʻekiʻe e kū nei i ka wā, a ua like kā lākou mau hana a hoʻomaikaʻi i ka hana kuʻi.

Nā hiʻohiʻona:

ʻO ke kila weathering nā hiʻohiʻona o ka paʻakikī, ka paʻa ʻana o ka plastic, ka hoʻokumu ʻana, ka kuʻi ʻana a me ka ʻoki ʻana, ke kūpaʻa ʻana, ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa luhi o ke kila kiʻekiʻe;ʻO ke kūpaʻa o ka wā he 2-8 mau manawa ma mua o ke kila kalapona maʻamau, a ʻo ka hana o ka uhi ʻana he 1.5 o ke kila kalapona maʻamau.-10 mau manawa, ʻo 1.5-10 mau manawa ka hoʻokō ʻana o ke kila kalapona maʻamau, hiki ke hoʻohana ʻia no ka uhi ʻana i ka lahilahi, ka uhi ʻole a i ʻole ka hoʻopili maʻalahi.Loaʻa i kēia kila nā hiʻohiʻona o ka anti-rust, corrosion resistance, lōʻihi ke ola, thinning a me ka hoʻemi ʻai ʻana, mālama hana a mālama i ka ikehu, e pōmaikaʻi ana i nā mea hana a me nā mea hoʻohana.ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion i ka lewa.Hiki ke hoʻoheheʻe ʻia, hōʻike ʻia a pena wale ʻia paha ke kila welu.ʻO ka ʻōnaehana kila me ka pale ʻana i ka corrosion, hoʻolōʻihi i ke ola, mālama i ka hana, hoʻemi i ka hoʻohana ʻana a me ka hoʻomaikaʻi ʻana he ʻano hana hou, ʻenehana hou a me nā kaʻina hana hou e hiki ke hoʻohui ʻia i ka metallurgy hou, i hiki ke hoʻomau i ka hoʻomohala ʻana a me ka hana hou.Pūnaehana kila.

Pono:

Hana ʻia ke kila weathering me ke kila kalapona maʻamau me kahi mea liʻiliʻi o nā mea ʻino e like me ke keleawe a me ka nickel.Loaʻa iā ia nā hiʻohiʻona o ka ikaika kila, ductility, hana, welding, abrasion, kiʻekiʻe wela, luhi, etc.;ʻO ke kūpaʻa o ka wā he 2 ~ 8 o ke kila kalapona maʻamau ʻO ka hana hoʻopiʻi ʻana he 1.5 ~ 10 mau manawa o ke kila kalapona maʻamau, hiki ke hoʻohana ʻia i ka uhi ʻoi aku ka lahilahi, ʻole a maʻalahi paha.Loaʻa i ke kila nā hiʻohiʻona o ka pale ʻana i ka ʻōpala, ka pale ʻana i ka corrosion a me ka lōʻihi o nā ʻāpana, ka hoʻemi ʻana a me ka hoʻemi ʻai ʻana, a me nā hiʻohiʻona mālama hana a mālama i ka ikehu, e pōmaikaʻi ai nā mea hana a me nā mea hoʻohana.

Noi:

ʻOi aku ka maikaʻi o ka hoʻohana ʻana i ke kila kūpaʻa kiʻekiʻe ma mua o ke kila kūʻē i ka wā no ka hale welded ma muli o kona kūpaʻa corrosion o ka lewa.Hoʻohana nui ia no ka bolting, riveting a me ka welding structural parts no nā kaʻa, nā ipu, nā hale, nā hale kiaʻi a me nā hale ʻē aʻe.Ke hoʻohana ʻia e like me nā ʻāpana welded structural, ʻaʻole pono ka mānoanoa o ke kila ma mua o 16mm.ʻOi aku ka maikaʻi o ka hana kuʻi ʻana o ke kila hoʻoheheʻe ʻia no ka hale welded ma mua o ke kila kiʻekiʻe, a hoʻohana nui ʻia no nā ʻāpana hana welded no nā alahaka, nā hale a me nā hale ʻē aʻe.
