Hiki kepoepoe, huinaha, huinahalike, a i ole ia na ano hana kūikawā e ae.
Kuhi ʻia kēia ʻatikala i nā koi o ASTM A500 no ke kila kila.

Hoʻokaʻawale ʻo ASTM A500 i ka paipu kila i ʻekolu mau papa,papa B, papa C, a me ka papa D.
He mea pono ke hoʻomaopopo ʻia ua loaʻa i nā mana mua o ASTM A500 ka Papa A, i wehe ʻia i ka mana hou o 2023.
Lahi Nui
No nā paipu me ke anawaena o waho ≤ 2235mm [88in] a me ka mānoanoa o ka paia ≤ 25.4mm [1in].
Mea Maka
E hana ʻia ke kila e kekahi a ʻoi aku paha o kēia mau hana.oxygen kumu a i ʻole ka umu uila.
Ke Kaʻina Hana Oxygen Basic: He ala wikiwiki kēia o ka hana kila, e hōʻemi ana i ke kalapona ma ka puhi ʻana i ka oxygen i loko o ka hao puaʻa i hoʻoheheʻe ʻia, ʻoiai e wehe ana i nā mea makemake ʻole e like me ka sulfur a me ka phosphorus.He kūpono ia no ka hana wikiwikiʻana i nā mea kila nui.
Ke Kaʻina Hana Uila Uila: Ke hoʻohana nei ke Kaʻina Hana Uila Uila i kahi kiʻekiʻe wela e hoʻoheheʻe ai i ka ʻōpala a hoʻemi pololei i ka hao, a he mea pono loa ia no ka hana ʻana i nā māka kūikawā a me ka hoʻomalu ʻana i nā haku mele, a me ka hana liʻiliʻi.
Hana Hana
ʻO ke kaʻina hana hoʻoheheʻe ʻole.
E hana ʻia nā paipu welded mai ke kila ʻōwili palahalaha e ke kaʻina uila-kūʻē-weld (ERW).Pono e hoʻopili ʻia ka weld seam e hōʻoia i ka ikaika o ka paipu.
ʻO nā paipu i hana ʻia e ke kaʻina hana kuʻi ʻana, ʻaʻole i wehe ʻia ka weld o loko.

Hiki ke annealed a i ʻole ke kaumaha.
Hoʻokō ʻia ka Annealing ma ka hoʻomehana ʻana i ka paipu i kahi wela kiʻekiʻe a laila hoʻomaha mālie.Hoʻonohonoho hou ʻo Annealing i ka microstructure o ka mea e hoʻomaikaʻi ai i kona ʻano paʻakikī a me ke kūlike.
Hoʻopau ʻia ka hoʻomaha ʻana i ka pilikia ma ka hoʻomehana ʻana i ka mea i kahi haʻahaʻa haʻahaʻa (ʻoi aku ka haʻahaʻa ma mua o ka annealing) a laila hoʻopaʻa ʻia no kekahi manawa a laila hoʻomaha.Kōkua kēia i ka pale ʻana a i ʻole ka haki ʻana o ka mea i ka wā o nā hana ma hope e like me ka wili a ʻokiʻoki.

Mea hoʻolālā kikoʻī: ASTM A500, ʻaʻole pono e hoʻokomo i ka makahiki o ka paʻi ʻana.
Palapala Papa: Papa B, C a i ole D.
No nā paipu hana ≤ 100mm (4in) ke anawaena, hiki ke hoʻohana ʻia nā lepili e hōʻailona i ka ʻike ʻike maopopo.
Nā noi o ASTM A500
Ma muli o kāna mau waiwai mechanical maikaʻi loa a me ka weldability, hoʻohana ʻia ka paipu kila ASTM A500 i nā ʻano hana like ʻole kahi e pono ai ka lōʻihi a me ka ikaika.
Kūkulu: Hoʻohana ʻia no ke kākoʻo ʻana i nā hale kūkulu hale e like me nā ʻōnaehana hoʻoheheʻe, nā hale kūkulu hale, nā mea hoʻolālā arch, a me nā kolamu poepoe.
Kapili alahaka: No nā mea hana o nā alahaka, e like me nā kolamu haʻahaʻa pōʻai a me nā pahu no nā alahaka.
ʻOihana ʻenehana: Ma na hale hana nui e like me ka aila a me ke kinoea, na mea kanu kemika, a me na wili kila, hoohanaia na paipu kila poepoe no ke kukulu ana i na hale kokua a me ka paipu paipu.
Pūnaehana hoʻokele: No nā pou hōʻailona kaʻaahi, nā kia kukui, a me nā kuʻi kiaʻi.
Mea hana mīkini: Ma ke ʻano o nā mīkini a me nā mea kaumaha, e like me nā mīkini mahiʻai, nā mea hana mining, a me nā mīkini hana.
Nā pono hana: Hoʻohana ʻia i nā paipu no ka wai, ke kinoea, nā huahana ʻaila, a me nā mea ʻē aʻe, a ma ke ʻano he paipu pale uea a me ke kaula.
Nā hale haʻuki: I ke kūkulu ʻana i nā wahi haʻuki, hoʻohana ʻia nā paipu kila poepoe e hana i nā bleachers, nā hale kiaʻi kukui, a me nā hale kākoʻo ʻē aʻe.
Nā lako a me nā mea hoʻonani: Hoʻohana ʻia nā paipu kila ʻōpuni no ka hana ʻana i nā lako metala, e like me nā wāwae no nā papaʻaina a me nā noho, a me nā mea hoʻonaninani no ka hoʻolālā kūloko hou.
ʻO ka pā a me nā ʻōnaehana ala: Hoʻohana ʻia ma ke ʻano he pou no ka pā a me nā ʻōnaehana railing, ʻoi aku ka ikaika o ke kūkulu ʻana a me ka lōʻihi.
Nā Mea Hana ʻē aʻe o ASTM A500
ASTM A501: He mea maʻamau kēia no ka hoʻoheheʻe ʻana i ke kila kalapona wela, e like me ASTM A500, akā pili i ke kaʻina hana hana wela.
ASTM A252: Kūlana no nā puʻu paipu kila no ka hoʻohana ʻana i ka hana paʻa a me ka hana pila.
ASTM A106: Paipu kila kalapona ʻole, hoʻohana maʻamau i nā wahi wela kiʻekiʻe.
ASTM A53: ʻO kekahi ʻano paipu kila kalapona no ke kaomi a me nā noi mechanical, hoʻohana nui ʻia i nā ʻōnaehana hoʻoili wai.
EN 10210: Ma ʻEulopa, ʻo ka maʻamau EN 10210 e kuhikuhi i nā kūlana hāʻawi ʻenehana no nā ʻāpana hollow structural hollow wela, aia nā wahi noi like me ASTM A500.
CSA G40.21: He maʻamau Kanada e hāʻawi ana i kahi ākea o nā kila maikaʻi o ke kūkulu ʻana i nā ʻano o nā māka ikaika e hiki ke hoʻohana ʻia no nā noi like.
JIS G3466: Japanese Industrial Standard no na paipu huinaha a me ka huinahalike o ke kila kalapona no ka hoohana ana i ka hana ma'amau.
IS 4923: Indian Standard no ke anu-hana welded a seamless carbon steel structural hollow pauku.
AS/NZS 1163: Nā kūlana o Australian a me New Zealand no nā paipu kila a me nā ʻāpana hollow.
ʻO kā mākou huahana pili
Mai kona hoʻokumu ʻia ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako paipu kila kila ma Northern China, i ʻike ʻia no kāna lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hāʻina piha.ʻO ka laulā huahana nui o ka hui e pili ana i nā paipu kila maʻemaʻe, ERW, LSAW, a me SSAW, a me nā paipu paipu, nā flanges, a me nā kila kūikawā.
Me ka paʻa ikaika i ka maikaʻi, hoʻokō ʻo Botop Steel i nā mana koʻikoʻi a me nā hoʻāʻo e hōʻoia i ka hilinaʻi o kāna mau huahana.Hāʻawi kāna hui ʻike i nā hāʻina pilikino a me ke kākoʻo loea, me ka nānā ʻana i ka ʻoluʻolu o ka mea kūʻai aku.
