Nūhou - ASTM A992 vs ASTM A572 Papa 50: Ke kila kūkulu maikaʻi loa no nā papahana kūkulu ʻAmelika Hui Pū ʻIa, Kanada a me ʻAmelika Hui Pū ʻIa

Me ka ulu nui ʻana o ka hoʻopukapuka kālā ʻana ma nā ʻoihana pono hana, ka ulu ʻana o nā ʻoihana, a me ka ʻoihana hale kūʻai ma ʻAmelika ʻĀkau, ua lilo ke koho ʻana i ke kila kūkulu kūpono i mea nui i ka hōʻoia ʻana i ka palekana o ka papahana, ka pono o ke kumukūʻai, a me ka hana lōʻihi.

Ke kila kūkulu e kūlike ana meASTM A992 (nā kaola flange ākea)a meASTM A572 (nā papa a me nā ʻaoʻao) Papa 50ʻo ia ke kila kūkulu i hoʻohana nui ʻia e nā ʻenekinia, nā mea hana ʻaelike, a me nā mea nona ka papahana ma ʻAmelika Hui Pū ʻIa a me Kanada.

Akā, ʻo wai ke ʻano kila i kūpono loa no kāu hale kūʻai, hale hana, alahaka, kikowaena logistics, a i ʻole papahana hale kalepa e hiki mai ana?

No ke aha ʻo ASTM A992 ke koho makemake ʻia no nā hale kila kila

Ua lilo ʻo ASTM A992 i mea maʻamau no nā W Beams (Nā Kaula Flange Laulā) i hoʻohana ʻia i ke kūkulu ʻana i nā hale kila hou ma ʻAmelika ʻĀkau.

ʻO nā pono nui:

ʻOi aku ka ikaika o ka hua o 50 ksi
Hana maikaʻi loa i ka weldability a me ka hana hana
Nā waiwai mechanical kūlike
Hoʻomaikaʻi ʻia ke kūpaʻa seismic
Hoʻonohonoho pono ʻia no nā kiʻi hale kila a me nā hale kiʻekiʻe

Ma muli o kēia mau pono, hoʻohana nui ʻia ʻo ASTM A992 i:

Nā hale kūʻai hana kila
Nā hale hana ʻoihana
Nā hale hana hana
Nā kikowaena hoʻolaha
Nā hale kalepa
Nā hale kila he nui nā papa

No nā papahana e pono ai nā mōlina kila ākea nui a me nā papa hana kūkulu wikiwiki, hāʻawi pinepine ʻo ASTM A992 i ke kaulike maikaʻi loa ma waena o ka ikaika a me ka pono o ka hana ʻana.

Ke hāʻawi aku nei ʻo ASTM A572 Grade 50 i ka waiwai nui aʻe

Papa ASTM A572 50he kila kūkulu haʻahaʻa ikaika kiʻekiʻe i ʻike ʻia no kona ʻano maʻalahi a me ka lakio ikaika-a-kaumaha maikaʻi loa.

Ke hoʻohālikelike ʻia me nā papa kila kalapona maʻamau, ʻae ʻo ASTM A572 Grade 50 i nā ʻenekinia e hōʻemi i ke tona kila me ka mālama ʻana i ka hana kūkulu.

ʻO nā noi kaulana e komo pū ana me:

Nā alahaka alanui nui
Nā alahaka kaʻaahi
Nā papahana ʻoihana
Nā hale kiaʻi hoʻoili
Nā hale hana ʻoihana kaumaha
Nā hale awa a me nā hale moana

No nā papahana i hōʻike ʻia i nā kūlana ukana kiʻekiʻe a i ʻole e koi ana i nā hoʻolālā kūkulu māmā, hiki i ka ASTM A572 Grade 50 ke hāʻawi i ka mālama kālā nui.

Ke hoʻohālikelike nei iā ASTM A992 a me ASTM A572 Papa 50

ʻOiai ʻo nā papa ʻelua e hāʻawi i ka ikaika hua liʻiliʻi loa he 50 ksi, ʻokoʻa kā lākou hoʻohana i manaʻo ʻia.

ASTM A99Ua hoʻomohala kūikawā ʻia ʻo 2 no nā Wide Flange Beams a me ke kūkulu hale ʻana, ʻo ia ke koho makemake nui ʻia no nā hale kūʻai kila, nā hale kalepa, a me nā hale ʻoihana.

Papa ASTM A572 50, i kēia manawa, hāʻawi i ka maʻalahi nui aʻe ma waena o kahi ākea o nā noi kūkulu, ʻoiai hoʻi i nā alahaka, nā ʻoihana pono, a me nā papahana ʻenekinia kaumaha.

No nā papahana he nui o ʻAmelika ʻĀkau, hoʻohui pinepine nā ʻenekinia i nā mea ʻelua i loko o hoʻokahi hale e hoʻonui i ke kumukūʻai a me ka hana.

Ke ulu nei ke koi ma nā ʻāina ʻAmelika

Hōʻike nā ʻano kūkulu hale hou i ka koi nui no:

Nā Kaula Flange ākea ASTM A992
Nā Papa Kila ASTM A572 Papa 50
Nā kukuna H
Nā Kukui W
Nā ʻĀpana Kila Kūkulu
Nā Hale Hana Kila
Nā Hana Kila i Hana mua ʻia
Nā Hale Kūʻai kila
Nā Hale Kila ʻOihana
Ke kila kūkulu alahaka

I ka hoʻomau ʻana o nā aupuni i ka hoʻopukapuka kālā ʻana i ka halihali, ka logistics, ka hana ʻana, a me nā ʻoihana ikehu, e manaʻo ʻia e ikaika mau ana ke koi no nā huahana kila kūkulu i hōʻoia ʻia ma ʻAmelika Hui Pū ʻIa, Kanada, Mekiko, ʻAmelika Waena, a me ʻAmelika Hema.

Kākoʻo ʻo Royal Steel Group i nā Papahana Kūkulu ʻAmelika ʻĀkau

Ma ke ʻano he mea hoʻolako honua alakaʻi o ke kila kūkulu a me nā hoʻonā kūkulu kila,Pūʻulu kila aliʻiHāʻawi i nā lawelawe hoʻolako lako a me nā lawelawe hana no nā mea hana ʻaelike, nā ʻoihana EPC, nā mea hana, a me nā mea hoʻomohala ma nā ʻAmelika āpau.

Hāʻawi ʻo Royal Steel Group i kēia mau mea:

Nā Kaula Flange ākea ASTM A992
Nā Papa Kila ASTM A572 Papa 50
Nā Kukui H a me nā Kukui I
Nā Kahawai UPN a me nā Kahawai C
Nā Puʻu Pepa Kila
Nā Puʻu Paipu Kila
Nā ʻāpana hana kila i hana mua ʻia
Hana Hana Kūkulu Kila i Hoʻopilikino ʻia

Me kahi kaulahao hoʻolako i hoʻohui ʻia, nā hale hana kila ʻoihana, nā ʻōnaehana kaohi maikaʻi koʻikoʻi, a me ka ʻike hoʻokuʻu aku nui, kōkua ʻo Royal Steel Group i nā mea kūʻai aku e hōʻemi i nā kumukūʻai kūʻai, hoʻopōkole i nā papa hana hoʻouna, a hōʻoia i ka mālama ʻana i nā kikoʻī o ka papahana ʻAmelika ʻĀkau.

Ke koho ʻana i ka hoa kila kūkulu kūpono

Inā paha e pili ana kāu papahana i kahi hale kūʻai ma Texas, kahi kikowaena logistics ma Kanada, kahi alahaka ma ʻAmelika Waena, a i ʻole kahi hale ʻoihana ma ʻAmelika Hema, ʻo ke koho ʻana i ke kila kila kūpono a me ka mea hoʻolako he mea nui ia no ka holomua o ka papahana.

No nā papahana kūkulu hale a me nā papahana kūkulu kila, ʻo ASTM A992 ke kūlana kiʻekiʻe o ka ʻoihana. No nā noi ʻenekinia a me nā ʻoihana ʻenekinia kaumaha, ke hāʻawi mau nei ke kila ASTM A572 Grade 50 i ka waiwai kūikawā.

Ma ka hui pū ʻana me nā mea hoʻolako akamai e like me Royal Steel Group, hiki i nā mea nona ka papahana ke hoʻopaʻa i nā huahana kila kūkulu kiʻekiʻe, nā papa hana hoʻouna hilinaʻi, a me ke kākoʻo loea piha e uhi ana i ʻAmelika holoʻokoʻa.

Kaomi ma lalo e kūkākūkā i nā kikoʻī o ka papahana.
