Kapangidwe ka Chitsulo ka ASTM A992, A572, A283, A913: Kusiyana Kwakukulu mu Msika Wadziko Lonse wa Kapangidwe ka Chitsulo

Masiku ano, kusankha mtundu woyenera wa chitsulo ndikofunikira kwambiri pa umphumphu wa kapangidwe kake, kupanga, ndi mtengo wonse wa ntchito yomanga. Malinga ndi miyezo ya ku America pali mitundu inayi yofanana ya chitsulo.zitsulo zomangira ASTM A992, A572, A283 ndi A913Chitsulo chilichonse chili ndi magawo osiyanasiyana a magwiridwe antchito ndi zofunikira pa polojekiti.

Kusiyana kwa Zinthu ndi Makina

ASTM A992
Gulu: Chitsulo chomangira champhamvu kwambiri (HSLA)
Kupsinjika kochepa: 345 MPa (50 ksi) mphamvu yotulutsa
Khalidwe: Kapangidwe ka "wopanga weld ndi zinthu zogwiritsidwa ntchito zokhudzana ndi kupsinjika" kamayendetsedwa bwino kuti zitsimikizire kuti zimagwirizana bwino komanso zolimba.
Fomu Yaikulu: Yopangidwira makamaka flange yozungulira yotentha (W/H beam).
A992 ndi chitsulo cholimba kwambiri ku North America chomwe chimapangidwa kuti chigwiritsidwe ntchito popanga chitsulo cha chimango.

ASTM A572
Gulu: Chitsulo cholimba champhamvu kwambiri (HSLA)
Magiredi: 42, 50, 55, 60, 65
Mphamvu: Yoposa chitsulo cha kaboni wamba.
Kupereka: Ma mbale, ma angles, ma channel, ma beams ndi zina zambiri
Magiredi otsika (Giredi 42,50) amatha kulumikizidwa pogwiritsa ntchito njira zowotcherera wamba, Magiredi apamwamba (Giredi 65) amafunika njira zapadera zowotcherera kapena kufufuza kwina monga PWHT ndi zina zotero.

ASTM A283
Mtundu: Chitsulo chopangidwa ndi kaboni (chitsulo chofatsa)
Magiredi: ABCD = Ikupezeka
Mphamvu: Yofooka kuposa A572 ndi A992
Munganene kuti zinali ngati kupanga ndi kulumikiza mwana wa njovu pamtengo wa njovu yaikulu.
Chokhacho chopepuka kapena.General ASTM A283 ndi chomwe chimagwiritsidwa ntchito ndi zinthu zosafunikira kwenikweni.

ASTM A913
Mtundu: Chitsulo cholimba kwambiri chotsika ndi njira ya QST (yozimitsa ndi kudziletsa)
Magiredi: 50, 65, 70 = Akupezeka
Mbali: Mphamvu yayikulu, kulimba kwapadera komanso kusinthasintha bwino mu chitsulo champhamvu kwambiri.
Fomu Yaikulu Yopangira Matabwa Okhuthala Ndi Olemera a Flange
A913 imagwiritsidwa ntchito kwambiri pamene zigawo zolimba komanso zowonda ndizofunikira kwambiri m'mapangidwe akuluakulu komanso ataliatali achitsulo.

Kusiyana kwa Ntchito

ASTM A992
Nyumba zamalonda ndi zachitsulo za nyumba
Mafelemu a nyumba zazitali komanso zapakati
Nyumba zamafakitale ndi zogawa
Chifukwa: Itha kudaliridwa bwino komanso kulumikizidwa mosavuta, kugwiritsidwa ntchito pa thupi la galimoto.

ASTM A572
Milatho
Mafakitale
Nsanja ndi malo opangira mphamvu
Nsanja zolemera
Chifukwa: Akatswiri opanga mapangidwe amatha kukonza bwino mphamvu ndi mtengo pogwiritsa ntchito magiredi osiyanasiyana.

ASTM A283
Nyumba zotsika mtengo
Mashedi ndi ma workshop achitsulo chopepuka
Mafamu ndi nyumba zakanthawi
Zigawo zosafunikira kwenikweni
Chifukwa: Ndi yotsika mtengo komanso yosavuta kugwiritsa ntchito, koma ndi yonyamula pang'ono.

ASTM A913
Zipilala za m'mwamba
Milatho yayitali
Mabwalo amasewera ndi maholo ochitira malonda
Mapulojekiti akuluakulu a mafakitale
Chifukwa: Ziwalo zoonda komanso zazitali zimatha kupezeka ndi mphamvu zambiri.

Msika ndi Zokonda Zachigawo

Kapangidwe ka Chitsulo ka ASTM A992: Ikupezeka ku United States ndi Canada, Middle East, Southeast Asia kuti igwiritsidwe ntchito pa zomangamanga.

Kapangidwe ka Chitsulo ka ASTM A572: Amakondedwa m'madera a ku America ndi m'madera ozungulira zomangamanga monga milatho ndi nyumba zolemera.

Kapangidwe ka Chitsulo ka ASTM A283: Amagwiritsidwa ntchito kwambiri m'maiko osatukuka pakupanga zinthu zotsika mtengo komanso zopepuka.

Kapangidwe ka Chitsulo ka ASTM A913: Amagwiritsidwa ntchito makamaka m'maiko otukuka komanso m'magawo akuluakulu a mapulojekiti monga USA, Europe, Middle East, ndi East Asia.

Kuganizira za Mtengo ndi Zachuma

A283: Mtengo wotsika komanso khalidwe lotsika

A992: Mtengo wapakati, mphamvu yabwino komanso zosavuta kupanga

A572Mtengo umadalira mtundu wa

A913: Mtengo wapamwamba kwambiri pa unit, koma mphamvu zambiri zimachepetsa kuchuluka kwa chitsulo chonse

Zitsulo zolimba kwambiri zimatha kuchepetsa ndalama zonse zomwe zimagwiritsidwa ntchito pokonza zinthu, mayendedwe, ndi kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito pokonza.

Kupanga ndi Kuwotcherera

A283: Yosavuta kudula ndi kupotoza

A992: Yopangidwa kuti igwiritsidwe ntchito ngati chitsulo chosungunula

A572: Yosunthika, koma kuwongolera kolimba kumafunika kuti magiredi apamwamba

A913Njira yatsopano yomwe imalola luso lotha kulumikiza zinthu pamlingo wapamwamba kwambiri.

Chidule ndi Kuyerekeza

Muyezo Mulingo wa Mphamvu Kagwiritsidwe Ntchito Kawirikawiri Mulingo wa Mtengo Misika Yotentha
ASTM A992 Pamwamba Nyumba, mafelemu Pakatikati USA, Middle East, Southeast Asia
ASTM A572 Pakati–Pamwamba Milatho, zomera Pakati–Pamwamba America, Madera a zomangamanga
ASTM A283 Zochepa Nyumba zowala Zochepa Africa, South Asia, Central America
ASTM A913 Pamwamba Kwambiri Ma Skyscrapers, mapulojekiti akuluakulu Pamwamba USA, Europe, Middle East, ndi East Asia

ASTM A283, A992, A572 ndi A913 ndi mitundu inayi ya magwiridwe antchito a chitsulo chomangira. A283 ndi yothandiza pachuma, A992 ndi chimango chomangira chokha, A572 imapereka mitundu yosiyanasiyana ya mphamvu pa zomangamanga ndipo A913 ndi mtengo wabwino kwambiri pa ntchito zomangira zolemera komanso zapamwamba. Ntchito zomangira zolimba kwambiri zikupangitsa kuti anthu ambiri asamavutike kupita ku zitsulo zomangira zolimba kwambiri pamsika wapadziko lonse lapansi.
