Nkhani - ASTM H Beam Specifications, Zipangizo ndi Mapulogalamu | Wogulitsa Beam ya Structural Steel Wide Flange Beam

Ngakhale kuti ndalama zogulira zomangamanga padziko lonse lapansi zikukwera kwambiri ku North America, Latin America, ndi Southeast Asia,ASTM H Beamikadali pakati pa zigawo zodziwika bwino zachitsulo zomwe zimagwiritsidwa ntchito popanga zinthu zamalonda, mafakitale, ndi zomangamanga. Imanyamula katundu wambiri, imakhala yolimba bwino komanso imakwaniritsa muyezo waku America. Imagwiritsidwa ntchito kwambiri m'makina omanga omwe amapereka magwiridwe antchito apamwamba padziko lonse lapansi.

ASTM-A572-Gr50-A992-Wide-Flange-Ipe-270-Ipe-300-Heb-260-Hea-200-Construction-Universal-Beam (1)

Mafotokozedwe Ofunika a ASTM

Matabwa a ASTM H (omwe amadziwikanso kuti matayala akuluakulu a flange) nthawi zambiri amapangidwa motsatira miyezo iyi:

ASTM A36 Mzere wa H- Chitsulo cha kaboni chopangidwa ndi nyumba ndi mapulojekiti opepuka a mafakitale
ASTM A572 Mzere wa H- Chitsulo cha HSLA chokhala ndi chiŵerengero chabwino cha mphamvu ndi kulemera
ASTM A992 Mzere wa H- Mtundu wosankhidwa kwambiri wa matabwa a flange ozungulira omwe ali pamsika wa US
ASTM A588 Mzere wa H- Chitsulo chosagwira dzimbiri cha milatho ndi nyumba zakunja

Pakati pa izi, mtundu wofala kwambiri ku US ndiMzere wa flange wokulirapo wa ASTM A992, yomwe ili ndi mphamvu yolinganizika, kuthekera kowongoleredwa komanso kuthekera kodulira bwino.

Katundu wa Zinthu ndi Magwiridwe Abwino a Makina

Mapulogalamu Aakulu

Makhalidwe a makina wamba (amasiyana malinga ndi kalasi):

Mphamvu Yopereka: 250–345 MPa (36–50 ksi ndi kupitirira apo)
Kulimba kwamakokedwe: 400–550 MPa
Kutha kusweka bwino komanso kupangika bwino
Kukana mwamphamvu kupindika ndi kupsinjika

Gawo looneka ngati H limapereka:

1. High gawo modulus

2. Kugawa katundu moyenera

3. Kugwiritsidwa ntchito kwachitsulo kochepa poyerekeza ndi mipiringidzo yachikhalidwe ya I

4. Kuchita bwino kwambiri pazochitika za zivomerezi ndi mphepo

Mapeto a ASTM H Beam

ASTM H Beam kapena Wide Flange Beam ndi chinthu chotsogola pakupanga zitsulo masiku ano. Kaya ntchitoyi ndi yosungiramo zinthu zamafakitale, yomanga zitsulo zamalonda, kapena yomanga milatho, ASTM structural H dams imapereka mphamvu, kudalirika komanso kutsatira malamulo padziko lonse lapansi.

Kwa ogulitsa zitsulo ndi makontrakitala omanga, ndikofunikira kuti asankhe wogulitsa wodalirika wa H beam yemwe angakwaniritse zofunikira zapamwamba komanso wotsimikiziridwa ndi miyezo yapadziko lonse lapansi kuti akhalebe opikisana nawo chaka cha 2026 ndi kupitirira apo.
