Ntsiab Specifications & Cov ntsiab lus
Kev Tswj Xyuas Cov Qauv: Daim ntawv no tau hais los ntawm tus qauv ASTM tshwj xeeb:
Cov duab puab: ASTM A992 (uas hloov pauv A572 Gr. 50 rau feem ntau W- cov duab) yog tam sim notseem ceebtxheem rau dav -flange beams. A572 Gr. 50 tseem raug hu tawm rau lwm cov duab.
Phaj, Bars, thiab Sheets: ASTM A572 / A572M yog tus qauv ncaj qha.
HSS: ASTM A1085 (rau HSS) lossis A500 (txawm tias A500 Qib C yog ntau dua rau tubing).
Kev sib koom ua ke: Dav - flange kab teeb (A992, uas yog tshuaj lom neeg thiab tshuab zoo ib yam li A572 Gr. 50) thiab daim hlau yog cov khoom siv dav tshaj plaws thiab siv cov ntawv.
Muaj: Nws yog ib lub zeb- cov khoom tsim tau yooj yim los ntawm cov neeg tsim khoom hlau loj, cov chaw pabcuam, thiab cov xa khoom hauv North America thiab thoob ntiaj teb.
Cov Lus Qhia Txog Kev Muag Khoom: Thaum qhia meej, ib txwm hais cov khoom siv qib (A572 Qib 50) thiab cov qauv tsim khoom (piv txwv li, ASTM A572 Phaj, lossis ASTM A992 rau W-beams) kom ntseeg tau tias koj tau txais cov khoom raug.
