Txheej txheem ntau lawm
1. Cov yeeb nkab steel feem ntau yog ua los ntawm cov hlau phaj welded rau hauv cov duab cylindrical. Raws li cov txheej txheem tsim, steel yeeb nkab pawg tuaj yeem muab faib ua ob pawg:
(1) Welded yeeb nkab pawg: Hom yeeb nkab pawg no yog tsim rau hauv cov duab cylindrical los ntawm vuam steel phaj ua ke. Welds muab lub zog thiab kev ua haujlwm ruaj khov.
(2) Seamless steel yeeb nkab pawg: Cov yeeb nkab no yog ua los ntawm seamless steel yeeb nkab yam tsis muaj cov ntsiab lus vuam. Lawv muaj kev ncaj ncees zoo heev thiab feem ntau yog thawj qhov kev xaiv rau tej yaam num uas yuav tsum tau ntau dua load-bearing muaj peev xwm.
2. Cov ntawv hlau yog tsim los ntawm dov steel phaj rau hauv U lossis Z duab. U-shaped steel ntawv pawg muaj ib qho kev sib cuam tshuam, thaum Z-shaped steel ntawv pawg muaj ob qhov sib cuam tshuam, muab kev ruaj ntseg ntau dua thiab tsim tau yooj yim.
