S355J2H Qauv ERW Steel Tube
Taw qhia rau S355J2H Cov Txheej Txheem Ua Haujlwm Welded Steel Pipe
EN 10210 S355J2H yog kub- dov hollow qauv seem tsim raws li European tus qauv EN 10210. Nws muaj qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa (phab ntsa thickness tsis tshaj 16 hli) thiab zoo heev toughness ntawm qhov kub thiab txias, muaj peev xwm tiv taus qhov cuam tshuam rau -20 degree. Qhov no ua rau nws zoo tagnrho rau ntau yam kev siv hauv kev tsim kho thiab engineering industries.
Kev tsim cov txheej txheem ntawm EN 10210 S355J2H Hlau Yeeb Nkab: EN 10210 S355J2H steel yeeb nkab tuaj yeem tsim siv cov txheej txheem seamless lossis welded. Ob txoj kev welding feem ntau suav nrog:
Resistance Welding (ERW): Cov txheej txheem no siv cov cua sov thiab siab rau vuam cov ntaub ntawv ua ke. Nws yog qhov ua tau zoo, tsim nyog rau kev tsim khoom loj, thiab siv tau rau cov kav hlau steel ntawm ntau cov phab ntsa thicknesses thiab cov ntaub ntawv.
Submerged arc welding (SAW): Submerged arc welding tsim ib qho arc nyob rau hauv ib txheej ntawm granular flux, ua rau kom tob tob thiab zoo dua weld zoo. Nws yog tshwj xeeb tshaj yog haum rau welding thicker profiles.
