S355J2H LSAW welded yeeb nkab yog dab tsi?
S355J2H LSAW welded yeeb nkabyog cov qauv steel yeeb nkab ua los ntawmS355J2H hlau, uas muaj npe nrov rau nws lub zog siab thiab qis -kub toughness. "LSAW" qhia tias nws yog tsim los siv ib tug longitudinal submerged arc vuam txheej txheem, uas ua rau ib tug muaj zog thiab zoo li qub weld thiab feem ntau yog siv nyob rau hauv lub tsim ntawm loj - txoj kab uas hla kav.
Lub zog ntawm S355J2H yog dab tsi?
S355J2Hyog kub- dov structural hollow profile dav siv hauv kev tsim kho thiab engineering. Nws yog ua los ntawm cov hlau tsis muaj - alloy zoo- cov hlau uas muaj qhov muaj zog tsawg kawg nkaus ntawm 355 N / mm².
S355J2H LSAW welded yeeb nkab yog dab tsi?
Lub ntsiab vuam txoj kev rauS355J2H LSAW (longitudinal submerged arc welded) steel yeeb nkabyog ob -sab submerged arc vuam (DSAW), uas siv cov txheej txheem flux los tiv thaiv cov arc thiab vuam.
Qhov zoo ntawm S355J2H LSAW steel yeeb nkab yog dab tsi?
Qhov zoo ntawmS355J2H LSAW steel yeeb nkabsuav nrog nws lub zog siab thiab siab tawv, ua kom nws tiv taus cov khoom hnyav thiab cuam tshuam; thiab nws qhov ua tau zoo heev qis - qhov kub thiab txias, tswj kev ruaj ntseg txawm nyob hauv qhov chaw txias. Tsis tas li ntawd, nws muaj qhov zoo tshaj plaws weldability.
Cov haujlwm engineering twg tsim nyog siv S355J2H LSAW steel yeeb nkab?
S355J2H LSAW welded steel yeeb nkabyog tsim rau kev tsim engineering (bridges, tsev, yees), marine engineering (platforms, pawg hauv paus), thiab lub zog infrastructure (cua turbine yees, pipeline txhawb).
