S355J2H Kauv Welded Steel Pipe yog dab tsi?
S355J2H kauv welded steel yeeb nkabyog ib hom kauv welded steel yeeb nkab ua los ntawm ib qib tshwj xeeb ntawm cov qauv hlau. Nws yog tsim los siv cov txheej txheem welding, thiab nws cov khoom siv (txhais los ntawm S355J2H lub npe) suav nrog qhov tsawg kawg nkaus lub zog ntawm 355 MPa thiab zoo toughness txawm nyob rau ntawm qhov kub thiab txias li -20 degree.
Dab tsi yog cov ntaub ntawv raw rau S355J2H SSAW welded yeeb nkab?
Lub ntsiab raw khoom rauSSAW welded yeeb nkabyog steel coil. Cov coils no feem ntau yog ua los ntawm qis- carbon steel lossis qis- alloy steel, nrog rau cov qib steel tshwj xeeb nyob ntawm qhov xav tau siv thiab cov kev xav tau ntawm cov yeeb nkab tiav.
S355J2H SSAW welded yeeb nkab yog dab tsi?
Kauv steel yeeb nkab (SSAW steel yeeb nkab)yog ib qho kauv seam steel yeeb nkab ua los ntawm sawb steel coils, feem ntau yog siv cov txheej txheem extrusion, thiab tom qab ntawd welded los ntawm tsis siv neeg ob -hlau ob -sided submerged arc vuam. Kauv welded steel kav yog tsim los ntawm kev pub sawb hlau rau hauv lub vuam yeeb nkab chav tsev, qhov uas nws maj mam dov mus rau hauv ib puag ncig lub raj tsis muaj qhov qhib tom qab ntau - yob dov. Qhov sib txawv weld yog tswj rau 1-3mm los ntawm kev kho lub siab ntawm lub siab rollers, kom ntseeg tau tias cov weld xaus yog flush.
Dab tsi engineering tej yaam num yog S355J2H kauv welded steel kav tsuas yog siv rau?
S355J2H kauv welded steel kavFeem ntau yog siv rau hauv kev siv cov qauv, xws li cov hauv paus hauv paus, kev tsim kho choj, thiab cov qauv hauv hiav txwv, nrog rau cov dej qis qis hauv cov dej thiab cov kav dej.
Dab tsi yog qhov zoo ntawm S355J2H kauv welded steel kav piv rau ncaj seam welded steel kav?
S355J2H kauv submerged arc welded (SSAW) kavmuaj qhov zoo tshaj qhov ncaj seam welded kav vim tias lawv tuaj yeem tiv taus siab dua, tsim cov kab loj dua, thiab muaj kev sib tsoo zoo dua. Tsis tas li ntawd,S355J2H hlaukuj muaj lub zog siab thiab qis -kev ua haujlwm kub. Thaum ob qho tib si muaj zog, SSAW vuam txheej txheem muaj qhov tshwj xeeb zoo hauv kev tsim khoom thiab kev ua haujlwm.
