S355J2H Resistance Welded Steel Pipe Khoom Taw qhia
S355J2H ERW (kuj welded) steel yeeb nkab yog ib qho txias -tsim cov yeeb nkab tsim los ntawm kev siv lub cev muaj zog- lub zog steel qauv S355J2H ua cov khoom siv hauv paus thiab ua haujlwm siab -frequency resistance welding technology. Cov khoom no ua ke cov khoom zoo heev ntawm S355J2H steel nrog lub siab -kev ua tau zoo ntawm cov txheej txheem ERW, uas muaj qhov tseeb qhov tseeb, ruaj khov weld zoo, thiab cov nqi tsim khoom tsawg. Nws yog dav siv hauv kev tsim vaj tsev, kev tsim tshuab, thiab kev thauj mus los hauv cov kav dej.

Kev soj ntsuam zoo ntawm ERW Welded Yeeb Nkab S355J2H
Kev tshuaj xyuas zoo ntawm S355J2H ERW kuj welded steel yeeb nkab nruj me ntsis raws li EN 10219 tus qauv. Eddy kev sim tam sim no thiab kev kuaj ultrasonic yog siv los ua 100% tsis yog -kev tshuaj ntsuam xyuas ntawm cov vuam seam kom ntseeg tau tias tsis muaj qhov tsis xws luag xws li tsis muaj fusion, porosity, thiab inclusions. Nyob rau tib lub sijhawm, kev tshuaj xyuas microstructure tom qab cov txheej txheem hauv online normalizing txheeb xyuas cov nplej loj (Ntau dua lossis sib npaug rau 7 qib) thiab hardness uniformity (tsawg dua lossis sib npaug rau 180HV) ntawm thaj chaw weld. Nws tseem tau nruab nrog -20℃Charpy impact test (Ntau dua lossis sib npaug rau 27J) thiab qhov ntsuas qhov ntsuas qhov ntsuas tag nrho. Thaum kawg, ib qho kev sim hydrostatic yog siv los txheeb xyuas cov yeeb nkab lub cev nruj, ua kom tiav cov txheej txheem traceability.
