Khoom Taw qhia ntawm S355j2h Loj Diameter Submerged Arc Welded Yeeb Nkab
Loj txoj kab uas hla LSAW carbon steel yeeb nkab yog tsim los ntawm ib txheej ntawm nruab nrab -thickness steel phaj. Cov hlau phaj yog nias thiab dov rau hauv cov yeeb nkab dawb paug hauv pwm lossis lub tshuab ua haujlwm, tom qab ntawd raug rau ob -sab submerged arc vuam thiab txoj kab uas hla nthuav dav. Cov khoom tiav lawm muaj ntau yam specifications, zoo toughness, zoo heev plasticity, thiab uniform thiab ntom weld seams. Nws nta loj txoj kab uas hla, tuab phab ntsa, siab tsis kam, tsis kub tsis kam, thiab muaj zog corrosion kuj.

Kev soj ntsuam zoo ntawm S355J2H Loj - Txoj kab uas hla ncaj Seam Submerged Arc Welded Yeeb Nkab
Kev tshuaj xyuas zoo ntawm S355J2H loj- txoj kab uas hla LSAW welded dub carbon steel yeeb nkab nruj me ntsis raws li EN 10210 tus qauv. Ultrasonic thiab X-ray kuaj yog siv rau 100% tsis yog- kuaj kev puas tsuaj ntawm qhov ntev weld seam. Nyob rau tib lub sijhawm, kev ntsuas siab hydrostatic txheeb xyuas cov yeeb nkab siab -cov kabmob muaj peev xwm (kuaj siab tshaj lossis sib npaug li 1.5 npaug ntawm kev ua haujlwm siab thiab tuav rau 10 vib nas this). Cov qauv los ntawm cov khoom siv hauv paus thiab qhov chaw weld undergo tensile, dabtsi yog khoov, thiab -20℃Charpy impact tests kom ntseeg tau tias lub zog tawm los ntau dua lossis sib npaug rau 355MPa thiab cuam tshuam lub zog ntau dua lossis sib npaug rau 27J. Lub laser scanner yog siv los tshuaj xyuas cov yeeb nkab roundness (kev kam rau siab Tsawg dua lossis sib npaug rau ± 0.3%). Thaum kawg, ib qho kev soj ntsuam tas mus li yog txau rau ntawm cov yeeb nkab phab ntsa, tsim kom muaj cov ntaub ntawv zoo.
