Seamless steel kav tuav txoj haujlwm tseem ceeb hauv kev lag luam niaj hnub no thiab tau siv dav hauv kev tsim kho, tshuab tsim, petrochemical thiab lwm yam.TS EN 10210Tshwj xeeb tshwj xeeb tshaj tawm cov kav dej seamless steel rau cov qauv, BS EN 10210-1 yog ib qho tshwj xeeb tshwj xeeb rau cov hlau tsis muaj hlau thiab cov hlau zoo. Cov qhab nia hauv tus qauv no suav nrog S235GRH, S275JOH, S275J2H, S355JOH thiab S355J2H.

Ua ntej, S235GRH yog ib qho yooj yim qib steel, feem ntau yog siv rau cov khoom siv nyob rau hauv tsis tshua muaj kev nyuaj siab thiab chav tsev kub ib puag ncig. Nrog lub zog tawm los ntawm 235MPa, nws muaj qhov zoo weldability thiab txias formability, thiab haum rau kev tsim kho thiab cov khoom siv kho tshuab.

Tom ntej no yog S275JOH thiab S275J2H. S275JOH muaj zoo toughness ntawm -20 ℃ thiab ib tug yield zog ntawm 275MPa, thiab feem ntau yog siv rau kev tsim vaj tse thiab choj tej yaam num nrog nruab nrab loads. S275J2H muaj kev cuam tshuam zoo dua ntawm -20 ℃, thiab haum rau cov khoom siv uas yuav tsum muaj kev nyab xeeb dua.

S355 YOGthiabS355J2Hyog cov hlau uas muaj zog heev. S355JOH muaj cov tawv tawv zoo heev nyob rau hauv chav tsev kub thiab qhov kub thiab txias (-20 ℃), nrog lub zog tawm los ntawm 355MPa, thiab tau siv dav hauv cov kev ntxhov siab thiab cov haujlwm tseem ceeb, xws li cov tsev siab siab thiab cov choj loj. S355J2H muaj kev cuam tshuam ntau dua ntawm -20 ℃, thiab haum rau cov chaw txias heev lossis cov haujlwm uas yuav tsum tau muaj kev ruaj ntseg ntxiv.

EN 10210 tus qauv tsis tsuas yog qhia meej meej txog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov kav hlau, tab sis kuj tseem muab cov kev cai tshwj xeeb rau qhov ntev, qhov zoo, tsis muaj kev puas tsuaj, thiab lwm yam. siv.

Seamless steel kav yog tsim los ntawm kub dov tshuab, uas ua rau lawv zoo heev mechanical zog thiab zoo seem raug. Cov txheej txheem kub dov tuaj yeem tshem tawm cov kev ntxhov siab hauv cov yeeb nkab steel, txhim kho cov txheej txheem ntawm cov hlau, thiab txhim kho nws cov kev ua tau zoo. Piv nrog welded steel kav, seamless steel kav muaj ntau dua compressive, dabtsi yog khoov thiab torsional zog, thiab yog haum rau cov qauv kev txhawb nqa thiab cov dej thauj mus los nyob rau hauv ntau yam complex ua hauj lwm tej yam kev mob.

Feem ntau, seamless steel kav tsim raws li EN 10210 cov qauv qhia tau zoo heev hauv kev tsim kho thiab kev lag luam. Cov kav hlau steel ntawm qib xws li S235GRH, S275JOH, S275J2H, S355JOH, thiab S355J2H muaj lawv tus kheej yam ntxwv thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov haujlwm sib txawv. Lawv daim ntawv thov dav tsis tsuas yog txhim kho qhov zoo thiab kev nyab xeeb ntawm tej yaam num, tab sis kuj txhawb txoj kev loj hlob thiab innovation ntawm steel khoom technology. Xaiv cov kav dej seamless steel ntawm cov qib tsim nyog thiab cov lus qhia tshwj xeeb yog qhov tseem ceeb los ua kom muaj kev ruaj ntseg mus ntev thiab cov txiaj ntsig kev lag luam ntawm cov haujlwm.
