EN 10210 S355J2Hyog kub-tiav cov qauv hollow seem steel raws liTS EN 10210nrog rau qhov tsawg kawg nkaus yield zog ntawm 355 MPa (rau phab ntsa thicknesses ≤ 16 mm) thiab zoo cuam tshuam cov khoom nyob rau hauv qis kub mus rau -20 ° C, ua rau nws zoo tagnrho rau siv nyob rau hauv ntau yam ntawm lub tsev thiab engineering lug.
Yog, EN 10210 =BS EN 10210.
BS EN 10210 thiab EN 10210 yog tib yam hauv cov ntsiab lus kev ua haujlwm thiab ob qho tib si sawv cev rau cov qauv European rau kev tsim, tsim khoom, thiab cov cai rau cov txheej txheem thermoformed hollow seem.
BS EN 10210 yog cov qauv siv hauv UK, thaum EN 10210 yog tus qauv thoob plaws European.Lub cev sib txawv ntawm lub teb chaws tus qauv yuav ua ntej tus qauv nrog cov ntawv luv luv hauv lub tebchaws, tab sis cov ntsiab lus tseem ceeb ntawm tus qauv tseem zoo ib yam.
Hollow seem yuav categorized li ncig, square los yog rectangular, los yog elliptical.
Tsis tas li vim nws yog cov txheej txheem kub ua tiav raws li EN 10210, cov ntawv luv luv hauv qab no tuaj yeem siv tau.
HFCHS= kub tiav ncig hollow seem;
HFRHS= kub tiav square lossis rectangular hollow seem;
HFEHS= kub tiav elliptical hollow seem.
Round: Sab nraud txoj kab uas hla mus txog 2500 mm;
Phab ntsa thicknesses txog 120 mm.
Tau kawg, tsis muaj txoj hauv kev los tsim cov raj ntawm qhov loj thiab phab ntsa tuab yog tias siv cov txheej txheem ERW vuam.
ERW tuaj yeem tsim cov raj mus txog 660mm nrog phab ntsa tuab ntawm 20mm.
Hlau tuaj yeem tsim los ntawm ib qhoseamless los yog vuamtxheej txheem.
Ntawm covcov txheej txheem vuam, feem ntau welding txoj kev suav nrogERW(electrical resistance welding) thiabSAW(submerged arc vuam).
Ntawm lwm tus,ERWyog cov txheej txheem vuam uas koom nrog cov khoom hlau ua ke los ntawm kev tiv thaiv tshav kub thiab siab.Cov txheej txheem no siv tau rau ntau yam khoom siv thiab cov thicknesses thiab ua rau cov txheej txheem vuam zoo.
SAW, ntawm qhov tod tes, yog ib txoj kev vuam uas siv cov dej ntws los npog cov arc, uas muab kev nkag mus tob dua thiab zoo dua weld zoo thiab tshwj xeeb tshaj yog haum rau vuam tuab daim hlau.
Tom ntej no, yog cov txheej txheem ERW, uas yog cov txheej txheem tsim tau zoo heev uas tau siv los ua ntau yam ntawm cov raj steel thiab cov profiles.
Nws yuav tsum tau muab sau tseg tias rau unalloyed thiab nplua-grain hollow seem fabricated los ntawm cov txheej txheem vuam, kho welds tsis raug tso cai tsuas yog rau submerged arc vuam.
Zoo JR, JO, J2 thiab K2 - kub tiav,
Qhov tsawg kawg nkaus tawm lub zog ntawm S355J2H steel yeeb nkab tsis ruaj, nws yuav hloov nrog cov phab ntsa sib txawv.
Tshwj xeeb, lub zog tawm los ntawm S355J2H tau teeb tsa raws li tus qauv thaum cov phab ntsa tuab tsawg dua lossis sib npaug li 16 hli, tab sis thaum phab ntsa thickness nce, lub zog tawm los yuav raug txo, yog li tsis yog tag nrho S355J2H steel yeeb nkab tuaj yeem ncav cuag qhov tsawg kawg nkaus yield. Lub zog ntawm 355MPa.

S355J2H steel yeeb nkab yog lub zog muaj zog steel yeeb nkab nrog kev ua haujlwm zoo vuam thiab tsis tshua muaj kev kub ntxhov, yog li nws muaj ntau yam kev siv hauv ntau qhov chaw lag luam.
1. Kev tsim kho: siv nyob rau hauv txuas hniav, yees, thav duab, rail tsheb thauj mus los, subways, ru thav duab, phab ntsa panels, thiab lwm yam vaj tse.
2. Piping system: Siv los ua cov kav dej rau kev thauj cov kua dej, tshwj xeeb tshaj yog nyob rau lub sijhawm uas yuav tsum muaj lub zog siab thiab siab ua haujlwm.
