EN 10210 yog European txheem rau kub -} ua tiav cov kab lus hollow (hssS355J2Hyog cov qib tshwj xeeb hauv cov txheej txheem no, siv ntau yam tsawg kawg nkaus ntawm cov khoom siv thuv
- Khoom Siv Khoom: S355J2H
- S355: Yam tsawg kawg los kom muaj zog ntawm355 MPa(Tsawg dua li lossis sib luag rau 16 hli tuab).
- J2: Qhia txog tej yam kev cuam tshuam nyuaj ntawm-20 degree(Charpy v - notch ntsuas).
- H: Txhais tauHollow cov ntu(kub -} tiav).
Cov txheej txheem tsim khoom
- ERW (hluav taws xob tiv taus vuam):
Cov txheej txheem no siv tiv thaiv tshav kub thiab siab rau cov ntaub ntawv nyiaj. Nws yog qhov ua tau zoo, haum rau huab hwm coj ntau lawm, thiab ua haujlwm zoo thoob plaws ntau yam tuab thiab cov khoom siv. - Pom (submerged arc vuam):
Tus txheej txheem no cuam tshuam hauv cov txheej txheem hauv qab txheej ntawm glux glux, ua rau tob nkag thiab superior weld zoo. Nws yog qhov tshwj xeeb rau cov ntawv tuab.

Cov Ntawv Thov
Vim tias nws lub zog siab, Weldability zoo, thiab muaj qis qis {{}}} kub ua tau zoo, en 10210 tau siv dav hauv ntau cov haujlwm, suav nrog:
- Kev tsim kho thiab vaj tse ib puag ncig: Qhov zoo tagnrho rau kev siv hauv cov choj, vaj tse, yees, trusses, subway systems, thiab ru tsev lossis phab ntsa qauv.
- Cov Tshuab Luam Nruab: Haum rau kev ntxig kua hauv kev ntxhov siab, tshwj xeeb tshaj yog cov tshuab yuav tsum muaj ob qho muaj zog thiab lub zog.
- Tubrog Nkoj thiab Offshore Engineering:Siv nyob rau hauv lub nkoj shrbuilding, othore platforms, thiab marine txheej txheem sib xyaw.
- Zog Kev Lag Luam: Feem ntau siv rau hauv cua fais kev sib sau, roj rigs, thiab kev kis cov pipelines.
- Siab Hlab:Siv rau hauv kev tsim khoom ntawm kev kub siab - Cov khoom siv cov kabmob sov thiab vuam cov qauv.
- Tsuas thiab chaw txua txiag zeb:Ua haujlwm hauv cov txheej txheem txheej txheem rau cov mines, suav nrog cov thav duab convitor thiab ore kev siv tshuab.
Qhov Zoo
