Hauv kev tsim kho, kev tsim khoom siv tshuab, thiab kev tsim kho vaj tse thoob plaws Tebchaws Europe, kev xaiv cov hlau ua vaj tse yuav tsum ua raws li EU cov qauv.S355J2Hqib hlau, txhais raws liEN10219Rau cov khoom siv welded txias, nws sawv tawm vim nws qhov kub qis zoo heev, weldability ruaj khov, thiab lub zog siab. Yog li ntawd, nws tau dhau los ua cov khoom siv tshwj xeeb rau ntau qhov project European. Tsab xov xwm no muab kev txheeb xyuas txog S355J2H txog kev ua raws li tus qauv, cov khoom siv, cov ntawv thov ib txwm muaj, thiab kev txiav txim siab txog kev muab khoom rau kev lag luam European.

1. Kev Piav Qhia Txog Tus Qauv thiab Qib

EN10219: Tus qauv no qhia txog cov xwm txheej kev xa khoom rau cov khoom siv vuam txias, cov khoom plaub fab, lossis cov khoom plaub fab uas ua los ntawm cov hlau tsis yog hlau thiab cov hlau zoo. Nws suav nrog cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, kev kam rau siab, thiab cov kev cai sim tsis ua puas tsuaj.

S355J2H:

S: Cov Hlau Ua Vaj Tse

355: Yam tsawg kawg nkaus yield zog ntawm 355 MPa (rau phab ntsa thickness≤16 hli)

J2: Charpy V-notch impact energy≥27J ntawm -20°C

H: Tshooj Hollow

2. Cov Khoom Siv Tseem Ceeb thiab Cov Txheej Txheem

Tus Nqi Ib Txwm Muaj / Qhov Yuav Tsum Tau Ua rau Cov Haujlwm European

Lub Zog Tawm (ReH)≥355 N/hli²Txo qhov hnyav ntawm tus kheej thiab tag nrho cov hlau siv

Lub zog tensile (Rm) 470–630 N/hli²Muab kev nyab xeeb txhim khu kev qha

Kev ncab tom qab tawg≥20% Xyuas kom meej tias ua tau rau kev khoov txias thiab tsim

Kev cuam tshuam qis ntawm qhov kub thiab txias (-20)°C)≥27J Haum rau thaj chaw txias xws li Central thiab Northern Europe

Kev vuam tau CEV≤0.40 (ib txwm) Sib xws nrog cov txheej txheem vuam feem ntau, tsawg kawg preheating

3. Cov Ntawv Thov Ib Txwm Muaj (Cov Piv Txwv Txog Kev Lag Luam Hauv Tebchaws Europe)

Tsev & Kev Tsim Kho Vaj Tse: Cov trusses ntawm chaw ua si, cov canopies ntawm chaw nres tsheb, cov txhawb nqa pej thuam, cov qauv shoring ib ntus.

Cov Tshuab thiab Khoom Siv: Crane booms, cov khoom siv conveyor, cov khoom siv ua liaj ua teb.

Cov Choj & Cov Chaw Pabcuam Kev: Cov choj rau cov neeg taug kev, cov txheej txheem thaiv kev, cov qauv tiv thaiv kev sib tsoo.

Kev Tsim Kho Zog & Ib puag ncig: Kev txhawb nqa sab hauv rau cov pej thuam cua, cov thav duab PV mounting, cov qauv platform rau kev kho dej khib nyiab.

4. Cov Kev Xav Tseem Ceeb rau Kev Nkag Mus Rau Hauv Kev Lag Luam European

Daim Ntawv Pov Thawj EN 10204: Daim ntawv pov thawj tshuaj xyuas hom 3.1 lossis 3.2 feem ntau yog xav tau los ua pov thawj tias ua raws li tus qauv.

Kev Tswj Xyuas Qhov Nto & Qhov Loj: Ua raws li qhov yuav tsum tau ua kom haum raws li EN10219-2; qhov chaw yuav tsum tsis muaj kab nrib pleb, laps, lossis lwm yam tsis zoo.

Kev taug qab: Txhua qhov seem hollow yuav tsum tau cim nrog qib hlau, tus lej cua sov, thiab tus lej txheem kom ntseeg tau tias taug qab tag nrho.

DoP (Declaration of Performance): Yog tias cov khoom muaj lub cim CE, yuav tsum muaj Daim Ntawv Tshaj Tawm Txog Kev Ua Tau Zoo raws li Txoj Cai Tswjfwm Khoom Siv (CPR).

EN10219 S355J2H, nrog nws lub zog sib npaug, qhov kub qis zoo heev, thiab kev ua haujlwm zoo, sib haum xeeb zoo nrog kev lag luam European's xav tau cov hlau ua vaj tse uas muaj kev nyab xeeb, txhim khu kev qha, thiab ua haujlwm tau zoo. Rau cov neeg muab khoom uas xav nkag mus lossis nthuav dav hauv Tebchaws Europe, kev muab cov ntaub ntawv zoo tiav, kev tswj hwm kev kam rau siab, thiab kev xyuas kom meej tias cov khoom siv taug qab tau yog qhov tseem ceeb rau kev siv cov khoom no hauv cov haujlwm European.
