EN 10210 tus qauv yog European specification uas qhia txog cov txheej txheem kev xa khoom rau kub- tiav cov qauv hollow seem ua los ntawm cov tsis yog - alloy thiab nplua nplej hlau. Cov seem hollow no feem ntau yog siv nyob rau hauv kev tsim kho, civil engineering, machinery, thiab steel qauv, thiab yog yus muaj los ntawm lawv lub zog siab, weldability zoo heev, thiab lub zog zoo - rau - nyhav piv.
EN 10210 muaj ob qhov tseem ceeb
TS EN 10210-1
Cov xwm txheej kev xa khoom
TS EN 10210-2
Tolerances, qhov ntev, thiab cov khoom seem
Cov txheej txheem no qhia txog qhov yuav tsum tau ua rau kub- ua tiav cov txheej txheem hollow seem uas tau tsim los ntawm qhov kub siab, feem ntau yog los ntawm cov txheej txheem xws li kub sib sau los yog extrusion, thiab tej zaum yuav muab nyob rau hauv raws li - kub- tsim mob los yog tom qab cua sov- kho.
Yog tias koj ua haujlwm nrog cov voj voog, square, lossis lub voj voos hollow seem (CHS, SHS, RHS), tshwj xeeb tshaj yog nyob rau hauv cov qauv siv, kev nkag siab txog EN 10210 tus qauv yog qhov tseem ceeb los xyuas kom meej cov khoom zoo, kev tswj hwm, thiab kev ua haujlwm zoo.

EN 10210-1 Scope ntawm daim ntawv thov
TS EN 10210-1 qhia txog cov kev cai tshwj xeeb rau cov kub- tiav cov voj voog, square, thiab cov duab plaub lub hollow seem. Nws muaj feem xyuam rau cov ntu uas ua los ntawm kub- txheej txheem tsim nrog lossis tsis muaj kev kho cua sov tom qab. Nws tshwj xeeb yog npog cov hlau tsis-alloy thiab nplua grain steels.
Hauv cov ntsiab lus, EN 10210-1 thiab EN 10219-1 yog ob qho tib si cov qauv kev sib haum xeeb raws li Kev Tswj Xyuas Khoom Siv Khoom Siv (CPR). Cov kav hlau sib txuas feem ntau yog tsim los rau kev tsim kho. Qhov sib txawv tseem ceeb yog EN 10210-1 siv rau cov ntu kub-tiav hollow, thaum EN 10219-1 siv rau cov ntu txias-tsim welded hollow seem.
EN 10210 cov lus qhia tshwj xeeb qhia txog cov txheej txheem kev xa khoom rau kub - tiav cov qauv hollow seem. Nws yog ib qho tseem ceeb heev rau kev siv cov txheej txheem xws li kev tsim vaj tsev, txuas hniav, thiab lwm yam kev tsim vaj tsev, muab kev lees paub tseem ceeb rau cov khoom xws li lub zog tawm los, lub zog tensile, thiab kev cuam tshuam.
Classified Steels
Cov hlau tau muab faib ua EN 10210 rau hauv ob pawg loj, zoo ib yam li EN 10219:
• 1. Tsis yog- alloy steels
• 2. Fine grain steels
Rau cov uas tsis yog - alloy steel structural hollow seem, lub npe yuav tsum muaj xws li:
• Tus naj npawb ntawm European Standard (EN 10210);
• Tsab ntawv loj S rau cov qauv hlau;
• Qhov taw qhia ntawm qhov tsawg kawg nkaus lub zog tawm los rau thickness Tsawg dua los yog sib npaug rau 16 hli, qhia hauv N / mm²;
• Tsab ntawv loj J thiab tus lej (0 lossis 2) rau cov khoom zoo nrog cov khoom muaj feem cuam tshuam ntawm 0℃thiab -20 degree, feem;
• Tsab ntawv loj H los qhia cov seem hollow.
Piv txwv li: EN 10210 S275J0H
• EN 10210 - Tus lej ntawm European Standard
• S - Cov qauv hlau
• 275 – Yam tsawg kawg nkaus yield zog (N/mm²) rau thickness tsis ntau tshaj 16 hli
• J0 – Impact zog, 27 J yam tsawg kawg nkaus ntawm 0 degree
• H – Hollow seem
Rau nplua grain steel structural hollow seem, steel designation muaj xws li:
• Tus naj npawb ntawm European Standard (EN 10210);
• Tsab ntawv loj S rau cov qauv hlau;
• Qhov taw qhia ntawm qhov tsawg kawg nkaus lub zog tawm los rau thickness Tsawg dua los yog sib npaug rau 16 hli, qhia hauv N / mm²;
• Tsab ntawv loj N los qhia txog cov khoom siv uas ua tau zoo lossis cov khoom siv zoo li qub, lossis tsab ntawv loj M los qhia cov khoom siv thermomechanically dov;
• Tsab ntawv loj L rau cov khoom zoo nrog cov khoom muaj feem cuam tshuam ntawm -50℃;
• Tsab ntawv loj H los qhia cov seem hollow.
Piv txwv li: EN 10210 S355NH
• EN 10210 - Tus lej ntawm European Standard
• S - Cov qauv hlau
• 355 - Yam tsawg kawg nkaus yield zog (N / mm²) rau thickness tsis ntau tshaj 16 hli
• N – Normalized los yog normalized dov zoo nplej hlau
• H – Hollow seem
*(Ceeb Toom: Rau cov khoom zoo nrog cov khoom cuam tshuam ntawm -50 degree, 'NL' yuav raug siv, piv txwv li, S355NLH).*
