Cov ntsiab lus N-binding yuav tsum tau sau tseg rau hauv Daim Ntawv Tshuaj Xyuas.
Cov ntaub ntawv xaiv hauv BS EN 10210 yog raws li lawv qhov tsawg kawg nkaus lub zog ntawm 16 hli phab ntsa tuab thiab cov khoom cuam tshuam ntawm qhov kub tshwj xeeb. Lub zog tso zis, lub zog tensile, thiab elongation ntawm BS EN 10210 S355J0H txo qis raws li phab ntsa tuab nce.
BS EN 10210 tso cai rau kev tsim khoom siv ntau yam txheej txheem tsim khoom, feem ntau suav nrog cov txheej txheem vuam seamless, LSAW, SSAW, thiab ERW.
Hauv qab no yog ntau qhov ntau thiab tsawg rau cov txheej txheem tsim khoom.
Los ntawm qhov kev sib piv saum toj no, nws tuaj yeem pom tias cov yeeb nkab hlau tsis muaj qhov zoo dua hauv kev tsim cov yeeb nkab hlau tuab, tshwj xeeb tshaj yog cov yeeb nkab hlau me me, tab sis nws qhov loj me yuav raug txwv. Yog tias koj xav tau tsim cov yeeb nkab hlau nrog txoj kab uas hla ntau dua 660 hli, nws yuav nyuaj dua.
Cov Yeeb Nkab Dub
Qhov no hais txog cov yeeb nkab hlau uas tsis muaj kev kho saum npoo.
Kev Tiv Thaiv Ib Ntus
Txhawm rau tiv thaiv kev xeb ntawm cov kav hlau thaum lub sijhawm khaws cia, kev thauj mus los, lossis kev teeb tsa, ib txoj hauv kev uas feem ntau yog txheej xim lossis cov kua roj vanish rau saum npoo ntawm cov kav dej.
Txheej Txheem Tiv Thaiv Kev Xeb
Muaj ntau hom tshuaj tiv thaiv xeb, suav nrog xim pleev, FBE,3LPE, thiab galvanized. Txhua hom txheej muaj cov yam ntxwv tshwj xeeb thiab cov chaw ib puag ncig siv tau. Kev xeb thiab xeb tuaj yeem tiv thaiv tau zoo los ntawm kev siv cov txheej tiv thaiv xeb tsim nyog rau cov hlau.
EN 10210 Cov txheej txheem galvanized kub dip rau ntawm cov yeeb nkab hlau yuav tsum ua raws li cov kev cai ntawm EN ISO 1461.
