EN 10210 S355J2Hyog ib qho hlau hollow section uas kub-ua tiav raws liEN 10210nrog rau qhov tsawg kawg nkaus ntawm 355 MPa (rau phab ntsa tuab ≤ 16 hli) thiab cov khoom cuam tshuam zoo ntawm qhov kub qis mus rau -20 ° C, ua rau nws zoo tagnrho rau kev siv hauv ntau yam kev tsim kho thiab kev tsim kho vaj tse.
Yog, EN 10210 =BS EN 10210.
BS EN 10210 thiab EN 10210 zoo ib yam hauv cov ntsiab lus kev siv tshuab thiab ob qho tib si sawv cev rau cov qauv European rau kev tsim qauv, kev tsim khoom, thiab cov kev cai rau cov ntu thermoformed structural hollow.
BS EN 10210 yog qhov version uas tau txais yuav hauv UK, thaum EN 10210 yog tus qauv thoob plaws Tebchaws Europe. Cov koom haum tsim qauv hauv tebchaws sib txawv yuav ua ntej tus qauv nrog cov lus luv luv hauv tebchaws, tab sis cov ntsiab lus tseem ceeb ntawm tus qauv tseem zoo ib yam.
Cov ntu hollow tuaj yeem raug cais ua voj voog, square lossis rectangular, lossis elliptical.
Tsis tas li ntawd vim tias nws yog ib qho txheej txheem kub tiav raws li EN 10210, cov lus luv hauv qab no tuaj yeem siv tau.
HFCHS= kub tiav lawm voj voog hollow seem;
HFRHS= kub tiav lawm square lossis rectangular hollow sections;
HFEHS= cov seem elliptical hollow kub tiav lawm.
Puag ncig: Sab nraud txoj kab uas hla mus txog 2500 hli;
Phab ntsa thicknesses txog li 120 hli.
Tau kawg, tsis muaj txoj hauv kev los tsim cov raj ntawm qhov loj me thiab phab ntsa no yog tias siv cov txheej txheem ERW vuam.
ERW tuaj yeem tsim cov raj txog li 660mm nrog phab ntsa tuab ntawm 20mm.
Cov hlau tuaj yeem tsim los ntawm kev sivseamless los yog vuamtxheej txheem.
Ntawm covcov txheej txheem vuam, cov txheej txheem vuam feem ntau suav nrogERW(kev vuam hluav taws xob tsis kam) thiabSAW(submerged arc vuam).
Ntawm lwm tus,ERWyog ib txoj kev vuam uas txuas cov khoom hlau ua ke los ntawm kev siv cua sov thiab siab. Txoj kev no siv tau rau ntau yam khoom siv thiab tuab thiab ua rau muaj kev vuam zoo.
SAW, ntawm qhov tod tes, yog ib txoj kev vuam uas siv cov kua nplaum granular los npog lub arc, uas muab kev nkag mus tob dua thiab zoo dua qhov vuam zoo thiab tshwj xeeb tshaj yog tsim rau vuam cov phaj tuab.
Tom ntej no, yog cov txheej txheem ERW, uas yog cov txheej txheem tsim khoom zoo heev uas siv dav los tsim ntau yam yeeb nkab hlau thiab cov profile.
Yuav tsum nco ntsoov tias rau cov seem tsis muaj hlau thiab cov khoom me me uas ua los ntawm cov txheej txheem vuam, kev kho vuam tsis raug tso cai tsuas yog kev vuam submerged arc xwb.
Cov Qauv JR, JO, J2 thiab K2 - kub tiav lawm,
Lub zog tsawg kawg nkaus ntawm S355J2H steel yeeb nkab tsis ruaj khov, nws yuav hloov pauv nrog cov phab ntsa sib txawv.
Tshwj xeeb, lub zog tso zis ntawm S355J2H raug teeb tsa raws li tus qauv thaum lub phab ntsa tuab tsawg dua lossis sib npaug rau 16 hli, tab sis thaum lub phab ntsa tuab nce ntxiv, lub zog tso zis yuav raug txo qis, yog li tsis yog txhua lub yeeb nkab hlau S355J2H tuaj yeem ncav cuag lub zog tso zis tsawg kawg nkaus ntawm 355MPa.
