EN 10255 Cov yeeb nkab

Tianjin Lefin Industrial Co., Ltd yog ib qho ntawm cov tuam ntxhab thiab cov muag khoom ntawm en10255 yeeb nkab hauv Suav teb. Thov koj xav tias dawb mus yuav cov yeeb nkab zoo en10255 los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.

EN 10255 yog tus qauv European rau cov tsis yog - alloy steel kav tsim nyog rau vuam thiab xov ua haujlwm, feem ntau yog siv rau hauv qis - cov kua xa dej siab hauv kev tsim kho thiab kev lag luam. Cov lus hauv qab no tuaj yeem pab koj nkag siab sai sai rau nws cov ntsiab lus tshwj xeeb.

• Dimensions thiab tolerances:

Cov txheej txheem muaj kev cai nruj txwv tsis pub sib txawv rau sab nraud txoj kab uas hla, phab ntsa thickness thiab ncaj ntawm cov kav hlau. Piv txwv li, sab nraud txoj kab uas hla feem ntau yuav tsum tau tswj nyob rau hauv ± 0.75% los xyuas kom meej lub sealing ntawm cov yeeb nkab kev sib txuas thiab qhov yooj yim ntawm kev tsim kho.

• Khoom siv thiab khoom:

Tus qauv xav kom cov yeeb nkab steel yog ua los ntawm cov hlau tsis yog - alloy steel, thiab qib steel feem ntau yog S195T. Nws cov tshuaj muaj pes tsawg leeg yog tus cwj pwm los ntawm qhov qis - carbon tsim, uas ua kom cov vuam zoo heev thiab kev ua haujlwm threading. Nyob rau hauv cov nqe lus ntawm txhua yam khoom, lub zog tawm los yuav tsum tsis pub tsawg tshaj 195 MPa, lub tensile lub zog ntawm 320 thiab 520 MPa, thiab elongation feem ntau yuav tsum tsis pub tsawg tshaj 20%.

• Kev kho deg thiab yeeb nkab kawg daim ntawv:

Cov kav dej tuaj yeem raug kho raws li qhov xav tau, xws li cov yeeb nkab dub, roj txheej, kub -dip galvanizing, thiab lwm yam, txhawm rau txhim kho corrosion. Cov yeeb nkab kawg tuaj yeem ua tiav rau hauv ntau hom xws li cov xaus, threaded los yog nrog lub qhov (socket) thiab spigot pob qij txha, hloov mus rau ntau txoj kev sib txuas xws li vuam thiab threaded kev twb kev txuas.

Thaum xaiv thiab siv EN 10255 steel kav hauv cov haujlwm tiag tiag, cov hauv qab no tuaj yeem txiav txim siab:

• Xaiv cov series raws li kev xav tau siab:

Rau cov tshuab uas muaj lub siab ua haujlwm qis lossis lub hom phiaj dav dav, qhov nruab nrab - cov kav dej loj tuaj yeem raug xaiv kom txuag nqi. Rau cov xwm txheej uas yuav tsum tau muaj lub zog ntau dua lossis tuaj yeem tiv taus siab dua, hnyav -cov kav dej yuav tsum raug xaiv.

• Xaiv txoj kev tiv thaiv raws li ib puag ncig:

Nyob rau hauv qhov chaw ntub dej los yog yooj yim corrosive, cov kav dej uas tau dhau los kub -dip galvanizing kev kho mob yuav tsum tau muab qhov tseem ceeb los ua kom lawv lub neej ua haujlwm tau zoo.

• Them mloog mus rau txoj kev sib txuas:

Yog hais tias qhov project yuav tsum tau disassembly nquag los yog ntawm - qhov chaw vuam tsis yooj yim, cov kav dej uas muaj threaded kawg tuaj yeem xaiv tau. Yog tias lub kaw lus feem ntau txuas nrog vuam, tiaj tus - cov kav dej kawg tuaj yeem xaiv tau.

• Cov ntsiab lus tseem ceeb rau kev yuav khoom thiab kev lees txais:

Thaum ua kev yuav khoom, tus qauv version, qib steel, series hom, kev kho deg, thiab lwm yam yuav tsum tau txhais kom meej. Thaum lub sijhawm lees txais, cov neeg xa khoom tuaj yeem xav tau los muab cov ntaub ntawv pov thawj uas ua tau raws li EN 10204 tus qauv, thiab kev kuaj xyuas tuaj yeem ua tiav ntawm qhov ntev, phab ntsa tuab thiab qhov zoo ntawm qhov chaw.
