Cov Kev Sib Txuas UPN: Qhov Loj, Qhov Hnyav thiab EN 10279 Cov Qauv

Cov channel UPN— kuj hu uaU-profile steel channelsnrhiav lawv daim ntawv thov hauv cov hlau ua haujlwm vim lawv qhov sib xws hauv cov kev daws teeb meem rau cov tsev, cov chaw ua haujlwm, cov choj, cov thav duab tshuab, thiab lwm yam. Lawv yogCov qauv U-puab uas tau tsim ua ntejcov khoom uas muaj qhov ntev thiab qhov hnyav tshwj xeeb, tsim los xa cov kev ua tau zoo kwv yees tau hauv kev siv engineering.

UPN

EN 10279 thiab DIN Cov Qauv

Cov channel UPNyog raws li European qhov ntev ntawm DIN 1026‑1 thiab kev kam rau siab ntawm EN 10279, thiab tsim nyog rau kev tsim kho hauv xyoo 2026. Cov kev ntsuas no ua kom muaj qhov zoo thiab kev sib pauv ntawm txhua tusntu UPNnyob rau hauv cov nqe lus ntawm nws qhov siab (h), flange dav (b), web thickness (tw) thiab flange thickness (tf).

Qhov Loj thiab Qhov Hnyav ntawm UPN Channel

Tus QauvQhov loj ntawm UPN channelyog UPN 50, UPN 80, UPN 120, UPN 180 thiab UPN 240, qhov hnyav sib txawv ntawm 5,6 kg/m UPN 50 txog 33,2 kg/m rau UPN 240. UPN loj 120 beams tuaj yeem tuav ntau dua 1,3KN ib m thiab rau cov loj dua xws li UPN 300 thiab siab dua tuaj yeem ncav cuag ntau dua 40 KN ib 'meter' nyob ntawm qhov tuab ntawm flange thiab web.

Qhov Tseem Ceeb ntawm Kev Ua Tus Qauv

Cov kev txwv ntawm kev lees txais tolerancesQhov ntev ntawm UPN channelthiab cov khoom seem yog teev los ntawm tus qauv EN 10279. Nws yog ib qho tseem ceeb uas cov neeg tsim khoom en steel channel yuav tsum sib npaug, yog li ntawdEN cov kav hlautau raug teeb tsa tus qauv los pab txhawb kev siv sib pauv tau, uas tseem ceeb raucov qauv hlau ua haujlwmqhov twg nws yog qhov yuav tsum tau ua kom tau qee qhov kev kam rau siab hauv qhov ntev.

Cov Qib Khoom Siv rau UPN Channels

Cov ntu UPN yog cov feem ntau tsim tawm hauv cov hlau kub dov xws li S235JR, S275JR thiab S355JR thiab muaj ntau theem ntawm lub zog thiab ductility uas ua rau lawv siv tau rau ntau yam kev siv hauv kev tsim kho txawm tias yog rau cov tsev lag luam lossis cov chaw tsim kho vaj tse.

Cov channel UPN hauv kev tsim kho hlau

Hauv kev xaus,Cov channel UPNyog ib qho tseem ceeb hauv kev lag luam niaj hnub nokev tsim kho hlau, nrog rau kev tsim kho zooEN 10279 qhov ntev thiab kev kam rau siabua kom ntseeg tau tias muaj kev ntseeg siab thiab kev ua tau zoo raucov haujlwm xyoo 2026 uas yuav los txog.
