Iziteshi ze-UPN: Ubukhulu, Isisindo kanye namazinga e-EN 10279

Iziteshi ze-UPN- obeye aziwe njengoIziteshi zensimbi ze-U-profilethola ukusetshenziswa kwazo emisebenzini yensimbi yesakhiwo ngenxa yokuhambisana kwazo ezixazululweni zezakhiwo, amahholo ezimboni, amabhuloho, ozimele bemishini, njll.isakhiwo esinomumo we-U esakhiwe ngaphambiliniizakhi ezinobukhulu obuthile kanye nesisindo, ezenzelwe ukuletha ukusebenza okubikezelwayo ezinhlelweni zobunjiniyela.

I-UPN

Izindinganiso ze-EN 10279 kanye ne-DIN

Iziteshi ze-UPNzisekelwe ezilinganisweni zaseYurophu ze-DIN 1026‑1 kanye nokubekezelelana kwe-EN 10279, futhi zifanele ukwakhiwa ngo-2026. Lezi zinhlaka ziphoqelela ikhwalithi kanye nokushintshana kwento ngayinyeIsigaba se-UPNngokwezinga layo lokuphakama (h), ububanzi be-flange (b), ubukhulu bewebhu (tw) kanye nobukhulu be-flange (tf).

Osayizi Nezisindo Zesiteshi se-UPN

OkujwayelekileOsayizi beziteshi ze-UPNAma-UPN 50, UPN 80, UPN 120, UPN 180 kanye ne-UPN 240, isisindo siyahlukahluka kusuka ku-5,6 kg/m UPN 50 kuya ku-33,2 kg/m ku-UPN 240. Usayizi we-UPN ongu-120 wemishayo ungabamba okungaphezu kuka-1,3KN ngemitha futhi kumasayizi amakhulu njenge-UPN 300 nangaphezulu angafinyelela okungaphezu kuka-40 KN ngemitha kuye ngokuthi i-flange kanye ne-web ziqine kangakanani.

Ukubaluleka Kokuqiniswa

Ukubekezelelana okuvumelekile kuUbukhulu besiteshi se-UPNkanye nezakhiwo zesigaba zichazwe yi-EN 10279 standard. Kubalulekile ukuthi abakhiqizi beziteshi zensimbi balingane, ngakho-keIziteshi zensimbi ze-ENzijwayelekile ukuze kube lula ukusebenzisana, okubalulekile futhiimisebenzi yesakhiwo sensimbilapho kuphoqelekile khona ukuvunyelwa ukubekezelelana okuthile ngobukhulu.

Isiteshi se-UPN

Amabanga Ezinto Ezibalulekile Zeziteshi ze-UPN

Izingxenye ze-UPN zivame ukukhiqizwa ngama-hot rolled steel grades njenge-S235JR, S275JR kanye ne-S355JR futhi zitholakala ngamazinga amaningi okuqina kanye nokuguquguquka okwenza zikwazi ukusetshenziswa ezindaweni eziningi zokwakha ezahlukene kungakhathaliseki ukuthi zezakhiwo zezimboni noma ingqalasizinda yomphakathi.

Iziteshi ze-UPN ekwakhiweni kwensimbi

Ngokufigqiwe,Iziteshi ze-UPNziyisici esiyisisekelo kwesimanjeukwakhiwa kwensimbi, kanye nokusekelwa okuzinzileIzindinganiso zobukhulu nokubekezelelana ze-EN 10279ukuqinisekisa ukuthembeka nokusebenza kahleamaphrojekthi azayo ka-2026.
