Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm S355JR thiab S355J2H steel qib raws li EN 10219 tus qauv?
A: Qhov tseem ceeb ntawm qhov sib txawv yog nyob ntawmcuam tshuam kev ntsuas kubthiab daim ntawv thov Scope.S355 JRyuav tsum tau ua kom muaj kev cuam tshuam ntawm chav tsev kub (+20℃) nqus qhov tsawg kawg nkaus ntawm 27 Joules, ua rau nws raug nqi heev - siv tau rau cov qauv sab hauv tsev lossis cov qauv sab nraum zoov.S355J2Hkev tswj xyuas qhov cuam tshuam rau kev sim mus rau -20℃thiab suav nrog qhov yuav tsum tau ua "H" rau cov ntawv pov thawj hollow seem, ua kom zoo rau qhov hnyav sub- xoom huab cua lossis dynamic, tawg-tshem tawm sab nrauv engineering.
Q: Puas tuaj yeem EN 10219 S355JR structural steel round kav siv tau raws li siab - cov kav dej siab?
A: Tsis yog EN 10219 yog kev mob siab rautus qauv qauvoptimized rau structural engineering, architectural framing, thiab load-cov kabmob. Nws tsis tas yuav tsum ntsuas hydrostatic siab thaum lub sij hawm zeb kab ntau lawm. Yog tias koj qhov phiaj xwm cuam tshuam txog kev thauj khoom siab - dej siab, roj av, lossis hydrocarbons, koj yuav tsum qhia kom meej siab - ntsuas cov kav dej xws liTS EN 10217los yogAPI 5L, uas tswj siab -cov kua dej tuav cov kev ntsuas siab.
Q: Yuav ua li cas koj lub zeb tiv thaiv cov qauv puag ncig steel kav los ntawm corrosion thaum lub sij hawm ntev dej hiav txwv hla?
A: Txhawm rau tiv thaiv cov hlau tsis zoo los ntawm cov av noo siab thiab ntsev- huab cua hauv hiav txwv thaum thauj mus los, peb kho 100% ntawm peb cov kav xa tawm nrog lub siab - dej affinity - tiv thaiv los tiv thaiv - xeb roj lossis lub teeb dub kua roj vanish txheej. Rau qhov ntev tshaj plaws nyob rau hauv kev txhoj puab heev sab nraum zoov lossis ntug hiav txwv ib puag ncig, peb pom zoo kom qhia peb lub HoobkasKub-Dip Galvanized (HDG)tiav, uas tsim ib qho metallurgical zinc barrier uas tiv thaiv oxidation rau xyoo lawm.
