EN 10219 S420MH Structural Steel yog dab tsi?
Yuav kom nkag siab tias yog vim li cas cov khoom no yog ib qho tseem ceeb hauv kev tsim kho choj, nws yog ib qho tseem ceeb rau kev txiav txim siab nws tus qauv European alphanumeric designation:
- TS EN 10219:Cov txheej txheem European qhia txog cov txheej txheem kev xa khoom rau txias- tsim welded structural hollow seem ntawm tsis yog- alloy thiab nplua - nplej hlau.
- S:Txheeb xyuas cov khoom siv raws li qib siab ntawm cov qauv steel.
- 420:Qhia txog qhov tsawg kawg nkaus tawm lub zog ntawm420 MPa rau(rau phab ntsa thicknesses 16 hli), outperforming standard S235 los yog S355 qib.
- M:Qhia tau tias cov hlau tau dhau lawmThermomechanically Rolled (TMCP)ua, optimizing grain refinement rau superior weldability thiab toughness.
- H:Stands rau "Hollow Section," suav nrog square (SHS), rectangular (RHS), thiab ncig (CHS) profiles.
Cov txiaj ntsig zoo ntawm S420MH hauv kev tsim choj
- High Yam Tsawg Tshaj Tawm Lub Zog ntawm 420 MPa:Pab kom nyias nyias phab ntsa thickness specification thiab lub teeb yuag qauv tsim, txiav tag nrho steel noj thaum tswj sib npaug load- bearing peev.
- TMCP Thermo-Mechanical Controlled Rolling Microstructure:Tsawg carbon sib npaug muaj pes tsawg leeg muab tau zoo heev ntawm - qhov chaw weldability, tshem tawm cov kev xav tau ua ntej rau feem ntau cov txheej txheem vuam.
- Superior Low-Tsub Impact Toughness:Certified Charpy cuam tshuam kev ua tau zoo ntawm -20 degree, zoo zam kev puas tsuaj rau pob txha tawg nyob rau hauv cov kev pab cuam txias ambient.
Cov ntawv thov tseem ceeb hauv Bridge Engineering
Ua tsaug rau lawv cov qauv kev ua haujlwm siab, EN 10219 S420MH hollow seem tau nthuav dav siv thoob plaws cov choj tseem ceeb:
- Cov neeg taug kev thiab caij tsheb kauj vab:Siv raws li qhov tseem ceeb tshaj nyiaj siv ua haujlwm arches, tes taw qhia, thiab lub ntsiab txhawb nqa trusses los tsim lub teeb yuag, elegant taug kev.
- Nyob Cable thiab Suspension Choj:Deployed li hnyav ntsug pylons, anchorage ntauwd braces, thiab aerodynamic stiffening girders.
- Highway thiab Railway Truss Choj:Siv raws li sab hauv kab pheeb ces kaum thiab ntsug web cov tswv cuab nyob rau hauv complex structural trusses, qhov twg siab cyclic loading kuj tseem ceeb heev.
- Choj Foundation Casing & Pilings:Circular hollow sections ($CHS$) yog tsav mus tob li siab -muaj peev xwm txheej txheem casings los yog kev sib txhuam pawg rau dej hla thiab ntug hiav txwv piers.
Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm EN 10210 thiab EN 10219 rau S420MH steel?
A: Thawj qhov sib txawv yog nyob rau hauv txoj kev tsim thiab kub.TS EN 10210tswj hwmkub -ua tiavhollow seem, uas zoo li dawb los ntawm sab hauv residual stresses.TS EN 10219tswj hwmtxias - tsimwelded hollow seem. Thaum txias -cov qauv tsim yog tus nqi ntau dua- ua haujlwm tau zoo thiab muaj qhov ua tau zoo tshaj plaws, cov kws ua haujlwm yuav tsum suav rau cov kev ntxhov siab nyob hauv cheeb tsam thaum lub sij hawm tsim qauv.
Q: Cov txheej txheem TMCP tau txais txiaj ntsig li cas S420MH hlau?
A: Thermomechanically Controlled Processing (TMCP) ua ke nrog kev tswj xyuas qhov kub thiab txias thiab tshuab dov hauv lub zeb. Qhov no tsim kom muaj kev ua kom zoo, zoo ib yam zoo -grain microstructure. Nws tso cai rau cov hlau kom ua tiav nws cov ultra- siab 420 MPa tawm lub zog thaum tswj cov pa roj carbon tsawg, ua rau thaj chaw zoo dua qub dua li cov cua sov ib txwm siv- kho steels.
Q: Dab tsi tsis yog -Kev Ntsuas Kev Ua Phem (NDT) yog qhov yuav tsum tau ua rau cov kav dej txuas - qib?
A: Muab hais tias cov khoom siv txuas txuas tau raug tshuaj xyuas nruj rau pej xeem kev nyab xeeb, txhua lub yeeb nkab batch tau txais kev lees paub zoo. Qhov no suav nrogKev Ntsuas Ultrasonic Nruam (UT)los yog Eddy Tam sim no scans raws li weld seam kom pom cov voids sab hauv, ntsuas qhov ntev rau qhov ncaj, thiab yuav tsum tau uaHydrostatic Pressure lossis Electromagnetic Testtxhawm rau txheeb xyuas cov qauv kev ncaj ncees nyob rau hauv siab.
Q: Cov seem hollow no tiv thaiv ntev npaum li cas -ib puag ncig corrosion?
A: Txhawm rau kom lub neej ntev tshaj li 50 txog 100 xyoo, S420MH profiles tuaj yeem raug txiav txim nrog ntau cov txheej tiv thaiv. Cov kev xaiv muaj xws li kev lag luam kub-dip galvanization, zinc-nplua nuj epoxy primers, siab-cov coated polyurethane tiav, los yog cov txheej txheem tshwj xeeb sab nraud xws li 3LPE lossis FBE rau cov qauv hauv av / hauv qab dej.
