TS EN 10219 Cov Qauv European rau Kev Ntsuas Cov Khoom Siv Hluav Taws Xob
EN 10219 yog cov qauv ntsuas rau cov khoom siv hlau tsim los ntawmEuropean Standardization Organization (CEN). Nws qhia txog cov kev xav tau thiab kev sim rautxias- ua welded structural steel raj, tsom rau txhua yam khoom, tshuaj muaj pes tsawg leeg, thiab cov yam ntxwv ntawm lub cev. Raws li cov qauv ntsuas tseem ceeb rau kev ua raws li European cov qauv, EN 10219 ua kom zoo thiab kev nyab xeeb ntawm cov khoom steel.
1. Mechanical Performance Testing
EN 10219 txoj caikev ntsuam xyuas tensilethiabcuam tshuam kev kuajlos ntsuas lub zog, ductility, thiab toughness.
Tensile Tests: Ntsuas tawm lub zog, tensile lub zog, thiab elongation los xyuas kom meej tsis kam mus deformation nyob rau hauv load.
Impact Tests: Txheeb xyuas qhov hnyav hauv qhov hnyav hnyav (piv txwv li, Charpy V-qhov ntsuas qhov ntsuas) txhawm rau tiv thaiv cov pob txha tawg.
Piv txwv: Rau cov raj uas muaj thicknesses tsawg dua los yog sib npaug rau 16 hli, qhov tsawg kawg nkaus lub zog ntawm27J ntawm -20 degreeyuav tsum tau.
2. Chemical Composition & Physical Properties
Tshuaj ntsuam xyuas: Txheeb xyuas kev ua raws li cov kev txwv (piv txwv li,C Tsawg dua lossis sib npaug li 0.22%, P / S Tsawg dua lossis sib npaug li 0.035%rau S235JR qib sib npaug).
Kev kuaj lub cev: suav nrog kev kuaj xyuas hardness, corrosion kuj (xws li, tshuaj tsuag ntsev), thiab kev txheeb xyuas qhov ntev (xws li, phab ntsa thickness kam rau ua:±10%).
3. Cov txheej txheem ntau lawm yuav tsum tau ua
Tus txheej txheem tswj nrujkev tswj kev tsim khoom, suav nrog:
Vuam Zoo: Ultrasonic kuaj (UT) lossis kuaj hluav taws xob (RT) rau kev ncaj ncees.
Txias-Txoj kev tsim: Xyuas kom cov khoom lis dej ntws sib haum nrog cov txheej txheem kev ntxhov siab, txhawb kev qaug zog.
4. Qhov tseem ceeb hauv kev yuav khoom
Kev Ua Raws Cai: Cov neeg yuav khoom yuav tsum txheeb xyuas EN 10219 daim ntawv pov thawj kom ntseeg tau tias cov khoom ua tau rawsEU Kev Tswj Khoom Siv Khoom Siv (CPR).
Sib piv Advantage: Tsis zoo liTS EN 10025(rau kub- dov steel), EN 10219 yog tsim rautxias- ua welded raj, muab siab dua precision rau lub teeb yuag.
