ASTM A249 Tube Tensile thiab Hardness Requirements

ASTM A249 Mechanical Properties

Thaum nws los txog rau mechanical zog ntawmASTM A249 tubes, tus qauv qhia cov kev cai tshwj xeeb rau ob qho tib si tensile lub zog thiab hardness. Tensile thiab hardness xav tau ntawmASTM A249 welded rajNws yog ib qho tseem ceeb los xyuas kom meej lawv cov kev ua tau zoo thiab kev ntseeg tau. Cov neeg tsim khoom thiab cov neeg siv cov raj no yuav tsum xyuas kom meej tias lawv ua tau raws li cov kev cai tshwj xeeb uas tau teev tseg hauv tus qauv los lav lawv qhov tsim nyog rau kev siv boiler, superheater, kub exchanger, los yog condenser daim ntaub ntawv.

Tensile Strength Requirements

Lub zog tensile ntawm lubASTM A249 stainless hlau rajyog qhov ntsuas qhov siab tshaj plaws uas lub raj tuaj yeem tiv taus ua ntej nws pib deform lossis tsis ua haujlwm. Raws li tus qauv, cov raj yuav tsum ua tau raws li qhov yuav tsum tau muaj zog tensile yam tsawg kawg nkaus raws li lawv cov qib.

Hardness Requirements

Ntawm qhov tod tes, hardness yog txhais raws li kev ntsuas ntawm yuav ua li cas resistant aASME SA249 khoomyog rau localized deformation, tshwj xeeb yog yas deformation los yog indentation. Tus qauv qhia txog ob hom kev ntsuas hardness uas tuaj yeem ua tau ntawm cov raj - Rockwell hardness test thiab Brinell hardness test.
