Chaw Tsim Khoom thiab Mob
ASTM A213 T12 cov kav hlau yuav tsum ua los ntawm cov txheej txheem seamless thiab yuav tsum yog kub tiav lossis txias tiav, raws li tau teev tseg.
Kev Kho Mob Kub
Txhua lub kav hlau T12 yuav tsum tau kho cua sov.
Cov txheej txheem kho cua sov uas tso cai suav nrog full los yog isothermal annealing, normalizing thiab tempering, los yogkev ua kom sov subcritical.

Txhua lub raj yuav tsum raug rau qhov kev sim hluav taws xob tsis puas tsuaj lossis qhov kev sim hydrostatic.Hom kev sim uas yuav siv yuav tsum yog nyob ntawm qhov kev xaiv ntawm tus neeg tsim khoom, tshwj tsis yog tias tau teev tseg lwm yam hauv daim ntawv xaj yuav khoom.
Cov txheej txheem sim yuav tsum tau ua raws li cov kev cai ntawm Tshooj 25 thiab 26 ntawm ASTM A1016.
ASTM A213 T12 cov yeeb nkab loj thiab phab ntsa tuab feem ntau yog muab nrog sab hauv txoj kab uas hla txij li 3.2 hli mus rau sab nraud txoj kab uas hla ntawm 127 hli, thiab qhov tsawg kawg nkaus phab ntsa tuab ntawm 0.4 hli mus rau 12.7 hli.
Lwm qhov loj ntawm T12 steel yeeb nkab kuj tseem tuaj yeem muab tau, muab tias txhua yam kev cai ntawm ASTM A213 tau ua tiav.
ASTM A213 T12 alloy steel seamless tubes feem ntau yog siv rau hauv qhov kub thiab txias thiab qhov siab siab. Cov ntawv thov ib txwm muaj xws li
1. Cov Tshuab Ua Kub Thiab Cov Tshuab Ua Kub Dua
