Cov ntawv thov tseem ceeb
Roj & Roj:
A537 Chav Kawm 3 yog dav siv nyob rau hauv cov roj thiab roj sector rau lub tsev siab hlab ntsha, cia tso tsheb hlau luam, separators, thiab piping systems. Cov khoom no feem ntau ua haujlwm nyob rau hauv siab thiab kub, tuav cov roj crude, nkev roj, thiab ntau yam hydrocarbon kua. Cov hlau sib xyaw ua ke ntawm lub zog thiab lub zog ua rau nws tsim nyog rau ob qho tib si onshore thiab offshore installation, qhov kev ntseeg siab thiab kev tiv thaiv rau cov pob txha tawg yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm tas mus li.
Petrochemical Kev Lag Luam:
Hauv cov nroj tsuag petrochemical, A537 Chav Kawm 3 yog ua haujlwm hauv kev tsim cov reactors, cov txheej txheem tso tsheb hlau luam, thiab ntau yam khoom siv ua haujlwm. Cov koog no koom nrog hauv cov kev cuam tshuam thiab kev sib cais uas raug cov khoom siv rau kev thauj khoom cyclic, thermal stress, thiab corrosive ib puag ncig. Cov hlau muaj peev xwm tswj tau nws cov khoom siv kho tshuab ntawm qhov kub siab ua rau nws yog qhov kev xaiv zoo tshaj plaws los ua kom lub neej ua haujlwm ntev thiab txo qis qis hauv cov chaw tsim khoom tseem ceeb.
Kev tsim hluav taws xob:
Hauv kev lag luam tsim hluav taws xob, A537 Chav Kawm 3 yog siv rau cov khoom hauv boilers thiab chav tshuab, nrog rau cov khoom siv siab thiab cua sov- hloov chaw. Cov ntawv thov no xav tau cov ntaub ntawv uas tuaj yeem tiv taus siab -siab chav thiab rov ua dua thermal cycling. Cov hlau zoo creep kuj thiab toughness pab xyuas kom meej cov txheej txheem ntawm boiler seem thiab cov khoom txuam, pab rau tag nrho cov efficiency thiab kev nyab xeeb ntawm fais fab nroj tsuag.
Kev ua tshuaj lom neeg:
Rau cov chaw ua tshuaj lom neeg, A537 Chav Kawm 3 yog siv rau hauv kev tsim cov tank thiab cov hlab ntsha rau nruab nrab - cia siab thiab tuav ntau yam tshuaj. Cov hlab ntsha no tuaj yeem raug rau qhov kub thiab txias thiab muaj peev xwm corrosive media, nyob ntawm cov txheej txheem tshwj xeeb. Cov hlau cov khoom sib npaug ua rau nws tsim nyog rau khaws cia ob qho tib si kua thiab cov tshuaj gaseous hauv kev siv

ASTM A537 yog dab tsi?
ASTM A537 specification yog tus qauv Specification rau Siab Vessel Phaj, Thaum tshav kub kub-Kho, Carbon-Manganese-Silicon Steel siv nyob rau hauv daim ntawv thov ntawm fusion welded siab hlab ntsha thiab cov qauv.
Dab tsi yog qhov kev kho cua sov rau A537 Chav Kawm 3?
A537 Chav Kawm 3 feem ntau yog muab nyob rau hauv qhov normalized thiab tempered mob. Normalization refines lub grain qauv thiab txhim kho toughness, thaum tempering txo hardness thiab residual stresses, ua rau ib tug zoo ua ke ntawm lub zog thiab ductility.
