Daim ntawv thov
Siab Vessels & Industrial Boilers
Nws yog siv los tsim cov ntsiab lus tseem ceeb xws li hnyav- lub luag haujlwm boiler nruas, tuab- phab ntsa siab ntawm lub plhaub, siab - lub taub hau siab thiab lub tshuab nqus dej. Cov khoom no tau siv dav hauv cov chaw tsim hluav taws xob, loj- cov chaw ua kom zoo nkauj thiab cov chaw tsim tshuaj lom neeg uas ua haujlwm nyob rau hauv kev ua haujlwm tsis tu ncua siab - kub thiab siab - siab, ua kom ntev - lub sij hawm kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv.
Petrochemical & Chemical Processing Khoom
Cov khoom siv zoo tagnrho rau kev tsim cov khoom siv hluav taws xob, siab -siab reactors thiab siab -kub txheej txheem piping systems hauv petrochemical thiab tshuaj nroj tsuag. Cov khoom siv no yog ua haujlwm los tuav ntau yam txheej txheem corrosive media xws li kua qaub lossis alkaline kua. Nrog nws zoo heev creep tsis kam mus txog 550 degree, cov khoom muaj peev xwm tiv taus ntev thermal kev nyuaj siab yam tsis muaj deformation, uas yog ib qho tseem ceeb rau kev tswj cov efficiency thiab kev ntseeg siab ntawm tas mus li ntau lawm kab.
Sour me ntsis -kev pab Roj & Roj Iav
Ua tsaug rau nws cov kev tiv thaiv corrosion zoo dua piv rau cov hlau, SA 387 Gr 5 Cl 1 yog qhov zoo- haum rau kev tsim cov khoom siv tseem ceeb hauv cov qaub qaub- pabcuam roj thiab roj ib puag ncig, suav nrog roj- cov kua cais tawm, kaw lub tank thiab ntawm - cov kab sib sau ua ke. Cov khoom no yog tsim los tiv tauj cov xov xwm uas muaj tsawg-concentration ntub hydrogen sulfide (H₂S), zoo tiv thaiv sulfide kev nyuaj siab corrosion cracking thiab ncua lub neej kev pab cuam ntawm cov cuab yeej.
Thermal Processing Systems
Nws ua haujlwm ua cov khoom siv txhim khu kev qha rau kev tsim khoom siab -kub thermal ua cov khoom siv hauv cov ntawv thiab cov ntawv mills, xws li cov cua sov rauv hauv ob sab phlu, cov cua sov rov qab thiab cov kav dej. Cov khoom siv oxidation zoo heev tso cai rau nws ua haujlwm ruaj khov hauv qhov siab - cua sov, av noo thiab corrosive huab cua zoo li cov txheej txheem ntawm cov ntaub so ntswg thiab ntawv, txo qhov zaus ntawm kev tu thiab hloov khoom siv.

1.Qhov kev lag luam twg yog SA 387 Gr 5 Cl 1 siv hauv?
SA 387 Gr 5 Cl 1 alloy steel feem ntau yog siv rau hauv cov roj & roj, petrochemical, thiab hluav taws xob tsim kev lag luam rau siab -kub siv xws li cov hlab ntsha, boilers, kub exchangers, thiab kav dej, ua tsaug rau nws zoo heev corrosion kuj thiab lub zog ntawm siab kub. Nws tseem pom muaj nyob rau hauv cov nroj tsuag tshuaj, marine, thiab shipbuilding rau qhov xav tau ib puag ncig uas yuav tsum tau kub thiab corrosion kuj.
2.Dab tsi yog cov kev siv ntawm SA 387 Gr 5 Cl 1?
Cov ntawv thov muaj xws li boiler nruas, lub plhaub siab ntawm lub plhaub, cov ntawv kub hloov raj, cov reactors reactors thiab siab -kub txheej txheem piping Cheebtsam.
