Daim ntawv thov
Lub Hwj Chim Siab & Boilers: Nws qhov tseem ceeb yog siv hauv kev tsim cov khoom xws li nruas thiab plhaub rau siab - qhov kub thiab txias kev pab cuam nyob rau hauv industrial boilers thiab siab hlab ntsha, enduring ntev - lub sij hawm thermal stress.
Petrochemical & Chemical Plants: Zoo tagnrho rau refinery reactors thiab chemical processing tanks -nws siab -kub corrosion kuj suits cov txheej txheem hnyav.
Fais fab Generation: Siv nyob rau hauv thermal fais fab nroj tsuag rau boilers, tshav kub exchangers thiab chav kav, txhawb kev ruaj khov zog ntau lawm.
Roj & Roj: Pom muaj nyob rau hauv cov khoom siv hauv ntug dej hiav txwv, qaub- cov chaw cia tso tsheb hlau luam thiab lub taub hau iav, yoog raws li cov khoom siv tawv tawv.
Thaum tshav kub kub Exchangers & Condensers: Tsim kom muaj cua sov hloov mus rau hauv cov ntawv raj thiab cov plhaub, ua haujlwm rau ntau hom kev lag luam.
Qhov zoo
Siab -Tsub Muaj Zog:Khaws cov qauv kev ncaj ncees thiab cov khoom siv kho tshuab ntawm qhov kub siab, qhov tseem ceeb rau kev siv hauv kev lag luam.
Corrosion Resistance:Chromium cov ntsiab lus muab kev txhim kho kev tiv thaiv rau kev xeb thiab oxidation, tshwj xeeb tshaj yog nyob rau hauv siab - cua sov ib puag ncig.
Weldability:Zoo weldability tso cai rau fabrication siv cov pa txoj kev uas tsis muaj compromising txhua yam khoom, ua tsaug rau nws tswj chemistry.
Thermal stability:Resistant embrittlement thaum lub sij hawm ntev thermal cycling, ua rau lub neej ntev dua.
Versatility:Haum rau cov khoom siv hluav taws xob, cov kav dej, cov tso tsheb hlau luam, thiab cov boilers hauv cov roj, roj, thiab tshuaj lom neeg kev lag luam.
Tus nqi -Kev ua tau zoo:Kev ua haujlwm ruaj khov thiab txhim khu kev qha txo lub sijhawm poob thiab kev saib xyuas, muab sijhawm ntev - cov txiaj ntsig kev lag luam.

1.Sa 387 Gr 5 Cl 1 txawv ntawm SA 387 Gr 5 Cl 2 li cas?
Qhov sib txawv tseem ceeb nyob hauv lub zog tensile-Cl 2 muaj lub zog tensile ntau dua li Cl 1, ua rau nws tsim nyog rau kev xav tau ntau dua - cov kev pabcuam siab.
2.Yog SA 387 carbon steel?
Weldable carbon steel daim hlau rau cov hlab ntsha siab thiab boilers siv nyob rau hauv siab kub. Cov khoom siv tau txais txiaj ntsig los ntawm kev ntxiv chromium thiab molybdenum uas muab cov hlau ntau dua corrosion tsis kam thiab tiv taus cua sov.
3.Dab tsi yog cov khoom tseem ceeb ntawm SA 387 Gr 5 Cl 1?
Nws nta zoo siab - kub lub zog, oxidation kuj, txhim khu kev qha weldability thiab creep tsis kam, haum rau ntev - lub sij hawm ua hauj lwm nyob rau hauv siab kub.
