Qhov zoo
High -Kev Ua Haujlwm Kub: Ua kom muaj zog thiab kev ncaj ncees ntawm qhov kub siab, tiv thaiv kev nkag siab thiab thermal stress.
Corrosion & Oxidation Resistance: Chromium cov ntsiab lus muab kev tiv thaiv zoo heev rau oxidation thiab corrosion, tseem ceeb hauv cov cheeb tsam hnyav.
Hydrogen Attack Resistance: Alloy muaj pes tsawg leeg muaj kev tiv thaiv zoo dua rau hydrogen-induced puas dua carbon steels.
Superior Mechanical Properties (Class 2): Cov txiaj ntsig siab dua thiab lub zog tensile, hardness ntau dua, thiab txhim kho kev ruaj ntseg tom qab kev kho cua sov (normalized & tempered) piv rau Chav Kawm 1.
Txhim khu kev ruaj ntseg & kev ntseeg siab: Muab cov npoo kev nyab xeeb siab dua rau lub sijhawm ntev -, ua haujlwm tsis tu ncua hauv cov xwm txheej hnyav.
Zoo Weldability: tuaj yeem welded zoo rau fabricating complex hlab ntsha Cheebtsam.
Daim ntawv thov
Roj & Gas / Petrochemical Kev Lag Luam
Cov khoom no zoo tagnrho rau cov qaub (hydrogen sulfide) ib puag ncig, siv los tsim hydrotreating/hydrocracking reactors, fractionating kab, gas{0}}kua separators, thiab cia cov hlab ntsha. Nws tiv taus hydrogen sulfide corrosion thiab siab -kub hydrogen nres, tiv taus siab txog 20 MPa thiab kub siab tshaj 400 ° C los tiv thaiv sulfide kev nyuaj siab tawg.
Kev lag luam tsim hluav taws xob
Hauv cov tshuab hluav taws xob thermal, nws yog ib qho tseem ceeb rau lub tshuab boiler: siv rau boiler nruas (steam - dej sib cais nyob rau hauv 540 ° C / 10 MPa), headers (kua faib), thiab siab qhov chaw xws li cov kav dej loj. Nws tiv taus creep deformation, thermal cycling, thiab oxidation los xyuas kom meej system efficiency thiab kev nyab xeeb.
Kev lag luam dav dav
Nws haum rau cov khoom siv hluav taws xob sib txawv, siab -kub txheej txheem piping, thiab welded boilers hla cov tshuaj, tshuaj, thiab metallurgical sectors. Nws muab lub zog muaj zog, zoo heev weldability, thiab kev ua haujlwm ruaj khov nyob rau hauv kev ua haujlwm siab - kub thiab siab - cov kev mob siab rau cov khoom siv tseem ceeb.
