Roj & Roj Kev Lag Luam
Nws tuaj yeem siv los tsim cov khoom siv hydrotreating reactors thiab cov khoom tseem ceeb ntawm desulfurization units hauv refineries, tiv taus hydrogen sulfide corrosion thiab siab - ib puag ncig siab thaum lub sij hawm qaub crude roj ua.
Nws kuj tseem tsim nyog rau cov khoom siv roj qaub qaub thiab cov kav xa hluav taws xob hauv kev tshem tawm cov pa roj, nrog rau cov roj cia cov hlab ntsha thiab siab -cov kav dej rau cov roj crude distillation hauv cov txheej txheem qis qis, kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov cuab yeej tseem ceeb thoob plaws tag nrho cov roj thiab roj kev lag luam saw.
Kev lag luam tsim hluav taws xob
Nyob rau hauv thermal fais fab nroj tsuag, nws yog feem ntau siv rau boiler nruas, headers thiab siab -kub boilers kis pipelines, enduring kub tshaj 500℃thiab drastic siab hloov nyob rau hauv lub thermal hwj chim boilers, thiab hloov mus rau cov kev ua hauj lwm ntawm nquag chav tsev startups thiab shutdowns.
Hauv cov chaw tsim hluav taws xob nuclear, nws tuaj yeem siv rau nruab nrab - qhov kub thiab txias ntawm cov khoom siv hluav taws xob, xws li siab- cov qauv kev coj tus kheej cuam tshuam nrog kev sib hloov cua sov hauv nuclear reactor auxiliary systems, lav kev ruaj ntseg ntawm cov khoom siv hluav taws xob nuclear nrog nws cov khoom ruaj khov.
Tsis tas li ntawd, nws muaj feem xyuam rau lub siab tseem ceeb -cov kabmob xws li turbine casings hauv kev sib xyaw ua ke - lub voj voog fais fab nroj tsuag.
Tshuaj Engineering Kev Lag Luam
Nws yog qhov zoo tshaj plaws rau kev tsim cov cuab yeej siv siab -kub corrosive media, xws li cov reactors hauv cov txheej txheem tshuaj lom neeg xws li polymerization thiab alkylation, nrog rau cov kav dej thiab lub tank cia rau thauj cov kua qaub thiab alkali.
Ntxiv mus, nws plays lub luag hauj lwm nyob rau hauv cov khoom tseem ceeb xws li synthesis towers thiab separators nyob rau hauv thee chemical kev lag luam, resisting complex tshuaj tiv thaiv ib puag ncig thiab nruab nrab erosion nyob rau hauv high kub thiab siab siab nyob rau hauv cov thee chemical ntau lawm. Nws kuj tseem tsim nyog rau cov plhaub thiab cov ntawv raj ntawm ntau yam khoom siv hluav taws xob sib txawv hauv cov tshuaj lom neeg.
General Boilers & Heat Exchange Equipment Field
Dhau li ntawm kev lag luam-cov boilers tshwj xeeb, cov khoom siv no tuaj yeem siv rau siab-cov kabmob ntawm ntau lub tshuab boiler lub cev, tiv thaiv thermal qaug zog thiab corrosion tshwm sim los ntawm ntev -lub sij hawm siab - kub combustion.
Hauv hnyav-cov khoom siv hluav taws xob sib pauv hauv kev lag luam xws li tshuaj thiab metallurgy, nws tuaj yeem ua rau hauv cov khoom siv hluav taws xob sib pauv. Kev cia siab rau nws cov cua sov thiab kev tiv thaiv corrosion, nws ua kom cov khoom siv hluav taws xob sib pauv thiab cov khoom siv lub neej hauv kev hloov hluav taws xob thoob plaws hauv kev lag luam sib txawv.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
Puas yog A387 Qib 22 Chav Kawm 1 haum rau kev pabcuam qaub?
Yog lawm. Nws muaj kev tiv thaiv zoo rau hydrogen sulfide corrosion thiab sulfide kev ntxhov siab tawg (SSC), ua rau nws zoo tagnrho rau cov kev pabcuam roj qaub, desulfurization units, thiab lwm yam khoom siv los tuav corrosive qaub hauv kev lag luam roj & roj.
Nws txawv ntawm A387 Qib 22 Chav Kawm 2 li cas?
Chav kawm 1 tau ua kom normalizing + tempering, tsom rau kev ruaj ntseg rau cov pa siab - qhov kub thiab txias. Chav Kawm 2 txais yuav quenching + tempering, nrog lub zog siab dua (lub zog tensile 515-690 MPa) thiab cov kev cai purity nruj dua, haum rau cov xwm txheej hnyav.
