Cov ntawv thov tseem ceeb
Roj & Roj Kev Lag Luam
Cov khoom siv no yog ib qho kev daws teeb meem tseem ceeb rau cov hlab ntsha siab, hnyav -cov kav dej ua haujlwm, thiab cov kua dej- tuav cov cuab yeej tshwj xeeb rau kev khaws cia thiab kev thauj mus los ntawm cov roj, roj, thiab lwm yam dej hauv qab qhov kub thiab txias. Nws yog tsim tshwj xeeb los tiv thaiv cov kev ua haujlwm hnyav uas muaj nyob rau hauv kev tshawb nrhiav dej ntws, midstream kis tau tus mob, thiab nqes dej ua kom zoo dua ntu, kom ntseeg tau ntev - lub sij hawm kev ncaj ncees thiab kev ntseeg siab txawm tias thaum raug kev hloov pauv siab loads thiab corrosive media inherent nyob rau hauv cov roj thiab roj nqi saw.
Petrochemical & Kev Lag Luam Kev Lag Luam
Nws yog dav siv nyob rau hauv kev tsim cov txheej txheem cov cuab yeej tseem ceeb, suav nrog cov reactors, plhaub - thiab - raj cua kub exchangers, thiab cov hlab ntim khoom siv nyob rau hauv kev xav tau tshuaj ib puag ncig. Cov ntawv thov no feem ntau cuam tshuam nrog cov khoom hnyav xws li cov kua qaub muaj zog, alkalis, cov kuab tshuaj organic, thiab siab - cov tshuaj tiv thaiv kub. Cov khoom siv tshuaj lom neeg muaj zog thiab kev ua haujlwm ruaj khov ua rau nws zoo tagnrho rau kev ua haujlwm tas mus li hauv cov nroj tsuag petrochemical, cov chaw tsim tshuaj tshwj xeeb, thiab cov kab ntau lawm uas cov cuab yeej ua haujlwm ncaj qha cuam tshuam cov txheej txheem kev ua haujlwm thiab kev nyab xeeb.
Kev lag luam tsim hluav taws xob
Cov khoom siv yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov khoom tseem ceeb ntawm lub tshuab tsim hluav taws xob, xws li boiler siab qhov chaw (xws li boiler raj, headers, thiab nruas) thiab cov cuab yeej pabcuam ua haujlwm nyob rau hauv siab heev - kub thiab siab - siab. Nws yog dav siv nyob rau hauv thermal fais fab nroj tsuag, nuclear fais fab auxiliary systems, thiab concentrated solar power (CSP) chaw, qhov twg nws tiv thaiv thermal qaug zog, creep deformation, thiab oxidation - yam tseem ceeb rau kev tswj cov efficiency thiab ntev ntawm lub zog tsim infrastructure.
Fabrication Sector rau Cov Khoom Siv Siab
Nws yog cov khoom siv tseem ceeb rau kev tsim cov welded boilers, compact heat exchangers, thiab siab hlab ntsha uas tswj cov neeg kho tshuab muaj zog, tshwj xeeb siab - kub creep kuj, thiab superior oxidation kuj. Fabricators cia siab rau nws cov weldability thiab seem stability los tsim cov khoom uas ua raws li cov qauv kev lag luam nruj (xws li ASTM, ASME, EN). Cov khoom siv no tshwj xeeb tshaj yog tsim rau kev cai- ua kom siab- cov kabmob uas siv hauv kev lag luam uas cov khoom siv ua haujlwm dhau qhov kev txwv ntawm cov pa roj carbon steels, ua kom muaj kev nyab xeeb thiab kev tswj xyuas zoo.
