Cov ntawv thov tseem ceeb
Roj & Roj Kev Lag Luam
Cov khoom siv no yog siv dav hauv cov cuab yeej siv hluav taws xob thiab cov kav dej, siv rau cov khoom siv hluav taws xob nyob rau hauv kev kub siab / corrosion, hydrotreating / hydrocracking units rau desulfurization thiab roj kho dua tshiab, siab - kub cia tank rau cov khoom siv roj, thiab cov txheej txheem piping thauj high -kub dej, kom ntseeg tau tias muaj kev nyab xeeb.
Kev lag luam Petrochemical
Nws yog ib qho kev xaiv rau siab - cov khoom siv petrochemical kub, siv nyob rau hauv cov tshuaj reactors rau polymerization thiab alkylation, cia nkoj tuav ethylene thiab propylene, thiab cov txheej txheem cov cuab yeej xws li tshav kub exchangers, withstanding kub, corrosion thiab siab fluctuations.
Kev lag luam tsim hluav taws xob
Rau cov thermal thiab ua ke- voj voog cov nroj tsuag, nws yog irreplaceable rau qhov tseem ceeb siab qhov chaw: boiler drums cais chav thiab dej nyob rau hauv 500℃/ 10 MPa, headers rau cov dej faib, thiab cov kav dej / reheater tubes tiv thaiv thermal qaug zog thiab nkag, kom ntseeg tau lub zog tsim efficiency.
