Tej kev siv
High-siab & Siab-kub Siab Siab Nkoj
Nws yog cov khoom siv zoo tshaj plaws rau kev tsim khoom nruab nrab- mus rau- cov hlab ntsha siab hauv kev lag luam petrochemical, tshuaj, thiab chiv, tshwj xeeb tshaj yog rau cov cuab yeej tuav siab -kub cov tshuaj tiv thaiv, xws li hydrogenation reactors, siab - kub cia tank, thiab synthesis yees.
Advanced Boiler Systems
Siv los tsim cov khoom tseem ceeb ntawm cov boilers thiab fais fab nroj tsuag boilers, nrog rau cov superheater headers, reheater raj, thiab siab -kub cov kav dej, hloov mus rau siab dua thiab kub kev khiav hauj lwm yuav tsum tau ntawm niaj hnub boiler systems.
Roj & Gas Upstream & Cov Khoom Siv Nruab Nrab
Siv nyob rau hauv offshore drilling platforms, subsea ntau lawm systems, thiab onshore high - siab sib sau pipelines, haum rau qaub roj (H₂S- muaj) thiab siab -kub hydrocarbon kua tsheb thauj mus los thiab ua scenarios, nrog zoo zog tiv thaiv corrosion.
Thermal Power & Combined -cycle Fais Fab Cog
Siv los tsim cov khoom siv hluav taws xob rov qab ua kom sov (HRSGs) thiab siab - kub hloov pauv hauv kev sib xyaw ua ke - lub voj voog fais fab nroj tsuag, qhov twg nws tiv taus qhov cuam tshuam ob ntawm siab - kub flue roj thiab siab, txhim kho tag nrho cov txiaj ntsig ntawm lub zog tsim hluav taws xob.
Heavy Chemical Processing Equipment
Txais siv nyob rau hauv cov ntaub so ntswg thiab ntawv mills, kev tsim tshuaj, thiab tsis yog -ferrous hlau smelting industries, rau fabricating siab - kub thiab corrosion- resistant ua khoom xws li digesters, tshav kub exchangers, thiab catalytic reactors.
