Daim ntawv thov

Roj & Roj Kev Lag Luam: Refineries, petrochemical nroj tsuag, cov kev pabcuam roj qaub, thiab siab - cov kav dej kub uas tiv taus hydrogen sulfide corrosion, siab siab, thiab cyclic thermal stress nyob rau hauv ib puag ncig ua haujlwm hnyav-zoo tagnrho rau kev rho tawm cov dej ntws, kev thauj mus los hauv nruab nrab, thiab cov dej hauv qab ua kom zoo rau cov kua qaub thiab cov roj sib xyaw ua ke.

Lub zog tiam: Boiler nruas, headers, thiab siab -kub chav piping nyob rau hauv thermal thiab ua ke - voj voog fais fab nroj tsuag, ua kom ntev - lub sij hawm kev ruaj ntseg nyob rau hauv lub siab heev thiab kub loads, txawm thaum lub sij hawm nquag pib- kaw lub voj voog thiab txuas ntxiv siab -kub 40 degree.

Kev ua tshuaj lom neeg: Cov khoom siv hauv cov chaw tuav cov dej kub corrosive thiab gases, yoog mus tas li siab -kub cov tshuaj tiv thaiv kab mob thiab cov tshuaj lom neeg muaj zog xws li acids, alkalis, thiab cov kuab tshuaj organic siv hauv polymerization, alkylation, thiab oxidation txheej txheem.

Kub Exchangers & Boilers: Cov khoom tseem ceeb uas yuav tsum tau ua kom ntseeg tau los tiv thaiv tshav kub thiab corrosion, haum rau hnyav -lub luag haujlwm thermal hloov tshuab thoob plaws ntau yam kev lag luam suav nrog kev siv tshuaj, metallurgy, thiab kev ua zaub mov, qhov tseem ceeb thiab kev nyab xeeb.
