Kev lag luam roj thiab roj
Cov khoom siv kho kom zoo: Nws yog dav siv los tsim cov tshuaj hydrotreating reactors thiab cov khoom tseem ceeb ntawm desulfurization units hauv refineries. Thaum ua cov roj crude qaub, cov khoom no tuaj yeem tiv taus corrosion los ntawm hydrogen sulfide thiab siab - siab. Tsis tas li ntawd, nws yog siv rau hauv cov khoom siv roj crude distillation, xws li roj cia cov hlab ntsha thiab siab -cov kav dej, uas lav qhov ruaj khov ntawm cov txheej txheem refining.
Natural gas processing thiab kis tau tus mob: Nws yog qhov tsim nyog rau cov khoom siv roj qaub thaum lub sij hawm tshem tawm roj. Lub caij no, nws tuaj yeem siv los ua cov kav xa dej, tiv thaiv cov roj corrosive thiab kev kub siab hauv cov txheej txheem xa hluav taws xob, thiab ua kom muaj kev nyab xeeb ntawm kev thauj mus los ntawm cov nkev.
Petrochemical thiab Coal Chemical Kev Lag Luam
Petrochemical reactors: Nws yog siv los tsim cov reactors rau polymerization, alkylation thiab lwm yam tshuaj tiv thaiv txheej txheem. Cov reactors no feem ntau ua haujlwm nyob rau hauv siab - kub thiab siab - ib puag ncig siab nrog cov xov xwm corrosive, thiab cov khoom siv corrosion kuj thiab siab - qhov kub thiab txias tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Coal chemical core khoom: Hauv cov thee-rau-syngas thiab thee- rau- cov txheej txheem methanol, nws yog siv los ua cov plhaub ntawm cov roj gasifiers thiab methanol synthesis towers. Cov khoom siv no ntsib qhov kub thiab txias ntawm 400 - 550 degree, siab siab, thiab yaig los ntawm cov xov xwm nyuaj xws li H₂, CO, thiab H₂S. Cov khoom siv tuaj yeem tiv taus corrosion thiab tswj cov qauv kev ruaj ntseg, yog li txhawb nqa lub sijhawm ntev -kev ua haujlwm ntawm cov tshuaj siv hluav taws xob.
Kev lag luam tsim hluav taws xob
Thermal fais fab nroj tsuag: Nws yog cov khoom siv tseem ceeb rau cov khoom siv hluav taws xob thermal boiler, suav nrog boiler nruas, headers, thiab siab -kub qhov hluav taws xob xa hluav taws xob. Cov khoom no yuav tsum tau dais qhov kub siab tshaj 500℃thiab hloov siab heev, thiab kuj hloov mus rau qhov pib nquag- nce thiab kaw cov voj voog ntawm chav nyob. Cov khoom siv tiv thaiv thermal qaug zog thiab creep tuaj yeem ua kom muaj kev nyab xeeb ntawm kev ua haujlwm. Tsis tas li ntawd, nws kuj yog siv rau cov khoom xws li turbine casings nyob rau hauv ua ke - voj voog fais fab nroj tsuag.
Nuclear fais fab nroj tsuag: Nws yog siv rau lub siab ntawm cov hlab ntsha hauv nruab nrab - qhov kub thiab txias ntawm nuclear fais fab nroj tsuag, xws li lub siab -cov kabmob uas muaj feem xyuam rau kev sib pauv cua sov hauv cov koom haum pabcuam ntawm cov tshuab hluav taws xob nuclear. Nws cov khoom siv kho tshuab ruaj khov tuaj yeem txo qhov kev pheej hmoo ntawm cov cuab yeej tsis ua haujlwm thiab ua kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob nuclear.
General Boiler thiab Heat Exchanger FieldTshaj li lub zog thiab tshuaj lom neeg- cov boilers tshwj xeeb, nws yog siv los ua kom siab-cov khoom siv rau ntau yam boilers. Nws tuaj yeem tiv taus thermal qaug zog thiab corrosion tshwm sim los ntawm ntev - lub sij hawm siab - kub combustion. Ntxiv mus, nws yog qhov tsim nyog rau kev tsim cov ntawv raj thiab cov plhaub ntawm cov khoom hnyav-cov khoom siv hluav taws xob hauv ntau qhov kev lag luam. Cov khoom siv hluav taws xob no feem ntau ua haujlwm siab - kub thiab siab - cov kua dej siab, thiab cov khoom siv tuaj yeem ua kom muaj kev sib hloov pauv tau zoo thaum tswj xyuas kev ncaj ncees ntawm cov khoom siv.
