Petrochemical kev lag luam

Daim ntawv thov teb ntawm cov alloys tshwj xeeb hauv kev lag luam roj av:

Petroleum kev tshawb nrhiav thiab kev loj hlob yog ntau txoj kev qhuab qhia, kev siv technology-intensive thiab peev-intensive kev lag luam uas yuav tsum tau siv ib tug loj tus naj npawb ntawm metallurgical cov ntaub ntawv thiab cov khoom uas sib txawv zog thiab siv. Nrog rau txoj kev loj hlob ntawm ultra-dav thiab ultra-inclined roj thiab roj qhov dej thiab cov roj thiab roj av uas muaj H2S, CO2 thiab Cl -, daim ntawv thov ntawm stainless hlau cov ntaub ntawv nrog rau kev tiv thaiv corrosion yuav tsum tau nce.

Txoj kev loj hlob ntawm kev lag luam petrochemical thiab kev rov ua dua tshiab ntawm cov cuab yeej petrochemical tau muab cov kev xav tau siab dua rau kev ua tau zoo thiab kev ua haujlwm ntawm stainless hlau. Cov kev cai rau kev tiv thaiv corrosion, kub tsis kam thiab kub tsis kam ntawm stainless hlau tsis so tab sis nruj dua. Nyob rau tib lub sijhawm, kev lag luam petrochemical kuj tseem muaj qhov kub thiab txias, kev kub siab thiab kev lag luam tshuaj lom, uas txawv ntawm lwm cov kev lag luam. Qhov tshwm sim ntawm kev sib xyaw cov ntaub ntawv tsis pom tseeb. Thaum qhov zoo ntawm stainless hlau cov ntaub ntawv nyob rau hauv kev lag luam petrochemical tsis tuaj yeem lav tau, cov txiaj ntsig yuav yog qhov tsis txaus ntseeg, yog li ntawd, cov tuam txhab stainless hlau hauv tsev, tshwj xeeb tshaj yog cov tuam txhab steel yeeb nkab, yuav tsum txhim kho cov ntsiab lus thiab cov nqi ntxiv ntawm cov khoom kom sai li sai tau los tuav lub high-end khoom lag luam.

Feem ntau siv nyob rau hauv reactors nyob rau hauv petrochemical khoom, roj zoo raj, polished rods nyob rau hauv corrosive roj qhov dej, kauv raj nyob rau hauv petrochemical furnaces, thiab qhov chaw thiab cov khoom ntawm cov roj thiab roj drilling khoom.
