Q1: Dab tsi tag nrho cov khoom lag luam yog nyiam rau cov kav roj petrochemical ua kav?
A1: Petrochemical plants commonly use 5Cr-0.5Mo and 9Cr-1Mo-V alloys for their balance of strength and corrosion resistance. Austenitic stainless steels like 304L and 316L handle more corrosive streams. Nickel alloys are specified for severe services involving chlorides or Cov kua qaub {10. Txhua txoj kev xaiv tau raug xaiv raws cov txheej txheem tshwj xeeb thiab cov neeg tuaj yeem ua paug {}}
Q2: Yuav ua li cas ua petrochemical yeeb nkab yuav tsum txawv los ntawm roj thiab roj pipelines?
A2: Petrochemical kav lub ntsej muag ntau dua cov pipelines ua kom muaj kev ntxhov siab ntau dua li cov khoom siv ntub dej {}}} Cov txheej txheem no ua rau ntau dua Xaiv cov kev xaiv tshwj xeeb thiab cov qauv kev sib txuas lus .
Q3: Cov kev sib tw hauv cov kav dej alloy hauv FCC chav nyob?
A3: Cov kua dej catalytic cracking units expose termal freatal-corrasion {}} Cov ntaub ntawv tshwj xeeb}}} Cov ntaub ntawv tshwj xeeb} Ib txwm tuab kho cov kev soj ntsuam yog qhov tseem ceeb kom tiv thaiv kev tsis txaus siab .
Q4: Cov kav dej alloy tau txais kev tiv thaiv cov khoom noj los ntawm cov khoom noj?
A4: Sulfur rov qab cov kav dej yuav tsum tau Alloys Rwb thaiv tsev thiab cov kua txob sab nraud tiv thaiv.} cov kev ntsuas no txuas ntxiv lub neej hauv qhov no Highly corrosive ib puag ncig .
Q5: Dab tsi ua kom muaj kev hloov tshiab tau txhim kho petrochemical yeeb nkab kev ntseeg tau?
A5: Cov kev tsim tawm tshiab muaj xws li corrosion-resistant cluam cov txheej txheem ua kom muaj kev soj ntsuam ntau dua li lub sij hawm tig rov qab {}}
