UREA 25.22.2 tshuaj muaj pes tsawg leeg tau ua kom zoo rau kev siv tshwj xeeb hauv Urea nroj tsuag. Nws yog 310L hloov kho austenitic stainless hlau nrog qis carbon, qis
silicon thiab siab nitrogen ntxiv kom ruaj khov thiab ntxiv dag zog rau theem austenitic. Lub alloy yog tshwj xeeb yog tsim los txhim kho corrosion kuj zog nyob rau hauv urea carbonate ib puag ncig nrog rau strippers. Qib kuj tseem tsim tau zoo rau kev tiv thaiv hauv cov dej ntub dej vim nws cov ntsiab lus siab ntawm chromium, molybdenum thiab nitrogen (PREN> 33). UREA 25.22.2 yog tsim los rau kev tsim cov khoom siv hauv ob sab hauv hauv Urea units lossis cov khoom siv ntxiv (cov kav dej, fittings…). Cov qib yuav siv tau rau urea strippers.

Cov khoom tiv thaiv corrosion yog txhim kho ua tsaug rau qib qis carbon, qib silicon qis thiab ntxiv cov nitrogen ntxiv.
Cov txiaj ntsig siab tshaj plaws corrosion yuav tsum tau ua raws li cov lus qhia sib txawv rau qib 25.22.2 tom qab 5 lub sijhawm ntawm 48 h tom qab ASTM A 262-C xyaum yog:
Qhov siab tshaj plaws corrosion: 1.6 μm / 48 h lossis 65 mg / dm² ib teev nrog qhov siab tshaj plaws ntawm microcracks ntawm 100 μm nyob rau hauv qhov kev taw qhia ntev ntawm dov.
