Product FEATURE
Alloy 690 muaj kev tiv thaiv zoo heev rau intergranular corrosion thiab intergranular kev nyuaj siab corrosion cracking, feem ntau yog siv nyob rau hauv pressurized dej reactor nuclear fais fab nroj tsuag chav generator tshav kub hloov raj cov ntaub ntawv. Pressurized water reactor nuclear power plant steam generator heat transfer tube cov ntaub ntawv tau dhau los ntawm txoj kev txhim kho, suav nrog 304 austenitic stainless hlau, 600 alloy, 800 alloy thiab 690 alloy. Txoj kev tshawb fawb tsis ua haujlwm ntawm 600 alloy hauv kev pabcuam qhia tau hais tias intergranular corrosion thiab intergranular stress corrosion cracking yog cov teeb meem loj. 690 alloy, raws li cov khoom siv rau cov cua kub hloov cov raj ntawm cov tshuab hluav taws xob hauv cov dej siab reactor nuclear fais fab nroj tsuag, tsis tau pom tias tawg txij li thaum nws tau muab tso rau hauv kev siv hauv xyoo 1990.
Daim ntawv thov khoom
Alloy 690 feem ntau yog siv los ua cov khoom siv hluav taws xob hloov hluav taws xob rau cov tshuab hluav taws xob hauv cov dej hauv cov tshuab hluav taws xob hluav taws xob nuclear, uas yog
Lub ntsiab technology ntawm chav generator. Tam sim no, Tuam Tshoj tau ua haujlwm siab zog reactor nuclear fais fab nroj tsuag units, tsuas yog Qinshan kuv siv 800 alloy, Qinshan II, Dada
fais fab nroj tsuag nyob rau hauv Suav teb, tsuas yog thawj theem ntawm Qinshan siv 800 alloy, Qinshan II, Daya Bay thiab Lingao nuclear fais fab nroj tsuag yog siv 690 alloy raws li lub tshav kub hloov tube khoom rau chav generators.
Qinshan II, Daya Bay thiab Ling'ao nuclear fais fab nroj tsuag tau siv 690 alloy ua lub tshuab hluav taws xob hluav taws xob hloov cov khoom siv hluav taws xob.
Feem ntau ntawm cov dej siab reactor nuclear fais fab nroj tsuag nyob rau hauv kev tsim kho thiab kev npaj kuj siv 690 alloy raws li lub tshuab hluav taws xob hluav taws xob hloov hluav taws xob cov khoom siv.
Feem ntau ntawm cov dej siab reactor nuclear fais fab nroj tsuag nyob rau hauv kev tsim kho thiab kev npaj kuj siv 690 alloy li chav generator tshav kub hloov tube khoom.
