ASTM A213 steel raj yog siv dav hauv cov hauv qab no:
1. Petrochemical: Hauv kev lag luam petrochemical, ASTM A213 steel yeeb nkab yog dav siv nyob rau hauv high-temperature thiab high-pressure steam piping systems los muab cov cua sov thiab siab. Piv txwv li, nyob rau hauv cov txheej txheem ntawm cov roj tawg thiab tshuaj lom neeg cov tshuaj tiv thaiv, ASTM A213 steel yeeb nkab tuaj yeem tswj tau qhov kub thiab txias siab kom ntseeg tau tias cov khoom siv tau zoo thiab cov khoom zoo.
2. Fais fab tuag: Hauv kev lag luam fais fab, ASTM A213 steel yeeb nkab yog dav siv hauv chav piping tshuab rau chav turbines thiab thermal fais fab nroj tsuag. Nws tuaj yeem tiv taus qhov kub thiab txias kom ntseeg tau tias lub zog tsim hluav taws xob thiab kev nyab xeeb.
3. Kev tsim kho: Hauv kev tsim kho kev lag luam, ASTM A213 steel yeeb nkab yog dav siv hauv cov cua sov thiab cua txias. Kev siv ASTM A213 steel yeeb nkab muab qhov chaw ruaj khov thiab muaj txiaj ntsig zoo thaum ua kom muaj kev nyab xeeb thiab kav ntev ntawm cov kav dej.
