A691 91CR Alloy Steel EFW Pipes
A691 91CR alloy steel EFW yeeb nkab feem ntau yog siv rau hauv qhov kub ntawm 482 degree (900 degree F) txog 649 degree (1200 degree F) thiab tuaj yeem tiv taus qhov kub siab dua hauv qee kis. Qhov ntsuas kub no yog txiav txim siab raws li lub zog creep, oxidation tsis kam, thiab corrosion kuj ntawm cov khoom.
A691 91CR welded yeeb nkab muaj qhov dav dua durometer, siab dua qhov thaiv thiab nthuav lub zog. Cov kav dej welded no muaj ntau qhov ntau thiab tsawg los ntawm 1/8 "NB txog 36" NB, 1/4" OD txog 36" OD ntau thiab tsawg.
A691 91CR alloy steel yeeb nkab muaj qhov kub thiab txias thiab corrosion kuj zoo heev. Nws yog dav siv hauv kev lag luam roj thiab roj, kev lag luam tshuaj, thiab kev lag luam fais fab. Hauv cov teb no, nws yog siv los tsim cov cuab yeej tseem ceeb xws li boilers, superheaters, reheaters, thiab xa cov kav dej kom ntseeg tau tias kev ua haujlwm ruaj ntseg ntawm cov khoom siv hauv qhov kub thiab txias.
