ASME SA-213/ASTM A213 T11 qib seamless yeeb nkab, nominal muaj pes tsawg leeg 1.25Cr-0.5Mo-Si, yog dav siv nyob rau hauv cov qauv ntawm boilers, superheaters thiab tshav kub exchangers.
ASTM A213 T11 seamless kav feem ntau yog siv rau hauv kev tsim cov boilers, superheaters thiab tshav kub exchangers.
Thaum ua haujlwm ntawm qhov kub thiab txias, chav decomposes rau hauv hydrogen thiab oxygen ntawm cov hlau saum npoo, uas yuav ua rau cov pa oxidation ntawm cov hlau mus rau ntau dua li huab cua oxidation ntawm tib qhov kub.
Qhov siab tshaj plaws kev pabcuam kub ntawm T11 qib yeeb nkab yog 565 degree [1050 degree F]. Alloy qib T11 steel yeeb nkab muaj siab oxidation tsis kam, yas thiab thermal zog txawm tias kub txog li 580 degree. Nws muaj kev ua haujlwm zoo welding. Nws yuav tsum tau preheated rau 300 degree ua ntej vuam thiab kev ntxhov siab yuav tsum tau kho tom qab vuam. Nws tau siv dav hauv high-pressure, ultra-high-pressure, subcritical power station boiler superheaters, headers thiab main steam pipes.
