ASTM A213 T22, yomwe imadziwikanso kuti ASME SA213 T22, ndi chitoliro chachitsulo chopanda ulusi wochepa chokhala ndi chromium ya 1.90–2.60% ndi molybdenum ya 0.87–1.13% ngati zinthu zazikulu zophatikizira, zomwe zimagwiritsidwa ntchito kwambiri mu ma boiler, ma superheater, ndi ma heat exchanger m'malo otentha kwambiri komanso opanikizika kwambiri.
UNS inati ndi K21590.
Chitsulo cha Botopndi katswiri komanso wodalirika wopereka mapaipi achitsulo cha alloy komanso wogulitsa ku China, wokhoza kupereka mwachangu mapaipi achitsulo cha alloy apamwamba kwambiri pamapulojekiti anu.
Zinthu zonse zimathandiza kuyang'aniridwa ndi anthu ena, ndipo titha kuperekanso zida zofananira za alloy monga zigongono ndi zida zina zapaipi.
Mapaipi achitsulo a T22 ayenera kupangidwa ndinjira yopanda msokondipo iyenera kukhala yotentha kapena yozizira, monga momwe zafotokozedwera.
Mapaipi onse achitsulo a T22 ayenera kutenthedwanso kuti atenthe, zomwe ziyenera kuchitika padera komanso kuwonjezera pa kutentha kuti apange kutentha.
Njira zovomerezeka zochizira kutentha ndi kudzaza kapena kusatentha kwambiri, kapena kusintha kutentha ndi kutentha.
