Mirija ya Boiler ya ASTM A213 T22 isiyo imefumwa

Mirija ya Boiler ya ASTM A213 T22 isiyo imefumwa

T22 Alloy Steel Tube (SA213 T22, Chorme-Moly) ni Tube ya Chuma ya Aloi ya ferritic kwa utawala wa joto la juu. Nyenzo hizi za T22 ikiwa ni pamoja na SA213 T22 Seamless Tube na Alloy Steel T22 Tube zinafaa kwa matumizi ya joto la juu, kwa mfano, kuinama, kupiga (vanstoning), na kazi zinazofanana za kutunga, na kwa kuunganisha mchanganyiko katika biashara ya nguvu na mimea ya petro-compound.
