Waa maxay qalabka ugu muhiimsan ee tuubooyinka kuleyliyaha birta daawaynta cadaadiska sare?

Tuubbada Alloy waa nooc ka mid ah tuubooyinka birta ah ee aan fiicnayn, laakiin heerkulkeeda sare, iska caabbinta heerkulka hooseeya, iska caabbinta daxalka ayaa ka sarreeya tuubada birta ah ee celceliska ah, sababtoo ah waxay ka kooban tahay Cr badan, sidaas darteed tuubada alloy ee saliidda, Korontada, kuleyliyeyaasha iyo kuwa kale. warshadaha waxay leeyihiin tiro balaadhan oo ah codsiyada.

Waxaa guud ahaan loo isticmaalaa kuleyliyaha cadaadiska hooseeya ama dhexdhexaadka ah (cadaadiska shaqada ≦ 5.88mpa, heerkulka shaqada ≦ 450 ℃) ee tuubada dusha kululaynta;loogu talagalay kuleyliyaha cadaadiska sare (cadaadiska shaqada ≧ 9.8mpa, heerkulka hawlgalka u dhexeeya 450 ℃-650 ℃) ee tuubada dusha kululaynta, gobolka Dhuxul, superheater, reheater, petrochemical tube warshadaha petrochemical.
