GB/T5310-2008Tuubbada birta ah ee bilaa-xun waa nooc ka mid ah tuubo bir ah oo tayo sare leh.Tuubada kuleyliyaha waxay u qaybsantaa tuubada kuleyliyaha guud iyo tuubada kuleyliyaha cadaadiska sare iyadoo loo eegayo heerkulkeeda sareeyo.Tuubooyinka kuleyliyaha cadaadiska sare waxaa inta badan loo isticmaalaa soo saarista cadaadis sare iyo cadaadiska ka sareeya kuleyliyeyaasha uumiga, tuubooyinka iyo birta qaab dhismeedka kaarboon tayadoodu sareyso, birta qaab dhismeedka alloy iyo kulaylka aan fiicnayn ee birta u adkeysanaysa birta birta ah ee aan fiicnayn.[1] Tuubooyinkan kuleyliyaha ah waxay ku shaqeeyaan heerkul sare iyo cadaadis, soo saara gaaska qiiqa heerkulka sarreeya iyo uumiga biyaha, kuwaas oo u nugul oxidation iyo daxalka.

Heerka birta

(1) Bir qaab dhismeedka kaarboon tayo sare leh 20G, 20MnG, 25MnG. 

(2) Qaab dhismeedka Alloy steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, iwm. 

(3) Birta kulaylka u adkeysata daxalka oo caadi ahaan loo isticmaalo 1Cr18Ni9, 1Cr18Ni11Nb tuubada kuleyliyaha marka lagu daro si loo hubiyo ka kooban kiimikada iyo sifooyinka farsamada, si loo sameeyo tijaabada cadaadiska biyaha, si loo sameeyo flaring, tijaabin cadaadis.Tuubooyinka birta waxaa lagu keenaa xaalad daawaynta kulaylka. 

Intaa waxaa dheer, qaab-dhismeedka yaryar, cabbirka hadhuudhka iyo lakabka decarburization ee tuubooyinka birta ee la dhammeeyey ayaa sidoo kale loo baahan yahay.
