JIS G 3454waa heerka warshadaha Japan ee tuubooyinka birta kaarboon ee nidaamyada cadaadiska leh heerkulka ugu sarreeya ee 350 ° C.Heerku wuxuu ka kooban yahay laba darajo:STPG 370iyoSTPG 410.Waxay khusaysaa iska caabbinta korantada ee alxanka (ERW) ama tuubooyinka aan sinaba lahayn ee leh dhexroor magaceedu yahay 10.5 mm ilaa 660.4 mm (ie 6A to 650A, or 1/8B to 26B).
JIS G 3454 Tuubooyinka birta ah waa in lagu soo saaraa iyadoo la adeegsanayo isku dhafka habboon ee hababka wax soo saarka birta iyo hababka dhamaystirka shaxda hoose.

Tijaabada fidsan
Marka masaafada u dhexeysa labada taarikada ay gaarto masaafada la cayimay H, waa in aysan jirin cillado ama dildilaaca dusha sare ee tuubada birta.
Tuubooyinka birta ah: H = (1+e) t/(e + t/D);

JIS G 3454 U-dulqaadashada dhexroorka dibadda, dhumucda gidaarka, sinnaanta, iyo dhererka waa inay buuxiyaan shuruudaha soo socda.
Tan iyo markii la aasaasay 2014, Botop Steel waxay noqotay shirkad hormuud ka ah tuubooyinka birta kaarboon ee Waqooyiga Shiinaha, oo loo yaqaan adeeg aad u wanaagsan, alaab tayo sare leh, iyo xalal dhammaystiran.
Shirkaddu waxay bixisaa noocyo kala duwan oo ah tuubooyinka birta kaarboonka iyo alaabada la xidhiidha, oo ay ku jiraan kuwa aan fiicneyn, ERW, LSAW, iyo tuubada birta ee SSAW, iyo sidoo kale saf buuxa oo ah xirmooyinka tuubooyinka iyo flanges.
Alaabooyinkeeda gaarka ah waxa kale oo ka mid ah alloys-ga sare iyo biraha austenitic ahama, oo loogu talagalay in lagu daboolo baahiyaha mashaariicda dhuumaha ee kala duwan.
Fadlan nala soo xiriir, waxaan ku siin doonaa tayo sare leh, tuubooyinka birta caadiga ah oo leh adeeg xirfad leh oo hufan.Botop wuxuu rajeynayaa inuu kuu adeego.
