JIS G 3454Waa heerka warshadaha ee Jabbaan ee tuubooyinka birta kaarboonka ee nidaamyada cadaadiska leh heerkulka ugu badan ee hawlgalka 350°C. Heerkani wuxuu ka kooban yahay laba darajo:STPG 370iyoSTPG 410Waxay khuseysaa tuubooyinka iska caabbinta korontada (ERW) ama tuubooyinka aan kala go 'lahayn ee leh dhexroorka magacaaban ee 10.5 mm ilaa 660.4 mm (tusaale ahaan 6A ilaa 650A, ama 1/8B ilaa 26B).
Tuubooyinka birta ah ee JIS G 3454 waa in la soo saaraa iyadoo la adeegsanayo isku-darka ku habboon ee hababka wax-soo-saarka tuubooyinka birta ah iyo hababka dhammaystirka ee ku jira jadwalka hoose.

Laablaabi karo
Laablaabku wuxuu khuseeyaa tuubooyinka leh dhexroorka magacaaban ee 40 A (48.6) ama ka yar.
Tuubada waa in la qaloociyaa 90° iyadoo dhexroorkeedu yahay 6 jibaar dhexroorkeeda dibadda. Darbiga tuubadu waa inuu ka xor yahay cillado ama dildilaacyo.
Tuubo bir ah kasta waa inay maraan tijaabo cadaadis hydrostatic ah ama tijaabo aan wax burburin ah lahayn.

JIS G 3454 Dulqaadka dhexroorka dibadda, dhumucda derbiga, kala duwanaanshaha, iyo dhererka waa inay buuxiyaan shuruudaha soo socda.
Tan iyo markii la aasaasay 2014, Botop Steel waxay noqotay shirkad hormuud u ah soo-saarista tuubooyinka birta kaarboonka ee Waqooyiga Shiinaha, oo loo yaqaan adeeg heer sare ah, alaab tayo sare leh, iyo xalal dhammaystiran.
Shirkaddu waxay bixisaa noocyo kala duwan oo tuubooyin bir ah oo kaarboon ah iyo alaabooyin la xiriira, oo ay ku jiraan tuubooyin bir ah oo aan kala go 'lahayn, ERW, LSAW, iyo SSAW, iyo sidoo kale saf dhammaystiran oo ah qalabka tuubooyinka iyo flanges.
Alaabteeda gaarka ah waxaa sidoo kale ka mid ah biraha heerka sare ah iyo biraha aan lahayn austenitic, oo loogu talagalay inay daboolaan baahiyaha mashaariicda dhuumaha kala duwan.
Fadlan nala soo xiriir, waxaan ku siin doonnaa tuubooyin bir ah oo tayo sare leh oo heer sare ah oo leh adeeg xirfadeed iyo hufnaan leh. Botop wuxuu rajeynayaa inuu kuu adeego.
