Kulul duuban (tuubo bir ah oo aan kala go 'lahayn): tuubo wareeg ah → kululaynta → daloolin → → rogrogid saddex duuban, rogrogid ama extrusion → goosan → cabbir (ama yaraynta) → qaboojinta → toosinta tijaabada hydraulic (orflaw) → tag → kaydinta.

Tuubada wareegta ee alaabta ceeriin waa tuubo wareegsan, embriyaha tuubada waxay maraan mashiinka wax lagu gooyo si ay u gooyaan kobaca darajada qiyaastii 1 mitir, waxaana soo dira kuleylinta foornada suunka qaada.Billet waxaa lagu quudiyaa foornada kuleylka, heerkulku waa qiyaastii 1200 darajo Celsius.Shidaalka hydrogen ama acetylene.Xakamaynta heerkulka foornada ayaa muhiim ah in la xidho tuubada hawo wareegsan, ka dib marka la sii daayo feerka cadaadiska.kuwaas oo guud ahaan aad uga badan feedh rullaluistemadka feedh this, hufnaan wax soo saarka sare, tayada alaabta, dalool ballaadhin mugga, xidhan noocyo kala duwan oo bir ah.Daloolin ka dib, tuubada wareega ayaa ah saddex duub oo iskutallaab ah oo rogaal celis ah, galgalan ama extrusion.Ka dib marka laga saaro cabbirka tuubada.Mashiinnada lagu cabbiro wareegga xawaaraha sare ee kolayta feerka Billet si loo sameeyo tuubo bir ah.Dhexroorka tuubada birta ee gudaha waxaa lagu go'aamiyaa dhererka dhexroorka dibadda ee daloolista cabbirka.Ka dib markii la qiyaaso, tuubada birta si ay u gasho munaaradda qaboojinta by qaboojinta buufinta biyaha, tuubada birta ka dib qaboojinta, waa lagama maarmaan in la toosiyo.Waxaa loo soo diray tuubo-qaade iyadoo toosinaysa mishiinka ogaanshaha birta (ama tijaabada hydrostatic) si loo sameeyo cillad gudaha ah.Arrimaha gudaha ee dhuumaha birta sida dildilaaca, goobooyinku waa la ogaan doonaa.Kormeerka tayada tuubooyinka birta laakiin sidoo kale iyada oo loo marayo xulashada gacanta ee adag.Dhuumaha birta ee Kormeerka Tayada, Kormeerka, isticmaal rinjiga buufin ee lambarka, cabbirka, dufcada wax soo saarka.By gaadhi fiilo ah oo ka laadlaadsan bakhaarka.
