Tuubooyinka birta ah waxay u kala qaybsan yihiin tuubooyinka birta kaarboon ee caadiga ah, tuubooyinka qaab dhismeedka kaarboon oo tayo sare leh, tuubooyinka qaab dhismeedka alloy, tuubooyinka birta daawaha, tuubooyinka birta sidata, tuubooyinka birta aan fiicnayn, tuubooyinka isku dhafan ee bimetallic, tuubooyinka dhejiska iyo dahaarka leh si loo badbaadiyo biraha qaaliga ah oo ay kulmaan shuruudaha gaarka ah..
Marka loo eego habka wax-soo-saarka, waxa loo qaybiyaa laba qaybood: tubooyinka aan xidhnayn iyo tuubooyinka alxanka.Tuubooyinka birta ah ee aan kala go'a lahayn waxaa loo qaybin karaa tuubooyinka kulul, tuubooyinka qaboojiyaha, tuubooyinka qabowga leh iyo tuubooyinka dibadda laga saaro.Tuubooyinka qaboojiyaha iyo qabow-duubka ayaa ah habka labaad ee tuubooyinka birta;Tuubooyinka alxanka leh waxay u qaybsan yihiin tolmo toosan oo alxan leh iyo tuubooyinka alxanka leh.
Marka loo eego qaabka isgoysyada, waxaa loo qaybin karaa tuubo wareegsan iyo tuubo gaar ah.Tuubooyinka qaabka gaarka ah waxaa ka mid ah tuubooyinka leyliga ah, tuubooyinka dheemanka, tuubooyinka elliptical, tuubooyinka laba geesoodka ah, tuubooyinka octagonal, iyo tuubooyinka asymmetrical kala duwan.

Waxaan bixinaa tuubooyinka birta ah ee wareegsan iyo qaabka gaarka ah .
Qalabka , cabbirka waa ikhtiyaari sida waafaqsan baahida macaamiisha.
Sidoo kale waxaanu bixinaa adeega daawaynta dusha sare:
