Dhuumaha birta ee derbiga culus waa nooc ka mid ah tuubooyinka dhumucdiisuna ay ka sarreeyaan celceliska.Habka wax-soo-saarka ee birta darbiga culus ee tuubbada aan xuduudda lahayn waxaa loo qaybin karaa afar hab oo aasaasi ah: qabow la jiido, qabow duuban, kulul duuban, iyo balaadhin kulul.Marka loo eego ujeedada, waxaa loo qaybin karaa tuubo bir ah oo aan lahayn qaab dhismeedka;Dhuumaha birta ah ee aan xidhnayn ee gaadiidka dareeraha ah;tuubo bir ah oo cadaadis-sare leh oo kululeeyaha;tuubo bir ah oo cadaadis sare leh oo loogu talagalay qalabka bacriminta;Dhuumaha birta ah ee aan xuduud lahayn ee qodista juqraafiga;Dhuumaha birta ah ee qodista saliidda;Dhuumaha birta ah ee aan kala go 'lahayn ee saliidda dillaacsan;Dhuumaha birta ah ee aan xuduudda lahayn ee dhismaha maraakiibta;tuubooyinka daawaha kala duwan.Tuubooyinka birta ah ee aan waxba tarayn waxaa lagu muujiyaa dhexroorka dibadda iyo dhumucda derbiga.

Habka wax soo saarka

Tuubada wareegta ah → kululaynta → daloolin → rogo rogaal celis ah, rogrogid joogto ah ama extrusion → xariijimo → cabirida (ama yaraynta dhexroorka) → qaboojinta → toosinta → tijaabada hydraulic (ama ogaanshaha cilladaha) → calaamadaynta → bakhaarka.

Goobta Codsiga

Dhuumaha birta ah ee derbiga culus ee aan sinaba lahayn ayaa inta badan loo isticmaalaa ilaalinta biyaha, kiimikaad kiimikaad, kiimikaad, koronto, waraabka beeraha, dhismaha magaalooyinka iyo warshadaha kale.Gaadiidka dareeraha ah: sahayda biyaha iyo qulqulka.Gaadiidka gaaska: gaaska dabiiciga ah, uumiga, gaaska dareeraha ah.Isticmaalka qaabdhismeedka: loo isticmaalo sidii buundada tuubooyinka tuubooyinka;dekedaha, waddooyinka, dhismayaal iyo dhismayaal kale.
