Tuubooyinka qodista ayaa si weyn loogu isticmaalaa macdanta, sahaminta juqraafiyeed iyo dhammaan noocyada qodista (biyaha, saliidda, gaaska, iwm) mashaariicda. Sida wax soo saarka tuubooyinka daloolin hormuudka ah, waxaan ka dhigi dhammaan noocyada kala duwan ee heerarka iyo tuubooyinka aan caadiga ahayn ee macaamiisheena.Tuubooyinka daloolkeena oo ay ku jiraan birta daloolista, tuubada qodista macdanta, tuubada ceelka ceelasha biyaha, tuubada ceelka saliidda, tuubada daloolista API, Usha daloolista DTH, usha daloolista fiilada, iwm.

Astaamaha ugu muhiimsan ee tuubada DTH ee tayada sare leh waa adkeysiga, saxnaanta iyo maaraynta.

 Dhuumaha qodista :

1.Pipe body: qabow jiid tuubo aan kala go' lahayn.sidaas darteed tuubooyinku waxay leeyihiin cabbirka saxda ah, xarun dhexe oo wanaagsan.
2.Waxyaabaha jidhka ka samaysan ee tuubbadu waxay la mid yihiin heerka Sandvik.
3.Thread Connector :Heat and Nitrogen treatment , si ay beebku u waarto una fududaato in la raro .
4.Alxanka is jiid jiidka .

Tuubbada daloolista caadiga ah ee DTH:

Dhexroorka: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm;
