Dhuumaha Casing waa tuubo dhexroor weyn oo u adeegta sidii haynta qaab dhismeedka derbiyada ceelasha saliidda iyo gaaska, ama ceelka dhuuban. Waxa la geliya ceel biyood oo sibidh lagu shubo si ay uga ilaaliso in ay samaysmaan dhulka hoostiisa iyo ceelka ceelasha in ay soo dumaan iyo in dareere qodiddu uu wareego oo soo saaro. Tuubooyinka Dabooska birta waxay leeyihiin darbi siman & xoogga wax soo saarka ugu yar ee 35,000 psi.
Daboolka saliida ee API 5CT wuxuu door muhiim ah ka ciyaaraa kahortagga si fiican saliida inuu waxyeeleeyo lakabka saliida gacmeed iyo taageerida gaadiidka saliida iyo gaaska. Intaa waxaa dheer, tuubada daboolku waxay taageeri kartaa miisaanka lakabka ceelka si looga hortago burburka. API 5CT tuubbooyinka daaska ayaa hubiya habsami u socodka hawsha qodista oo dhan, intaas ka dib, saliidda iyo gaasta ka soo qaada qodista ilaa dhulka.
