I-API 5CT i-casing yensimbi engenamthungo kunye ne-tubing

Umbhobho we-Casing Pipe ngumbhobho wobubanzi obukhulu osebenza njengogcino lwesakhiwo kwiindonga zeoyile kunye nerhasi, okanye iqula. Ifakelwa kumngxuma wequla kwaye ifakwe isamente ukuze ikhusele ukumila kobume bomhlaba ongaphantsi komhlaba kunye nequla ekudilikeni kunye nokuvumela ulwelo lokugrumba ukuba lujikeleze kwaye ukutsalwa kwenzeke. Imibhobho yentsimbi yentsimbi inodonga olugudileyo kunye namandla asezantsi esivuno se-35,000 psi.

I-API 5CT i-oyile esemgangathweni ye-oyile idlala indima ebalulekileyo ekuthinteleni i-oyile ukuba yonakaliswe ngumaleko we-oyile ongekho nzulu kunye nokuxhasa ukuthuthwa kwe-oyile kunye negesi. Ngaphezu koko, umbhobho we-casing unokuxhasa ubunzima boluhlu lwe-wellhead ukukhusela ukuwa. Umbhobho we-API 5CT we-casing uqinisekisa inkqubela phambili egudileyo yenkqubo yonke yokugaya, emva koko, ukuthutha ioli kunye negesi ukusuka kwi-drilling ukuya emhlabathini.
