API 5CT Chophimba chachitsulo chosasunthika ndi machubu

Casing Pipe ndi chitoliro cham'mimba mwake chachikulu chomwe chimagwira ntchito ngati chosungira pamakoma a zitsime zamafuta ndi gasi, kapena zobowoleredwa bwino. Amayikidwa m'chitsime ndikumangiriridwa ndi simenti kuti ateteze mapangidwe apansi pa nthaka ndi chitsime kuti chisagwe komanso kulola kuti madzi obowola azizungulira ndikuchotsa kuti kuchitike. Mapaipi Oyika Zitsulo ali ndi khoma losalala & mphamvu zokolola zochepa za 35,000 psi.

API 5CT mulingo wamafuta wamba umakhala ndi gawo lofunikira poteteza chitsime chamafuta kuti zisawonongeke ndi wosanjikiza wamafuta osaya komanso kuthandizira mayendedwe amafuta ndi gasi. Kuonjezera apo, chitoliro chachitsulo chikhoza kuthandizira kulemera kwa chitsime cha chitsime kuti chiteteze kugwa. API 5CT casing pipe imaonetsetsa kuti ntchito yonse yobowola ikuyenda bwino, pambuyo pake, kunyamula mafuta ndi gasi kuchokera pakubowola mpaka pansi.
