API 5CT Seamless simbi casing uye tubing

Casing Pipe ipombi yakakura-dhayamita iyo inoshanda sechigadziriso chekuchengetedza madziro emafuta negasi matsime, kana tsime. Inopinzwa mugomba uye inosimwa panzvimbo kuitira kudzivirira zvose zviri pasi pevhu uye tsime kuti risadonha uye kuti mvura yekuchera itenderere nekudzurwa kuitika. Simbi Casing Mapaipi ane madziro akatsetseka & mashoma egoho simba re35,000 psi.

API 5CT yakajairwa oiri casing inoita basa rakakosha mukudzivirira mafuta zvakanaka kubva pakukuvadzwa neakadzika mafuta layer uye kutsigira kutakurwa kweoiri negasi. Zvakare, pombi yekasi inogona kutsigira huremu hwemusoro wetsime kudzivirira kudonha. API 5CT casing pombi inogonesa kufambira mberi kwakatsetseka kwese kuchera maitiro, mushure meizvozvo, takura oiri uye gasi kubva pakuchera kusvika pasi.
