API 5CT chiyero pane mafuta casing neAmerican Petroleum Institute, kunyanya kune pombi yemafuta, tubing uye casing.

API 5CT oiri casing inoshandiswa mukuchera matsime emafuta, ayo anonyanya kushandiswa kuchera uye kupedzisa kwerudyi rusvingo rwerutsigiro, kuve nechokwadi chekuti mufambiro uye kupedzwa kwekuchera mushure mekushanda kwemaitiro ematsime.Casing ndeyekuchengetedza matsime ekufambisa nzira yehupenyu.Sezvakasiyana geological mamiriro, pasi pevhu yakaoma kushushikana mamiriro, kudhonza, kudzvanya, kukotama, torsional kushushikana kunobata pane yakasanganiswa mhedzisiro yechubhu, iyo iyo casing pachayo, kunaka kwepamusoro zvinodiwa.Kana iyo casing pachayo yakuvadzwa nekuda kwechimwe chikonzero, inogona kutungamira kumatsime ekugadzira ese, kana kutoputswa.
