API 5CT K55 Casing Thiab Tubing Pipe yog dab tsi?
K55 Roj Tubing yog siv rau hauvroj qhov dej drilling, ua raws li American Petroleum Institute (API) tus qauv 5CT, thiab koom nrog qib K-55 hauv kev faib cov hlau casing. Cov khoom no tuaj yeem muab cov xov thiab txuas txuas, thiab tseem tuaj yeem muab nrog cov xaus, cov xov puag ncig, cov xov trapezoidal, thiab cov xov tshwj xeeb. Lub teb chaws tuaj txawv teb chaws suav nrog lub teb chaws Yelemees, Nyiv, thiab Romania, thiab cov khoom raug xa tawm mus rau Russia, Nyiv, Australia, thiab ntau lub teb chaws thiab cheeb tsam. Cov qauv siv suav nrog API 5A, 5AX, thiab 5AC, thiab qib steel npog H40, J55, K55, N80, L80, C90, T95, P110, Q125, thiab V150.
