SCF® – Sharpe Coarse Flush Casing

SCF® is engineered as fit-for-purpose coarse flush thread for large diameter casing suitable for surface, intermediate, production, GOAF wells and liners. SCF® allows easy stabbing and time efficient rig make-up. SCF® is integrally threaded at each end of the pipe body with a fully flush internal and external metal to metal seal.
