Sharpe Coarse Flush (SCF) 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.
