Field-approved semi-flush

An integral semi-flush connection suitable for a range of functional applications from large-diameter surface casing to extended reach strings and drilling liners, where high clearance is required. Wedge™ Series 500 is field-proven by more than 30 years of history, becoming a standard in many operations. Reliability and high performance are its main features. Special applications include drilling with casing, slotted liners for geothermal wells and rotation-while-bending during wash-down and cementing.
