Flush OD connection facilitates running and circulating and eliminates down hole coupling face hang-up.

Exceptional torque strength developed through the simultaneous engagement of opposing flanks of the dovetail thread, permitting rotating and wash over in deviated holes without fear of structural failure.

Stabbing resistance of the pin end face is maintained with the swaged, stress relieved and machined ID to receive a standard drift.

Features

High compression rating provided by the reverse angle stab flank of the dovetail threads makes the Wedge 511™ suitable for use as slotted liners in geothermal and stream injection service. Compression strength exceeds tension strength.
100% pipe body collapse strength created with the lubricant seal of the dovetail threads.
