Description

Specialty semi-premium connection machined from API Coupling Stock. Like the GB CD 3P, both the GB WS 3P and GB HB 3P Connections exceed pipe body performance properties under all load combinations and are gas tight. Connection designed with 3-Pitch threadform for easy-stabbing, fast makeup without cross-threading. Innovative, triple taper thread design (box only) reduces localized bearing stresses in critical areas for improved fatigue resistance. Pin noses meet in the center for positive indication of proper field makeup. Pin noses, designed for maximum bearing face area, provide high torque resistance.

GB WS 3P has integral, sacrificial wear sleeve to protect the leading edge and critical areas of the connection that commonly wear during drilling operations. For the most abrasive environments the wear sleeve can be furnished with hard-facing (GB HB 3P).
