Description

Specialty semi-premium connection machined from API Coupling Stock. The GB CD 3P Connection exceeds pipe body performance properties under all load combinations and is 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.
