ULTRA™ DQX
The proprietary ULTRA™ thread design reduces hoop stresses on the coupling and provides adequate torque capacity for shales applications.
The proprietary ULTRA™ thread design reduces hoop stresses on the coupling and provides adequate torque capacity for shales applications.
Provide high tension and compression efficiency, and even stress distribution.
Pin-to-pin back-up mechanism provides high torque capacity and compression ratings.
Low interference run-out threads enhance fatigue life and maximize critical cross-sectional area.
Featuring the patented ULTRA™ thread form with a pin-to-pin torque stop, this cost-efficient connection provides better performance than an API Buttress-compatible: improved sealability, galling resistance, lower running time. Supported by over 80 million feet of successful run history in major US shale plays.
TenarisHydril Wedge Series connections provide exceptional torque performance and are recognized as the most robust and fastest running connections in the market.
