Double shoulder provides more than 100% compression, efficiency, high over-torque capacity and enhanced fatigue response.
Proprietary hooked thread profile design provides fully reliable structural capacity under extreme loads and extra fatigue resistance.
High thread taper makes stabbing deeper and easier. The multiple start and low TPI design with self-alignment guides allows fast, trouble-free make-up, requiring only 3/4 of a turn to final make-up. Metal-to-metal seal in sizes up to 22”. Pre-installed elastomeric seal in sizes from 20” to 36”.

The TenarisHydril BlueDock® connector incorporates design concepts from the extensively tested TenarisHydril Blue® Series premium connections and provides reliable performance in the most complex offshore operations. This product has undergone sealability tests based on API RP 5C5 standard and extensive fatigue testing. It has been successfully run by major oil and gas operators working in extremely demanding environments around the world.

The Anti-Rotational Keys (ARK) are field proven, safe and quick to operate, with no need for special installation tools.

The connector is suitable for driving installation.

Tenaris manufactures the pipe and connector under the same quality management system and can supply it as part of a more extensive casing and tubing package for offshore wells.

This solution is backed by Tenaris's global service network providing technical assistance, product testing, pipe management and technical support in the field.
