Tubing Rotation Alignment Subs

Need to align your completion?

Flowell’s Tubing Rotation Alignment Sub (RAS) is a quick and easy way to orientate your completion. The RAS is used to assist with the orientation of well completion assemblies within a well completion string. A typical example would be the  orientation between an upper and lower y-tools in dual ESP completions.


The RAS is lockable to left or right hand rotation in 6 degree increments.  The RAS has 30 self meshing clutch teeth that orientate the tubing hanger to the body.  The orientation mechanism requires no power tongs to torque the mechanism into the locked position.  The RAS uses a bidirectional V-stack seals for redundancy to provide a leak proof connection between the production tubing and production casing.  The RAS can be supplied in different tubing sizes, materials, and different elastomeric or non-elastomeric seal materials to meet the customer’s requirements. Where height adjustment is also required, the Flowell Tubing Adjustable Union (TAU) should be used.
