Steelfabs rotating centralizers can be used with a rotating liner in highly deviated well conditions.
The centralizers have high restoring force which provides optimum standoff and low moving force to minimize drag. They meet or exceed API 10D specifications.
The centralizers allow free rotation of the pipe for maximum displacement efficiency. The stop collar between the end collars minimises moving forces while reciprocating. The sizes available are 4½" x 6" and 7" x 8½".
