ROSCHEN DS CONNECTIONS


Double Shoulder ab. DS

Roschen has engineered, tested and acquired industry approval for two types of double-shouldered connection.
* The Double Shoulder connection is a generic API double shoulder connection, which is widely used throughout the industry in extended reach drilling.
* The MT connection is an enhanced Double Shoulder connection with additional 25% torsional strength allowing clients to drill the most challenging wells.

PERFORMANCE:

RS-Double Shoulder connection offers higher strength capability than API connections in all aspects

- Up to 40% more torsional strength than API through the high strength secondary make-up shoulder absorbing high frictional load

- Streamlined OD / ID geometry for improved hydraulic performance or fishing ability without compromising torsional capacity

- DPM-DS pin and box connection made up to a smooth ID transition to allow smoother fluid flow with minimized turbulence and energy loss inside the connection. The tendency for mud or cement trap in crevices are eliminated.

- Fully interchangeable with new or used tool joints and accessories with API connections

CHARACTERISTICS:

RS-DS connection is available in drill pipe sizes from OD 2-3/8" to 6-5/8". Other sizes are available upon request. The connection is also available in a wide range of steel grades including sour service and high strength.

Roschen Inc. is constantly striving to improve its products and must therefore, reserve the right to change designs, materials, specifications and price without notice.
