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
