DPM – DS

DP-Master has engineered, tested and acquired industry approval for two types of double-shouldered connection.
The DS 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 DS connection with additional 25% torsional strength allowing clients to drill the most challenging wells.

- 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

DPM-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.
