Product Information

• Improved safety & performance Due to higher torque capacity
• Increased torque capacity: Thanks to a second, internal shoulder, the torque distribution throughout the connection is improved.This enables the connection to cope with higher torsional loads.
• Compatible with API connections: DS connections are fully interchangeable with API NC or FH connections. Please see below table for more info. During make-up with standard connections, the internal shoulder of TPS-DS will not get in contact with the back of the API connection. This means that you can still use existing BHA equipment (Please consider that the performance is limited to the properties of the weaker connection in such cases).
• Cost savings: The same equipment as for standard API connections can be used for make-up and running. Shorter make-up times can be realized.
• Increased hydraulic efficiency: The Flush ID of DS connections results in a better hydraulic Efficiency. Additionally, it can be produced with smaller OD/larger ID while still offering the same torsional capacities than standard API connections.
• Extended product lifetime by allowing more OD wear: The DS connection can provide the same torque capacity at a smaller OD compared to standard API Drill Pipe connections. As a result, it can be used longer before being declared as Premium Class or Class II.
