Drill rod TPS-DS

Double Shoulder Drill Pipe Connection Double Shoulder Connections Double Shoulder Connections are particularly suited for difficult operations, such as extended and deep drilling, horizontal and slim hole wells. TPS-DS (Double Shoulder) offers many advantages compared to Standard API Drill Pipe connections. Key facts and advantages: Fully interchangeable with API NC or FH connections Increased torque capacity and hydraulic efficiency Extended product life time Due to higher 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. TPS-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). The same equipment as for standard API connections can be used for make-up and running. Shorter make-up times can be realized. The Flush ID of TPS-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.
