Wedge Thread Drill Pipe Tool Joint

With more than 40,000 joints in service Wedge Thread tool joints are becoming recognized as the industry leader in the most demanding environments. The patented Wedge Thread design allows the connection to seal on the flanks of the threads, instead of on the shoulder like conventional tool joints. Since the torque is absorbed by the flanks of the threads, a smaller OD/ID ratio can be used for improved hydraulic efficiency- while providing superior torque strength. The Wedge Thread design also provides the operator with a rugged, durable connection capable of superior performance in field repairability- which eliminates the need for expensive re-cuts.
