Tool Joints are the enlarged and threaded ends of joints of drill pipe. Hardbanding is a process in which a wear-resistant
Drill pipe tool joints are fabricated separately from the pipe body and welded onto the pipe at a manufacturing facility. The tool joints provide high-strength, high-pressure threaded connections that are sufficiently robust to survive the rigors of drilling and numerous cycles of tightening and loosening at threads. Tool joints are usually made of steel that has been heat treated to a higher strength than the steel of the tube body.
The most cost-effective way to protect tool joints in drilling applications is to hardband them using Duraband® NC. Casing friendly Duraband®NC hardbanding will greatly reduce wear on the OD of the tool joint and can be easily re-applied without removal of existing hardbanding.
