All drill pipe and tool joints are manufactured in our modern and technologically advanced manufacturing facility at USI . Each tool joint is forged, machined, processed, inspected and tested by qualified operators to ensure the quality meets or exceed API specifications and customer’s requirements.

drill_pipe3The Pipe Body and Tool Joint are joined together by friction welding.  Each heat affected zone is quenched and tempered using our post weld heat treatment system to ensure a strong, tough and uniform weld zone.

100% of all friction welds are inspected by UT & MPI and hardness readings are taken across the heat affected zone.   The friction weld area both internal and external are ground and sanded to a smooth finish to ensure these critical areas are free of stress risers.
