Drill Pipe Repair

Reconditioning of drill pipe involves full pipe body inspection as per the guidelines of API RP7G, inspection of tool joints and inspection of the critical area covering the weld zone and the internal fade out area from the upset to the pipe body.

The worn out and damaged tool joints are cut off and new tool joints are friction welded to the accepted pipe, machined and post weld heat treated, hardness tested and inspected using wet magnetic particle inspection and ultrasonic methods. The new tool joints can also be provided with hardfacing.

Rethreading of Drill Pipe involves machining of new connection on the damaged tool joint pin and box.

Rethreading of Casing and Tubing involves inspection of the pin threads and the couplings for thread damages. The defective pins are cut off and new pin connections are machined and the damaged couplings are replaced with new couplings. The pipe is hydrostatically tested as per the API Specifications.
