Power Thread Washer

A PTW or Power Thread Washer can be used to clean the thread and seal areas of both the box and pin ends of any API, Premium Connection, and Drill Pipe. Hydrotestors 550 Series, 960 Series, and 1360 Series PTW’s can clean from 3/4″(19.1mm) to 13 5/8”(346.1mm). Most OCTG running procedures require that the tubular connection be cleaned.

The PTW Unit needs a supplied air source of a minimum of 30 CFM at 100 PSI to operate the air motors effectively. The unit also has a 120L tank to hold the cleaning solvent. Once plugged into the supplied air by connecting the Box Head and Pin Head, one trigger activates the air motor to spin the brushes, the second trigger activates the solvent sprayers.

All connections, prior to make–up should be free of all foreign material to ensure proper thread engagement and seal integrity. Therefore reducing costly connection leaks and/or recuts, also extending the life of the threads and seal areas of the box and pin ends. Steel or Nylon Brushes are available for API, Premium connections, or Drill Pipe. A PTW Unit is very versatile as it can be used on the rig floor or at the pipe racks, also minimal training is required to operate the PTW safely. PTW Units are very portable as they will fit into the back of a 1/2 ton pick–up truck for easy transportation.
