Fearnley Procter NS-1™ allows the use of only non-cracking hardbanding on Center Wear Pads. Therefore Duraband®NC or Tuffband®NC are acceptable for initial application and re-application.
Protecting the internal plastic coating (IPC) in drill pipe from burning or scorching during the hardbanding process can be done with the water cooling. If not properly done, hardness in the heat affected zone (HAZ) could rise to unacceptable levels.
Tuffband® NC and Duraband NC® are perfectly suited for Sour Gas environments. They are noncracking, 100% rebuildable, casing friendly and NS-1™ approved.
Both Duraband® NC and Tuffband® NC can easily accommodate double layer deposits. It is important to understand that the two layers must be applied in succession.
Hardbanding Costs are Dramatically Reduced with Tuffband® NC and Duraband® NC because in many instances the previous hardbanding does not have to be removed!
