DURABAND® NC for Maximum Wear Protection In All Drilling Conditions
Case Histories and Field Results
HWDP CWP Hardbanding with Duraband and Tuffband
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.
Water Cooling to Protect the IPC
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.
Sour Gas Service
Tuffband® NC and Duraband NC® are perfectly suited for Sour Gas environments. They are noncracking, 100% rebuildable, casing friendly and NS-1™ approved.
Two Layer Hardbanding with Duraband and Tuffband
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.
Argentina Land Drilling
Duraband goes the distance in Argentina Land Drilling. 39 wells drilled with drill strings totaling 350,000 ft. (108,000 meters).
North Dakota Shale Formation
Duraband ® hardbanded tool joints go 140,000 feet with only 50% wear. Non-hardbanded tool joints lasted only 40,000 feet.
Duraband with Carbide
Canadian land drilling contractor increases tool joint life by over 400% with Duraband® NC plus Tungsten Carbide.
Reapplication Cost Chart
Hardbanding Costs are Dramatically Reduced with Tuffband® NC and Duraband® NC because in many instances the previous hardbanding does not have to be removed!

Center Wear Pad Fatigue Study
Conventional wisdom states that tungsten-carbide mild steel hardbanding is best for center wear pads on drill pipe. Conventional wisdom is wrong.
