Best in class : compatibility
Very Good wear performance.
Hardness : 55 to 57 Rockwell “C” Scale.
API® Standard 7CW Casing Wear Tests :
- Casing Wear Factor : 0.94 x 10-10 psi-1
- Frictional Factor : 0.36 dimensionless
- Hardband OD Loss : 0.009 in
- Tool Joint Weight Loss : 0.070 lbs
Can also be applied with tungsten carbide for the enhanced protection of BHA components.
Historically, hardbanding wires that exhibited improved tool joint protection did not have very good compatibility with other hardbanding wires. The DRILL-GUARD series offers superior protection and includes hardbanding wires with excellent welder appeal and a high level of compatibility with competitive hardbanding products.
An inspection of the previous worn hardbands and if required the approved repair(s) prior to re-application of hardbanding is inherently part of the hardbanding process.
