Guardian HB is the first tool joint hardband to provide minimum casing wear while providing excellent tool joint protection.
- Industry leading casing wear protection
- High tool joint protection in casing
- Very easily reapplied over itself
- Superior spalling resistance
PROVEN IN SEVERE WEAR DRILLING ENVIRONMENTS
Guardian HB easily resists wear in harsh environments encountered in reach, deepwater, and abrasive hard rock drilling, making it the ideal choice of oil companies and drill pipe owners for tool joint protection.
SUPERIOR CRACKING RESISTANCE
Guardian HB has been engineered to contract and expand at the same rate as the tool joint steel to resist cracking during shop and field applications. Matching the coefficient of thermal expansion (CTE) of the hardband material and base tool joint steel enables higher strength and hardness without detrimental cracking tendencies. Conventional hardbands have traditionally lowered their strength and hardness to reduce cracking, which consequently sacrifices tool joint protection performance.
INDUSTRY LEADING CASING & TOOL JOINT WEAR PROTECTION
The near-nanoscale grains in the microstructure of Guardian HB deliver the industry’s absolute best casing protection.In DEA 42 tests, Guardian HB shows a 37% reduction in casing wear over the nearest “casing friendly” competitor.Guardian HB not only minimizes casing wear, it provides significantly better tool joint protection in casing than any other “casing friendly” hardband product.In DEA 42 tests, Guardian HB shows a 55% improvement in radial tool joint wear resistance in casing compared to the second best performer.
