Severe Wear Drilling can Benefit from Guardian Hardband

The NanoSteel Company’s Guardian HB is the first engineered tool joint hardband. When initially introduced it was the first casing-friendly hardbanding material which also shielded drill pipe tool joints. The Guardian HB has been proved on over 1,000 miles of drill pipe and still remains a favorite high-performance workhorse among drilling contractors, oil companies, and hardbanding applicators.

Performance of the Guardian HB

The versatility of the Guardian HB ensures its performance in severe wear drilling environments. NanoSteel’s patented nanotechnology provides the Guardian HB the necessary toughness and impact resistance for resisting spalling and flaking downhole. More than 700 miles of drill pipe has been supplied to customers over the past five years. The Guardian HB is the perfect choice for drill pipe proprietors and oil companies, as they can choose from a wide range of original and after market applications.

When compared with traditional hardband materials, the Guardian HB does not substitute either hardness or toughness to realize its special properties. Dye penetrant testing enables customers to see how NanoSteel’s patented nanotechnology enhances the Guardian HB to provide long service life and highly efficient tool joint performance.

Salient Features of the Guardian HB

The salient features of the Guardian HB are:

  • Better tool joint protection in casing – The Guardian HB provides improved tool joint life than most casing friendly hardband material, this can be seen by the 37% reduction in case wear in comparison with the next best performer when subjected to the DEA 42 wear test. The reason for the successful casing and tool joint wear protection is its nano-sized metallurgical grain structure.

  • Easy reapplication – The special properties of the Guardian HB enables very easy reliable and quick reapplication by field service welding teams. This results in fast turnarounds in the field, and saves substantial cost over the service life of the drill pipe.
  • Crack free through matched expansion- Residual stresses and cracking are much lesser in the Guardian HB as it is designed with a thermal expansion co-efficient, which is similar to that of the base tool joint steel, thus increasing performance and the service life.
