Duraband

Postalloy® Duraband® NC is a 100% crack-free hard band that provides maximum protection of the tool joint and casing. It’s microstructure consists of a hard, but tough tool steel matrix with a high volume of tightly packed micro-constituents. This combination ensures excellent wear resistance in open hole drilling as well as being casing friendly.

Duraband® NC is unique. It is *Fearnley Procter NS-1™ certified for new applications to tool joints and certified for re-application over itself and other hard band products as specified in the NS-1™ re-application approval certificates. It is the only product for maximum protection that is applied crack-free.

Armacor

Nanocrystalline/amorphous alloy coatings are the foundation for Armacor products. They form a structure very different from crystalline alloy coatings used by other similar products. In the amorphous structure, atoms are randomly placed in a continuous coating, preventing corrosion-path grain boundaries. Armacor’s low coefficient of friction amorphous metals:

• Deliver superior wear resistance from abrasive particles in metal-to-metal contact conditions
• Provide excellent non work-hardening machineability and outstanding resistance to cavitation
• Offer improved corrosion resistance to oxidation and sulfidation reactions at elevated temperatures

Arnco

Arnco’s next generation hard banding products were designed to be non-cracking, high performance alloys that cover the spectrum of wear protection needs by end-users. Whether focused on casing wear reduction or drill string life extension, use of Arnco 150XT™ and 350XT™ produce real economic benefits for pipe owners and well operators. Easy initial and re-application combined with alloys designed to resist in-service damage result in reduced re-application costs over the drill pipe life cycle.
