Wear resistant hardbanding alloys for the worldwide petroleum industry

Hardbanding Basics

Hardbanding is the process of depositing hardfacing alloys onto drill pipe tool joints, collars, heavy weight drill pipe and other down hole components to protect both casing and drill string assets from abrasive wear. Hardbanding is most commonly applied to the box end of drill pipe tool joints using a MIG welding process, bonding the hardbanding alloy with the parent steel of the drill pipe.  There are, however, other hardbanding application methods that are occasionally used including laser and plasma arc processes. 

The need for hardbanding arose decades ago when drilling contractors and operators wanted a way to protect casing and extend the life of costly drill string equipment from wear associated with rotational and axial forces while drilling and tripping in and out of a well. Initially, tungsten-carbide particles were dropped into a mild-steel matrix, remaining the industry standard for many years. However, well owners soon realized that while the tool joint was well protected, the tungsten-carbide particles were often acting as a cutting tool against casing, causing extreme rates of wear and occasional total casing failure.  To address the critical need for a casing-friendly hardbanding product that could adequately protect tool joints and other down hole tools, Arnco pioneered the casing-friendly hardbanding industry by utilizing an advanced alloy from it’s sister company Alloy Products Group, a subsidiary of Triten Corporation.

Since that time, the drilling industry has become increasingly complex, requiring the need for more advanced alloys that address a spectrum of hardbanding needs from high durability, to low casing wear to ease of use and compatibility with other hardbanding materials in the field. Competitive hardbanding products must now be able to protect drilling and casing components, but also withstand extreme pressures and temperatures experienced in today’s critical wells.

Arnco has invested heavily in R&D resources and aligned with technology partners who are able to provide superior alloy design methodology to quickly address the changing needs of the industry.
