Hardbanding
In oil and gas drilling, wear occurs on drill pipe tool joints. These parts are subject to abrasion and if unmanaged, this wear leads to loss of tool joint diameter, reduced structural integrity and increased risk of casing damage.
To manage wear on these components, hardbanding is carried out. This involves applying a weld overlay to the external surface of tool joints to reduce metal loss while maintaining compatibility with casing materials. This extends the drill pipe service life without excessive casing wear or compromising performance.
SOLUTIONS FOR DRILL PIPE TOOL JOINTS
Welding Alloys has a range of consumables for this application called DRILL-GUARD. These wires have been specially developed to extend the service life of drill pipe tool joints and provide the ultimate drilling performance.
We are the only company to produce laser-sealed seamless cored wires for hardbanding applications. Our DRILL-GUARD NB SEAMLESS cored wire features enhanced wire feeding, consistent weld appearance and high wear resistance. This wire is designed to perform in demanding environments.
Tool joint wear occurs primarily through friction and contact with borehole walls and casing. Effective hardbanding must protect the tool joint while minimising casing wear. Our seamless DRILL-GUARD wire is designed to help protect both.
The range also includes DRILL-GUARD CC and DRILL-GUARD NB cored wires, providing excellent wear performance in hardbanding applications.
WHY CHOOSE WELDING ALLOYS?
Our consumables are manufactured to support controlled wear behaviour, reliable welding characteristics and repeatable overlay quality.
Alloy composition, hardness and hydrogen control affect overlay performance and resistance to cracking during welding and in service. Consistent wire manufacture also influences weld stability, bead shape and repeatability, particularly when hardbanding is reapplied during refurbishment.
Because we manufacture our own wires, we control the entire process and maintain consistency from batch to batch. The result is more predictable performance, longer drill pipe life and reduced maintenance.
