Choosing the Best Hardbanding Wire

The best hardbanding wire chosen for your drilling operation will have a positive impact on your costs and profit. Different situations call for different hardbanding wire. Factors to consider include your drilling conditions, hardness, coefficient of friction, and the degree to which the wire accommodates reapplication.

Drilling conditions

If you are using a casing for your drilling operation, do not select a hardbanding wire with tungsten carbide. Although the tungsten carbide will lead to excellent hardness, it will create too much friction against your casing, especially in cases where 90-degree turns are needed. Rather, select a wire that will create a smoother surface.

Hardness

Select a hardbanding wire with a hardness of not more than 60, but within about 5-10 HRC to that hardness. Hardness in that range will result in a longer service life for your pipes.

Friction

Lower levels of friction will also result in longer-lasting drill pipes that are less expensive to repair and maintain. This will also allow firms to replace their drill pipes less often. High levels of friction make drill strings more vulnerable to abrasion and high temperatures which further increase stress on the drill pipe. Friction reduction becomes especially important when casing is used.

Reapplication

To maximize the endurance of hardbanding in severe conditions, select wire that can be reapplied when necessary. Welders can reapply some types of hardbanding wire several times. However, they must ascertain wire compatibility before reapplication.

Cracking

Cracking can cause spalling, which is the breaking off of welded deposit. This type of failure can decrease the life of your drill pipe by making the welded surface a less effective insulator, and pieces of deposit may even cause damage to pipes or casing. Cracking also interferes with reapplication.

Amount of splatter

Welders prefer wire that splatters less. Less splatter means less clean up time and better, more comfortable use of welding equipment.

What makes Hardbanding by Kooben a good choice

Several factors make HBK wire the best hardbanding wire in the industry. None of the wires that HBK provides contain tungsten carbide, so they are ideal choices for operations with and without casing. Though HBK 100 and HBK 300 do form deposits with micro-cracks, none of our wires will result in cracks that affect performance or resurfacing ability. HBK 150 grade wires do not form any cracks whatsoever. All of our products have hardnesses near 60 HRC, ensuring they will stand up against the most severe drilling conditions. HBK products are also compatible with Arnco hardbanding wire of the same grade.

HBK 150 hardbanding wire ensures that wear against casing is kept to a minimum. HBK 100 and HBK 150 grade wires do not require shielding gases. HBK 300 grade wires also reduce splatter for the convenience of the welder.

Finally, competitive pricing makes HBK wire an excellent choice for making drilling projects more profitable.
