Hardbanding
Drill pipe hardbanding protects drill pipes from abrasion and other wear and tear. Workers typically weld the wire onto the tool joint. The welded metal insulates the pipe from direct contact with the casing or well wall, protecting it from friction.
Drill pipe replacement is expensive in terms of both cost and downtime. Aside from extending the service life of drill pipes and other equipment, drillers can substantially reduce operating costs and minimize time spent on replacing or dealing with worn-out equipment by hardbanding drill pipes. It also protects casing from excessive wear and tear.
HBK provides high quality hardbanding wire at the industry’s most competitive prices. It is also compatable with Arnco products, meaning it can be welded over that company’s hardbanding wire for lasting protection.
Kooben Grade | Description |
---|---|
HBK 100 | A type of ferrous-based flux-cored welding wire. Among the technical characteristics of this grade is the addition of a special alloy which allows good control over coagulation performance and the weld pool. |
HBK 150 | A type of ferrous-based flux-cored welding wire. Among the technical characteristics of this grade is the addition of a special alloy which allows good control over coagulation performance and the weld pool. |
HBK 300 | High hardness averaging 62 HRC, excellent toughness, and high wear resistance. The carbides and other hard phases in this hardbanding wire are closely arranged and dispersed in the martensite. |
