Petroleum Machinery

Drill pipes, centralizers, drill collars, sucker rods, TC bearings, screws, plungers, etc., as the main tools for petroleum drilling, operate in harsh environments. They are exposed long-term to corrosive environments such as hydrides and sulfides, while also enduring complex alternating stresses and erosion from large amounts of mud and completion fluids, making them prone to failure and damage. Laser cladding technology can efficiently solve the common problem of rapid failure of petroleum drill strings/tools. Its comprehensive performance surpasses traditional spraying/welding processes, enabling rapid repair of wear-resistant bands on workpieces, significantly improving corrosion resistance and wear resistance of the wear-resistant band surface, thereby extending the service life of drilling tools.
