Workshop for Drill Rods and Subs
Machining of Drill Rods and Subs

    Our pipes can be cut to your exact size requirements. This machine allows two pipes to be cut in a single pass for increasing efficiency.

  • Both the drill rods and subs will undergo friction welding and medium-frequency induction heating operations to ensure drilling tools of superior quality.
    Friction welding is a process that allows for seamless welding of pipes and connectors by using a high-speed extrusion system. It can improve weld quality when compared to traditional electric welding process.


    We can produce a diverse selection of subs to meet your needs. Customization service is available upon request.
