Friction-welded Drill Pipe What are the manufacturing process principles?

1. The drill pipe casing undergoes cold-drawing processing, ensuring a positive wall thickness tolerance and uniformity across the entire wall. ±0.15 mm, The connector is 42CrMoA After precision machining, the material undergoes vacuum gas nitriding treatment, enhancing the hardness and wear resistance of the drill pipe joints.

2, To ensure the interchangeability and precision of drill pipe connections, all joint threads are machined using high-precision CNC lathes and imported forming tooling. Weilida Exploration Machinery Co., Ltd. Friction-welded Drill Pipe , possessing 80 Tons, 200 Tons, 320 Ton Friction Welding Machine 3 Tai utilizes continuous inertia friction welding technology to join drill rod joints with the drill rod body, with welding parameters monitored by computer to ensure the superior quality of the drill rods.

3、 Friction-welded Drill Pipe Here are a few examples: Domestic applications of drill pipes: Drill pipes are widely used in mining operations, geothermal well construction, and water well drilling.
