Roschen Drill pipes that are used in applications such as DTH/ RC/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.

Tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.

RC Hammer Bit, DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.

Roschen HDD performs several inspections at various stages throughout the manufacturing process to ensure quality. All of the tubes used in the manufacturing process are full length EMI and/or Ultrasonic inspected before welding occurs. Roschen HDD also performs destructive testing on every heat treat order and every weld order at the frequency required in the operating procedures, API 5DP and all other applicable specifications.

The life of the drill string is maximized by designing pipe that is resistant to fatigue. Fatigue stress is primarily concentrated in areas where there is a sudden change in geometry. I

Roschen HDD utilizes a friction/Inertia weld process to weld the tool joints to the tube body of the drill pipe. This process involves both friction welding and inertia welding within the same operation. The drill pipe tube is places in a fixed position while the tool joint is placed in a spindle, with a flywheel. The tool joint is then spun at a high rpm determined by the size and the weld area. Once the appropriate speed is reached the tool joint is then is pushed against the tube body.

Friction Welding is expert at rotary friction welding drill pipes. Our ability to join dissimilar metals, thicknesses, and shapes makes our process the perfect solution in drill pipe manufacturing. Tool joints can be constructed of higher grade, thicker or solid metal versus the pipe body, saving tremendous cost overall.

Integrated directional drilling pipes adopt R780 tube materials produced by Baosteel. For different specifications of tube materials, end upsetting and integral heat treatment processes are carried out according to various technologies in order to ensure the mechanical properties of different specifications of drilling pipes.
