Adaptors for DTH Drill Rods

Drill pipe adapter 

Drill pipe adapter called drill pipe subs, or drill pipe protection joint

Roschen produced drill pipe joints with double lift shoulder (double top) structure. This structure can enhance the sealing of the joint, so that the pressure of the mud through the drill pipe center pipe does not leak. Greatly reduce the guidance and lift the obstacles, the use of this structure to improve the drill rod tensile, anti-torque strength, so that the female buckle joints will not be deformed.

Optimize the design of the adapter structure, evenly improve the strength and dispersion of the drill pipe pressure, can give full play to the potential of the drill pipe material.

During the process of forging the joint material, the material density is increased and the fiber structure of the material is changed, and the microstructure is enhanced, thereby enhancing its fatigue resistance.

The use of joint nitrides, phosphides, or copper processing to protect the thread corrosion, anti-adhesion, improve the surface of the contact wire anti-fatigue strength.

The tube body upsetting thickening, improve the material and metal structure and improve the impact toughness, to ensure that the comprehensive mechanical properties and friction weld does not break.

In addition, where to buy our company's drill pipe, you can replace the protective adapter for you free of charge.
