Drill pipe protection joint

Drill pipe joints adopt the double ledge (double top) structure.Such structure can enhance the tightness of joints so that the pressure of the mud could realize non-leakage half-way. Greatly reduce the resistance to pilot drilling and back,using this structure improves the torsional strength of drill pipe so that the box thread will not deformed.

After optimal design of equal strength and the dispersion of stress,to give full play to the potential of the drill pipe material.

After forging joint materials,increased material density and change the material of fibrous tissue,thereby enhancing its mechanical properties.

Using joint nitride,phosphide or copper treatment to ensure threaded anti-corrosion,antistick,and improve joint surface fatigue resistance.

Upsetting&thicking to the tube,improving the metallurgical structure and enhancing the impact toughness,ensuring comprehensive mechanical properties and the friction weld seals not be broken.
