High Performance Friction Welding Drill Pipe For Water Well Drilling /Friction Welding Drilling Rod Drilling Pipe For Well Drilling

 

1. Description

 

Friction welding drill pipe is connected by using two drill pipe friction welding technology together, (under the influence of pressure, through to friction welding workpieces near the interface and its temperature, make the material produces plastic deformation, accompanied by a material to produce plastic flow, through the interface of molecular diffusion and recrystallization and solid-state welding method for welding.)Welding can achieve the strength of the forged tissue, theoretically comparable to the parent material.

 

2. Specifications of drill pipe:

 

Product name Friction welding drill pipe
Diameter 50-159mm
Length 1000mm to 6000mm
Wall thickness 5.5/6.5mm/7.5/8.5mm/10mm
Material High manganese steel
Thread API REG
Application Well-drilling,coal drilling,quarrying
Advantage High performance and high pressure

 

3. Advantages of friction welding drill pipe:

 

1) The optimal combination of drill pipe is realized, the rod body and joint can be made of different materials, and the heat treatment optimization performance is improved.Other forms of drill pipe cannot be achieved.

2) The joint has high mechanical properties and abrasion resistance.Longer service life than other types of drill pipe.

3) Light weight and good flexibility.

4) The drilling fluid channel inside the drill pipe can be designed.The design of the inner hole channel of the threaded probe can fully consider to reduce the hydraulic loss when passing, especially to reduce the loss caused by the threaded joint part, can improve the working efficiency of the drilling fluid system.

5) With the improvement of welding equipment, welding process and technology and the improvement of heat treatment technology, the connection strength of friction welding is higher than that of the base material itself.The welding strength of the weld is higher than that of the base material.

6) Conduct integral tempering and heat treatment on the pier of friction welding drill pipe after it is thick, and its bending resistance and flexibility are greatly improved.
