New custom material of the drill pipes

 

New type material of drill pipes has been developed in cooperation with professional manufacturer. The loading capacity of the drill pipes has been increased greatly because of the high tensile strength and good impact toughness of the material. The service life of drill pipes is longer than usual.

 

The screw thread structure with patented technology

 

The structure that is designed by dual-thread of one tooth per inch and dual steps contacted tightly reduces lifting force which is transformed from torque greatly. The possibility of thread gluing the threads is also decreased enormously.

 

The equal strength constructions design

 

The design of equal strength constructions can reduce the local peak stress of drill pipes, and improves the anti-fatigue ability of the drill pipes. The weight is also less than common.

 

The replaceable stabilizer blocks

 

The body of stabilizers can be used for long time by changing stabilizer blocks easily. They will save your much money of the production.

 

Raiseboring steel

 

The steel used in the production of our drill rods is vitally important because rods must be able to withstand tremendous loads. Understanding that not all steels of a specific grade are produced to the same quality level and knowing the catastrophic effects of a drill string failure, we are committed to providing value to you through high-quality products demonstrating durability and strength.
