1100Mpa Extension Strength Raise Boring Drill Rod 1m / 1.524m With Thead Protector

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

The drill pipe adopts equal strength design, which reduces the overall weight of the drill pipe and effectively improves the drilling depth capacity and the fatigue resistance of the drill pipe.

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.

We can provide Mill certificates: Chemical compostition, Mechnical properties, UT test, MPI test etc.
