Friction welding drill rod(DTH)

Product Introduction

D Miningwell equips all rock drilling equipment with high-quality friction welded drill rods. The threads, rod bodies and welded joints of the drill pipes have been rigorously processed.

Thread: We can produce all threads that comply with API international standards, and guarantee precision processing. The thread material is 35CrMo, and it has undergone high-quality heat treatment and nitriding treatment to ensure the hardness and service life of the thread.

Rod body: We can supply drill rods with diameters of 42mm-203mm, and the maximum length can be made up to 12 meters. We choose DZ40, R780, G105, S135 and other rod materials according to the needs of different customers and the use scenarios of drill rods, and the wall thickness can be 4.5mm-12mm.

Welding joint: Each drill pipe has undergone a pier thickening process, and the maximum inner/outer pier thickness can be up to 24mm, which increases the friction welding area and ensures the stability of the welding joint.
