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.
