Friction Welding Of Submerged Dril Rods For Core Rock Drilling Rigs
The friction welding submerged hole drill pipe is made of 40Cr, and
the quality is stable. The life of the drill pipe is increased by
several times than that of the electric drill. The strength of the
drill pipe is greatly improved after heat treatment.
DTH drill pipe specifications are HC-50 and HC-60. The length of
the DTH drill pipe is 1000mm, 1020mm, 1050mm, 2000mm, 3000mm.
Widely used in all kinds of down-the-hole drilling rigs and
down-the-hole drilling rigs. The DTH drill pipe is welded by
friction welding machine, and the connection is firm and reliable
to ensure the quality.
