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.
