Atlas Copco API Standard 89mm DTH Drill pipe For Water Well Drilling and Construction

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.DTH drilling enables drillers to reach hole depths that are double of what top hammer drilling can do. This is possible with the use of DTH Pipes and DTH Subs.

Drill pipe is a major drill component which connects rotary system,hoisting system,circulation system with drill collar and bit.Through it the rotary table drives the bit rotation,hook drives bit up and down and drill fluid flows to the bottom forming circle to make the bit breaks rock and reaches continuous drilling.
