Product Description

Drill pipes that are utilized in applications like DTH/ DTHR/ DR essentially comprise of a steel tube with a pin at one finish and a box on the opposite. the work of the drill pipe is to transmit motion torsion and thrust from the oilrig rotary head to down hole drilling tools. 

DTH drill tubes are used for connecting DTH hammer and DTH button bits; they're made up of seamless tubes. per totally different application, totally different diameters of drill tubes are required, basically, smaller DTH hammers want smaller DTH drill tubes, vice avers. sometimes we have a tendency to are providing 50mm, 60mm, 76mm, 89mm, etc. ALL DTH drill tubes are friction welded, and typically the threads are normal API connections,like23/8" API REG thread, three 1/2" API REG thread or API IF thread, etc.
