Description

Male to Female Down the Hole Well Mining Pipe Adapter Special Designed DTH Drill Sub

DTH Drill Rods (Tubes/Pipes) and Sub Adaptors:

KSQ has DTH drill rods with several different thickness designs for each diameter, made from different grade steels for selection. So, in practice of field drilling, under different condition, there may be in need of different kinds of drill rods for particular application. For example, the thicker ones with general high quality grade steel for drilling hole of average depth, such as blasting holes; and the thinner ones with better grade steel for drilling hole of very deep, such as drilling for ground thermal. Moreover, the DTH drill rods are also well heat-treated, precision manufactured, and friction-welded.

Product Description:

Crossover sub is made from 35CrMo/40Cr/4137H/4145H chrome molybdenum alloy steel, whose chemical composition is strictly controlled. All connections are protected by a phosphate or copper surface coating to minimize galling. It can be divided into the following three types according to the specification and usage.

A: Straight OD Subs: One OD for crossover sub.

B: Reduced section subs: Two ODs for crossover sub.

C: Left hand subs: left hand rotating for crossover sub thread.
