127mm Drill Tubes Underground Drill Pipes of Different Lengths for Rock Drilling and Rock Blasting
Key features of a high quality DTH pipe are durability, accuracy and manage ability. KSQ pipes are made from cold drawn piping, providing a superior surface finish and tolerance compared to conventional pipes made from hot rolled piping. This drastically reduces the risk of scaling from the pipes entering the hammer, a major cause of premature hammer failure.

Product Advantage:
High quality tubing
Secoroc tubes are made from cold drawn tubing, providing a superior surface finish and tolerance compared to their hot rolled counterparts. Our solution drastically reduces the risk of scaling – the cause of so many premature hammer failures.
No weak links
Traditionally, the threads and the joint between the tube and the end-pieces are vulnerable. To combat the problem, we’ve friction-welded the joints for maximum strength and heat-treated the end-pieces for optimum durability.
Never losing the thread
Heat-treating the threads ensures not only a long service life, but also simplifies joining and breaking – thereby cutting cycle time. To meet varying demands, we provide a selection of API threads. For applications where foam injection is used, we recommend the IF thread. Naturally, we also offer a wide range of subs and crossovers – all made of high quality steel and heat-treated in the same way as tube end-pieces.
