API Standard DTH Drill Pipe DTH Drill Rods For Water Well Drilling

API Standard DTH Drill Pipe DTH Drill Rods For Water Well Drilling

We adopts Chinese famous large steel enterises production of material to produce dill pipes, and heat treatment of materials by using an integrated multy-processing furnace, professional CNC machining was applied in all of the connection thread processing, all the threads are configured thread gauge, which are in accordance with international standard, Internal thickening technology has carried on the tempering process after friction welding, so the processing quality of drill pipe is stable, reliable, use cycle greatly extended. We can process different length, diameter and wall thickness and material of API standard thread rod, we also can design and manufacture drill pipe according to customers' requirement of material, length, wall thickness and connection thread.

Product Description:

DTH drill rods (also called as drill tubes or drill pipes) are the mechanism to transmit impact force and rotation torque to DTH hammers and bits, as well as offer pass for the air flow. In principle, the lighter the rod is, the better it is for the drilling operation. So a thinner one is always preferable than a thicker one if other parameters were the same. While in the mean time, the yield strength and the tensile strength must also be taken into accounts, which means relatively rod wall thickness would be needed to obtain enough strength. Of course, once the thickness is rigidly requested as thin as possible to minimize the drill string weight, there is also another method to get optimum drill tubes that using better grade steels.

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.
