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.
