Description of Forged Welding HDD Drilling Tools HDD Drill Rods /
HDD Drill Pipe:
Non-dig integral forged drill pipes are used to transmit drill
torque and pullback force during the directional drilling project.
The manufacturing process of the pipes is very strict because the
pipes must bear twist, pullback, friction and vibration in the
course of drilling. The raw material used in Double Horse is all
the alloy steel produced
We have different specifications for customer's choice: φ50, φ60,
φ73 ,φ89, φ102, φ114, φ127 ,φ140 ,φ168 .And the length of drill
rods and connection threads can be made totally according to
specific requirements of clients. The normal length of our HDD
drill rods is 1.5m, 3m, 4.5m, 6m.
The pipes are plated with nickel-phosphor to enhance the hardness
and tightness of the threads surface. The finished pipes will be
sent to pass a series of tests such as tests for hardness,
metallurgical structure, physical property, ect. before they are
covered with paint.

Features of HDD Drill Rods:
1). Pipe end upsetting technology, self connecting mode and heat
treatment have been used in the manufacture of this kind of HDD
drill rod. Thus, our drill rods in different specifications possess
excellent mechanical properties.
2). Double-step structure is used for its male and female threads,
so this kind of drill rod has optimal sealing property and after
torsion, there is little transformation in the rod.
3). Chemical plating (electroless plating) is used on the surfaces
of threads so as to improve the hardness of surface and abrasive
resistance of thread.
Quality Control:
1. We have been strictly controlled the quality of our raw
materials, and all of our steel metals are from famous steel mills
(factories). And physical metallographic analysis and chemical
composition test are also used to ensure the quality of raw
materials.
2. Immediate inspection will be done for each production procedure,
and full examination will be implemented for threaded products.
3. Our outsourcing products will also be strictly examined before
utilization.
