Hydraulic Drilling Rig HDD rock Drill Pipe Construction Horizontal Directional Drill with thread rock drill rods
Technical Parameters of Wireline HDD Drill Rod:
HT-115 is widely used in the trenchless construction to turn on and turn off drilling
tools with diameters from 50 mm to 117 mm.
NO-Dig is developed rapidly these 20 years. We started HDD industry since 2008, and
we are specialized in manufacturing forged one-piece and friction welding drill rod and our rod can be compatible for both of chinese
and oversea drill machines and all terrain machines.We have build a
long-term and stable raw material supplier which is also our
authorised supplier.
All the manufacture processes are checked and controlled by
ourselves,
such as raw material check, end-upsetting, quenching,shot blasting and package.In order to track and review our
processes, we record laser mark on each pipe,for a better after sales survey.

Description:
Wire line Drill Rods With DCDMA standards Heat treatment control 3m /1.5m
Our drill rods and casing tubes are manufactured from the highest quality material, under stringent industry DCDMA standards, and are field tested under a variety of conditions, in order to meet the most rigid demands in during performances and in manufacturing standards.
We will make sure the compositions and specifications match the inspection report form the suppliers.
Raw materials:
30CrMnSiA/XJY850
We only choose the best steel tubes in the market to manufacture
our rods and pipes. Spot check will be conducted after the steel
tubes delivered to company.
Heat treatment control:
Entire-length or ends thermal processed will greatly improve the
material strength and increase the thread wear life of the rods and
casings. We conduct either tru-wall or both ends heat treatment to
the tube body, ensuring superior wear resistance, strength, and
toughness in the most demanding applications.
Thread opening process:
Accuracy of threads will determine the use effects and life time of
drill rod and casings.
CNC latches and form cutter are used in thread opening processing
to minimize error made by anthropic factors.
Additional thread treatment:
Surface of the threads will be cleaned to remove burr adhered after
threads are opened.
Afterwards, the tread surface will be phosphated to improve surface
conditions.
