NC(NQ) Drill Rod Φ69.9X60.3X5 Wireline Drill Rod for drilling rig
Our drill rods(NQ DRILL ROD) are all manufactured by CNC machines.
They're made of high quality alloy steel with heat-treated. We also
can produce various sizes of casing tubes. Our NC(NQ) drill
pipe/drill rods got most praise from oversea market.
1. high quality alloy tube
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads
strong and ductile geological steel pipe;
solid quality and considerate service;
SINOCOREDRILL 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. We will make sure the
compositions and specifications match the inspection report form
Heat treatment control:
Heat treatment 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. After
heat treatment, strength, hardness, straightness and concentricity
of the treated tubes will be tested in our lab.
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
