Features:
1. The drill rod of China Drill is of many thread types to meet
different drilling needs.
2. Thread compound is a kind of lubricant used to reduce friction
in drilling process..
3. Before drilling, drill rods should be in operation under the
minimum recommended make-up torqueto pressure the box and pin. The
drilling operation torque should be lighter than make-up torque.
4. Drill Rod grease is used to lubricate the drill rod and the hole
which can make a longer tool service life.
5. Drill rods are offered by the bundle.
Specifications:
Standard drill rod here we offer include BQ, NQ, HQ, HWT.
BQ rod 1.5m (5fts), BQ rod 3m (10fts),
NQ drill rod 1.5m (5fts), NQ rod 3m (10fts),
HQ rod 1.5m (5fts), HQ rod 3m (10fts),
HWT drill rod 1.5m (5fts), HWT rod 3m (10fts)
Various thread types of drill rods are available. We will meet your
demand for standard, deep, wide-diameter as well as conventional
drilling.
Besides standard rods, Roschen group limited also provides V-Wall™ rod. Although 30% lighter than a standard rod, V-Wall™ rod increases 30% annular clearance. It speeds up the drilling of 50% and increases efficiency.
There are also genuine drill rod and patented drill rod, HD thread, conventional type as follows:
Genuine drill rod:
1) Genuine drill rod in Roschen group limited is eligible with
general standard for wireline coring. With more than 40 years of
investigation and advanced manufacturing techniques, genuine drill
rod has adapted to market needs.
2) Tubing of genuine drill is made from first-rate solid alloy
steel and can be sold in all DCDMA sizes.
3) Thread of genuine drill is patent tapered and more effective in
making and breaking of rod joints. 30% load efficiency is competent
for average use.
4) Thru-wall heat treatment procedure offers 140% material power
and lengthen thread wear life.
5) Case hardening—China Drill is the only producer of case-harden
threads to minimize friction..
Patented Drill Rod:
1) To ensure a good performance and long service life, our patented
drill rod adopts patented heat treatment procedure as well as
innovative engineering. Patented drill rod is used in requiring
wireline applications to increase efficiency.
2) Tubing of patented drill rod is composed of excellent heat
treated alloy steel with all DCDMA sizes.
3) Thread of patented drill rod includes course thread and fine
thread. The course thread has a favorable effect in making and
breaking. The fine thread contributes to a good performance in thin
kerf wireline systems.
4) Thru-wall heat treatment process of patented drill rod performs
on 175% material strength and increase thread wear life greatly.
5) Case hardening—Roschen Group Limited is the only producer of
case-harden threads to minimize friction welded.
HD Threads:
1) HD threads are used in large-size core drilling. It provides a
powerful, rough thread profile for a tough drilling.
2) Tubing is made from heat-treated alloy steel. It features
long-lasting concentricity, straightness, and provides all DCDMA
sizes tubing
3) The larger, deeper threads give consistent durability. 40% of
load is efficient in drilling large holes.
4) Case hardening—we are the only producer of case-harden threads
to minimize friction.
Conventional drill rod:
1) The conventional drill rod is composed of a tubular body with
friction soldered pin and box. It is widely used in conventional,
geotechnical, environmental and rotational use.
2) The tapered thread is an API thread alike. It is made by using
DCDMA gauges which is beneficial in rod joints application and with
greater pulling load capacity.
3) Mid body tubing is made from superior alloy steel.
4) Conventional drill rod plays the same role as parent material by
omitting the disadvantages of brittle material made by general
welding techniques.
