Water well drill rod production process
The drill rods produced by our company are all processed using
materials produced by well-known large steel enterprises in China,
such as Baosteel BAOSTEEL, Angang Steel, Xining Special Steel
XINING SPECIAL Steel, and Henggang. The heat treatment of the
materials is carried out using an integrated non oxidizing furnace,
and all thread processing is carried out using professional CNC
machining. All threads are equipped with thread gauges that meet
international standards, and the rod body and tube ends are
thickened internally. After friction welding, tempering treatment
is carried out, so the quality of the processed drill rods is
stable and reliable, and the service life is greatly extended. The
drilling rod of the water well is welded with a friction welding
machine, which has high strength, good elasticity, is not easy to
bend, and is firmly and reliably connected to ensure quality.

Water well drill rod · structural composition
The water well drill pipe is composed of a barrel, a male joint,
and a female joint. The rod cylinder, male joint, and female joint
have axial holes, and the rear end of the male joint and the front
end of the female joint are inserted into the axial holes of the
rod cylinder through interference fit from both ends of the rod
cylinder; There are shaft shoulders on the male and female joints
of the water well drilling rod, and the end face of the rod
cylinder is welded to the shaft shoulder end face of the male and
female joints. The water well drill rod is a new type of rod that
is connected to the male and female joints through radial
interference fit and welding from the axial end face. Therefore,
the water well drill rod has high torsional strength and can meet
the needs of shallow wells for drilling rigs.
Water well drill rod · Precautions for use
Because there are different types and models of drilling rods for
water wells, it is necessary to choose the most suitable type and
model for use during construction in order to achieve the best
results. When choosing water well drill rods, it is necessary to go
to a reputable and large-scale manufacturer to ensure quality. In
order to prevent water blockage during use, it is necessary to
check the formation, ensure timely water delivery, and ensure
accurate design before using this equipment. In addition, if the
water well drill pipe is twisted during use, it is more likely due
to the manufacturer's use of suboptimal materials in the production
of this equipment. Therefore, in order to achieve good results,
customers need to pay more attention when purchasing to ensure its
effectiveness.
