HDPE mining pipe details description:
HDPE mining pipe is a
pipeline system specially used in the field of mining engineering made of High Density Polyethylene (HDPE) as the
main raw material and made by extrusion molding process. Designed for complex, harsh mining environments, the
product offers high strength, excellent corrosion, wear and impact resistance. HDPE mining pipe is widely used in
the pipeline system of mine water transmission, drainage, ventilation, slag transportation and other mining
projects. HDPE mining pipe can run stably in high strength underground environment, and effectively improve the
safety and economy of mine engineering.
Compared to traditional steel pipe, cast iron pipe and PVC pipe, HDPE
mining pipe not only has a longer service life and lower maintenance costs, but also has significant advantages in
terms of transportation, installation and system safety. Its connection methods are mostly hot melt butt, electric
melt connection or flange connection, to ensure that the interface strength is high, sealing is strong, no leakage,
suitable for special needs such as mine subsidence, small space and continuous transmission.
HDPE mining pipe material characteristics and advantages:
Good health performance:
the HDPE material itself is non-toxic, tasteless, will not pollute the transported medium, in line with the mine
drinking water transmission and other application scenarios with high water quality requirements.
Excellent insulation performance:
It has good electrical insulation performance, which can effectively avoid safety accidents
caused by static electricity accumulation, especially suitable for flammable and explosive environment such as coal
mine.
Good low temperature resistance:
it can still maintain good flexibility and mechanical properties in low
temperature environment, is not easy to crack, and can adapt to complex temperature conditions under the
mine.
Recyclability:
HDPE mining pipe can be recycled after waste, in line with environmental requirements,
reducing the impact on the environment.
Convenient and reliable connection:
the use of hot melt connection,
electric fusion connection and other ways, high connection strength, good sealing, can effectively prevent pipeline
leakage, to ensure the safe operation of the mine pipeline system.
Low comprehensive cost:
Although the initial
purchase price of HDPE mining pipe may be relatively high, due to its long service life, low maintenance costs, high
transportation efficiency, and low installation costs, the comprehensive cost is low in the long run.
HDPE mining pipe construction method:
Hot melt connection:
The hot
melt machine is used to heat the connection part of the pipe and pipe fittings to a molten state, and then the two
are quickly bonded, cooled and solidified under a certain pressure to form a solid connection. Suitable for the same
material, nominal outer diameter ≥63mm pipe and pipe, pipe and pipe fittings connection.
Electric fusion connection:
the electric fusion pipe is set on the pipe, and the resistance wire in the electric fusion pipe is
electrified through the electric fusion welding machine, so that the resistance wire heats up and the contact
surface of the pipe and the pipe is melted, and the body is formed after cooling. Suitable for various
specifications of HDPE water pipe connection, especially suitable for nominal outer diameter < 63mm pipe or cannot
use hot melt connection occasions.
Flange connection:
The HDPE pipe and flange are connected together by hot
melt or electric melt, and then the two flanges are connected by bolts, and the sealing gasket is installed in the
middle to realize the connection and sealing of the pipeline. The flange connection is suitable for the connection
of HDPE pipes with valves, flowmeters and other equipment, as well as the parts that need to be disassembled
frequently, which is easy to maintain and overhaul.
