HDPE Pipes and Fittings For Mining details description:

HDPE Pipes and Fittings For Mining 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 Pipes and Fittings For Mining is widely used in the pipeline system of mine water transmission, drainage, ventilation, slag transportation and other mining projects. HDPE Pipes and Fittings For Mining 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 Pipes and Fittings For Mining 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 Pipes and Fittings For Mining 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 Pipes and Fittings For Mining 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 Pipes and Fittings For Mining 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.

This product flyer is intended for reference purposes. It should not be used in place of the advice from a licensed Professional Engineer. Nominal pressure (PN) is based on C = 1,25 and an operating temperature of 20°C. Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. Actual ID will vary. When designing components to fit the pipe ID, refer to pipe dimensions and tolerances in the applicable pipe manufacturing specification. To obtain pressure in psi, multiply bar by 14.5 (1 bar ≈ 14.5 psi).
