Coiled HDPE Pipes OD20-110mm details description:

Coiled HDPE Pipes OD20-110mms are flexible pipes made of high density polyethylene (HDPE) material that are stored and transported in compact coils, typically 100-300 m in single coil length and in the pipe diameter range DN16-DN63 (1/2"-2"). Its unique coil design significantly saves storage space, maintains excellent memory recovery after deployment, and maintains flexibility even at -5 ° C, with a minimum bending radius of up to 20 times the diameter of the pipe. Corrosion resistance is its outstanding advantage, it can resist the erosion of various chemical substances, suitable for a variety of harsh environments. Coiled HDPE Pipes OD20-110mms play a key role in urban water supply and drainage, agricultural irrigation, industrial fluid transport and geothermal heating.

Coiled HDPE Pipes OD20-110mm material characteristics and advantages:

Super flexibility and space efficiency: compact coil design, single coil up to 500 meters (DN20 specification), the minimum bending radius of 20 times the diameter of the pipe (DN25 pipe can be bent to Φ500mm), no memory rebound after expansion, still maintain flexibility at -30℃
Good low temperature resistance: Coiled HDPE Pipes OD20-110mm has good low temperature resistance, can still maintain good flexibility and mechanical properties in low temperature environment, not easy to crack, suitable for various engineering applications in cold areas.
Strong anti-aging performance: HDPE material has excellent anti-aging performance, can resist the erosion of natural factors such as ultraviolet light, oxygen, water vapor for a long time, and is not easy to aging, cracking and other phenomena, which can ensure the stability and reliability of the pipeline in the long-term use process.
Hygienic and non-toxic: The high-density polyethylene material used in the Coiled HDPE Pipes OD20-110mm is itself non-toxic and tasteless, in line with the relevant national health standards, and can be safely used for drinking water transportation and other areas with high health requirements, and will not pollute the water quality.
Recyclability: Coiled HDPE Pipes OD20-110mm is a recyclable material, after the end of its service life, it can be recycled, which is conducive to saving resources and protecting the environment, and meets the requirements of sustainable development.
Good wear resistance: Coiled HDPE Pipes OD20-110mm has high hardness and wear resistance, it is not easy to be worn during use, even in some fluid transportation containing particle impurities, it can maintain good wear resistance and extend the service life of the pipeline.

Coiled HDPE Pipes OD20-110mm connection:

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 can not use hot melt connection occasions
. Socket connection: First heat one end of the HDPE pipe to soften it, and then insert the other end into the softening end, and then heat and apply pressure to make the two closely combined. This connection method is suitable for small-caliber HDPE pipes, convenient installation, fast connection speed, but the connection strength is slightly lower than that of hot melt butt and electric melt connection.
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.
PE quick joint connection: This joint has an internal cavity into which the PE pipe can be inserted, sealed and fixed by sealing rings or elastic clasp and other components, suitable for small and medium diameter PE pipe connection.
