HDPE Double-Wall Corrugated Pipe details description:

HDPE double-wall corrugated pipe A type pipe is a kind of plastic pipe with unique structure and excellent performance, HDPE double-wall corrugated pipe is composed of internal and external two layers, the inner layer is a smooth polyethylene (HDPE) pipe, the outer layer is a polyethylene layer with a corrugated structure. This structural design enables the pipe to reduce weight while ensuring a certain strength, and the ring stiffness is relatively high, which can better withstand soil pressure and ground load. Good waterproof performance, can effectively prevent groundwater infiltration into the pipeline system. It is suitable for occasions with large buried depth or large ground load, such as urban main roads, highways and other underground drainage projects, as well as places with high waterproof performance requirements。

HDPE double-wall corrugated pipe material characteristics and advantages:

Excellent physical properties
High ring stiffness: The unique corrugated structure makes it have high ring stiffness, can withstand greater external pressure, is not easy to deform, and can adapt to different buried environments, including areas with large buried depth or large ground load.
Good flexibility: The material has a certain degree of flexibility, can adapt to the uneven settlement of the foundation and the slight deformation of the soil, is not easy to break due to ground movement, and improves the stability and reliability of the pipeline system.
Strong corrosion resistance
Chemical corrosion resistance: HDPE material has excellent chemical resistance, strong resistance to acid, alkali, salt and other chemical substances, can be used to transport a variety of corrosive liquids or in corrosive soil environment, can effectively extend the service life of the pipeline. Aging resistance: It has good aging resistance, anti-ultraviolet radiation, not easily affected by environmental factors and aging deterioration, and can maintain stable performance in outdoor long-term use.
Good hydraulic performance
Smooth inner wall: The inner wall is smooth and flat, and the water flow resistance is small, which can effectively improve the water flow speed and reduce the water head loss, so as to improve the drainage or water transmission efficiency and reduce the possibility of pipeline blockage.
Large flow capacity: under the same pipe diameter, due to its smooth inner wall and special structure, the flow capacity of HDPE double-wall corrugated pipe is larger than that of traditional pipes, which can meet the drainage or water transmission needs of large flow.

HDPE double-wall corrugated pipe connection mode:
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: one end of the pipe is processed into a socket, the other end is processed into a socket, the rubber sealing ring is installed at the socket end, and then the socket is inserted into the socket, and the sealing connection is realized through the compression deformation of the rubber sealing ring.
Heat shrinkable sleeve connection: The heat shrinkable sleeve connection is the use of heat shrinkable sleeve under heating conditions can shrink and tightly fit the characteristics of the pipe connection, to achieve a sealed connection between the pipes.
