HDPE pipe details description:

HDPE winding structure wall pipe (type B), also known as HDPE structure wall type B pipe, Clara pipe type B, is a kind of high density polyethylene (HDPE) as the main raw material, after melting and extrusion, through special equipment to spiral wound, extrusion molding hollow structure drainage pipe. Its structure is composed of an inner layer, a reinforcing layer and an outer layer. The inner and outer layers are usually smooth HDPE layers, with good corrosion resistance, wear resistance and chemical resistance, and the reinforced layer is formed by the HDPE strip through a special winding process, through multiple layers of winding and welding, so that the pipe has a high ring stiffness and compressive strength.

HDPE pipe material characteristics and advantages:

Excellent physical properties:
Made of high-density polyethylene (HDPE) material, it has high strength and toughness, can withstand greater external pressure and impact load, and is not easy to break and deformation. At the same time, HDPE material has good wear resistance, can resist the erosion of sand and stone particles in the water flow, and extend the service life of the pipeline.
Good chemical resistance:
HDPE is an inert material, has excellent corrosion resistance to acid, alkali, salt and other chemicals, can be used to transport a variety of corrosive media, such as industrial wastewater, chemical raw materials, etc., is not easy to be corroded by corrosive media, reducing the cost of pipeline maintenance and replacement.
Excellent environmental stress cracking resistance:
It has good environmental stress cracking resistance, can adapt to different environmental temperature and humidity changes, and is not easy to crack or break the pipeline surface due to environmental factors during long-term use, ensuring the stability and reliability of the pipeline system.
Unique structural design:
Generally used winding structure, this structure makes the pipe has a high ring stiffness, can withstand greater earth pressure and ground load. At the same time, the winding structure can also effectively improve the deformation resistance of the pipe, even under poor geological conditions such as soft soil foundation, it can maintain better shape and performance.
Good hydraulic performance:
the inner wall of the pipeline is smooth, the roughness coefficient is small, and the flow resistance is small, which can improve the flow transmission efficiency and reduce the head loss. Under the same pipe diameter and flow condition, compared with the traditional pipe, the energy consumption can be reduced and the operating cost can be saved.
Easy and reliable connection:
electric fusion connection or hot melt connection is usually used, the connection process is simple, the operation is convenient, the connection part is firm, the sealing is good, can effectively prevent water leakage and leakage problems, to ensure the safe operation of the pipeline system.
Convenient construction:
light weight, easy to transport and install, can greatly reduce the difficulty and labor intensity of construction, reduce construction time and cost. At the same time, the pipe has good flexibility, can be laid according to the terrain and landform, and adapt to a variety of complex construction environment.
Superior environmental performance:
HDPE material is non-toxic, tasteless, will not cause pollution to soil and water, in line with environmental protection requirements. Moreover, the pipe can be recycled and reused, which is conducive to the recycling of resources and environmental protection.
Long service life:
under normal conditions of use, the service life of HDPE pipe can reach more than 50 years, compared with other materials of the pipe, has a long service life, reducing the frequency of pipeline replacement and maintenance, and reducing the cost of the entire life cycle.

HDPE pipe 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.
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.
