1、 Introduction to PE bellows
HDPE Double wall corrugated pipe is a plastic pipe with HDPE (high density polyethylene) as the main raw material, which is extruded by the inner and outer extruders respectively
It is formed at one time, the inner wall is smooth, the outer wall is trapezoidal corrugated, and there is a wall sandwiched hollow layer between the inner and outer walls
The pipe is suitable for a wide temperature range (+ 60 ℃ - 20 ℃)
Due to its unique structure, the product has many advantages, such as high ring stiffness, high strength, light weight, sound insulation and shock absorption, high UV resistance stability, long service life, good bending, pressure resistance, high impact strength, strong corrosion resistance, cold and heat resistance, etc
the sealing rubber ring is embedded in the trough at both ends of the pipe, which has good waterproof and sealing performance, and can be laid in sections with poor geology, Fast construction, widely used in communication, telecommunications, cable laying

3、 Characteristics of PE bellows
The product has unique structure, strong compressive capacity, smooth inner wall, large overflow, good bending performance, can adapt to the uneven ups and downs of soil, long service life, and can be used for more than 50 years
Large diameter and high strength: due to the use of U-shaped steel strip composite material, the ring stiffness of the pipe is greatly improved without increasing the cost
Under the same weight, the strength of the pipe is significantly higher than that of the wound pipe and Clara pipe
It can solve a series of problems such as heavy load, and the advantages of large-diameter pipes are more obvious
At present, the diameter of pipes produced by us is from 800mm to 2000mm, and the ring stiffness is maintained above 12
5kn/m2, which is lighter and stronger than cement pipes and other plastic pipes
Reliable performance: the lamination of each layer is carried out in the molten state of plastic, which is completely different from the winding pipe connecting pipe (hollow wall pipe), so the lamination fastness of each layer is very reliable
The surface of corrosion-resistant long-life steel strip is specially pretreated to enhance the anti-corrosion ability of steel and the adhesion between steel and plastic, and improve the peel strength
When the plastic raw material is fully melted, it is wound and formed, and the overall structure of the pipe is firm and reliable
The use of special materials and processes not only solves the problem of steel plate corrosion prevention, but also solves the adhesion between steel plate and PE material, so that the service life of the pipeline is also guaranteed to be more than 50 years
Various connection modes: reliable connection: it can be connected by electrothermal fusion, heat shrinkable belt, internal and external extrusion welding or a combination of various connections, and the connection is firm
Reliable connection can make the pipeline achieve zero leakage
