Several features of double wall Corrugated Pipe bellows

Strong resistance to external pressure
The outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this performance, HDPE Double wall corrugated pipe has obvious advantages compared with other pipes.

Low project cost
Under the condition of the same load, HDPE Double wall corrugated pipe only needs a thinner pipe wall to meet the requirements. Therefore, compared with the solid wall phase pipe of the same material specification, about half of the raw materials can be saved, so the cost of HDPE Double wall bellows is also low. This is another outstanding feature of the pipe.

Convenient construction
Due to the light weight of HDPE Double wall bellows and convenient handling and connection, the construction is fast and the maintenance is simple. In the case of tight construction period and poor construction conditions, its advantages are more obvious.

Small friction coefficient and large flow
HDPE Double wall corrugated pipe made of HDPE can pass through greater flow than other pipes with the same diameter. In other words, HDPE Double wall bellows with relatively small diameter can be used under the same flow requirements.

Low temperature and impact resistance
The embrittlement temperature of HDPE Double wall bellows is – 70 ℃. In general, it is unnecessary to take special protective measures during construction under low temperature (- above 30 ℃), which is convenient for construction in winter, and HDPE Double wall bellows has good impact resistance.

Good chemical stability
Because HDPE molecules have no polarity, they have excellent chemical stability. Except for a few strong oxidants, most chemical media do not damage them. Generally, the soil, electricity and acid-base factors in the use environment will not damage the pipeline, breed bacteria and scale, and its circulation area will not decrease with the increase of operation time.

Long service life
The service life of HDPE Double wall bellows can reach more than 50 years without sunlight and ultraviolet rays.

Excellent wear resistance
Tests in Germany have proved that the wear resistance of HDPE is even several times higher than that of steel pipe.

Proper deflection
A certain length of HDPE Double wall bellows can be slightly flexed axially, not affected by a certain degree of uneven settlement of the ground, and can be directly laid in a slightly non straight groove without pipe fittings, etc.

Performance and advantages of our equipment: The corrugated pipe line is the 3rd generation of improved product of Jwell. The output of the extruder and the production speed of the pipe are greatly increased by 20-40% compared with the previous product. Online belling can be achieved to ensure the performance of the formed corrugated pipe products. Adopts Siemens HMI system.
1. The newly designed closed molding machine adopts a special high-efficiency cooling system for forming aluminum modules, which greatly improves the cooling efficiency in the production of corrugated pipe products;
2. High-speed, high-output single-screw extrusion machine supporting a professional design of the corrugated pipe extrusion mould to achieve large-scale stable extrusion;
3. Good interchangeability of the module; the aluminum forming module uses LY12 high-quality alloy aviation aluminum material with copper content ≥ 5%, precision pressure casting process, high density material, no light pores,long-term use is not easily deformed. Can customize various module waveform schemes according to the user’s requirements;
4. Supporting automatic DWC cutter, computer control, accurate cutting position, stable running and easy to operate.
