Pe bellows is a new type of pipe made of very high density polyethylene, gradually it has developed into a more complete product line. Excellent performance and relatively low cost have become the strong advantages of its development. However, in the actual pe bellows construction method and process, it is not so simple, and the places and matters needing attention are also very much. If you do not pay attention, it may affect the work efficiency and work effect after the bellows. However, many people do not understand this type of pe bellows construction method and the performance characteristics of the pe bellows. Don't worry, let me help everyone to reveal the answer one by one.
Pe bellows introduction
HDPE double-wall corrugated pipe referred to as PE corrugated pipe historical review HDPE double-wall corrugated pipe is a new type of pipe with a circular structure of the outer wall and smooth inner wall, the early 80s in Germany was first developed successfully. After more than 10 years of development and improvement, it has evolved from a single species to a complete product line. At present, the production process and use technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States.
Pe bellows performance characteristics
1, unique structure, high strength, pressure resistance and impact resistance.
2, the inner wall is smooth, friction resistance, large flow.
3, easy connection, joints sealed, no leakage.
4, light weight, quick construction, reduce costs.
5, buried life of more than 50 years.
6, polyethylene is a hydrocarbon polymer, molecular non-polar, acid and alkali corrosion.
7. Raw materials are green, non-toxic, non-corrosive, non-fouling and recyclable.
8, the wide temperature range, -60 °C environment in the pipeline does not break, the maximum temperature of the transmission medium is 60 °C.
9. The comprehensive construction cost is basically the same as that of concrete, and the operating cost is low.
10. There is no need for foundation if the soil quality is good.
Pe bellows specifications
Specifications for pe bellows include: DN100mm, DN160mm, DN200mm, DN300mm, DN400mm, DN500mm, DN600mm, DN700mm DN800, DN1000mm, DN1200mm, etc.
Pe bellows application range
Municipal engineering, underground drainage and drainage of residential quarters; pre-embedded pipelines on the highway; water conservancy irrigation and drainage in farmland; transportation of fluids in chemical industry and mines.

Pe bellows construction method
Before starting the construction, a certain inspection of the pe bellows must be performed to see whether the bellows caused some damage during the transportation process, or whether the quality of the bellows itself is qualified, so as to ensure that the construction effect reaches the best state.
After the inspection, the excavation work should be performed on the construction site. During the excavation, it should be noted that the width of the bottom of the trench is wider than the outer diameter of the pe bellows by more than 0.6m, and the four walls should be neatly arranged. Do not appear too much rocks. At the same time, appropriate drainage measures should be taken during excavation to prevent the phenomenon of soaking and erosion of bellows caused by excessive water accumulation.
After digging, remember to put a gravel-type soil layer on the bottom as a basic protective layer of bellows. Moreover, there are certain standards for the foundation. For example, the thickness of the foundation should reach 0.1m. If the construction site is the foundation of soft soil, the thickness of the foundation should reach 0.2m or more. In the construction process, the foundation should be tamped, and the surface must be smoothed. Remember to reserve the groove in the place where the pipe is based on the interface to facilitate the operation of the interface. It should be noted that the width of the groove is also well-defined. Generally, the length of the groove is preferably in the range of 0.4 to 0.6 meters, and the depth is preferably in the range of 0.05 to 0.1 meters, and its width. The best is 1.1 times the outside diameter of the pipe so that it can better ensure the quality of the construction.
Editor's summary: The construction process of the pe bellows is relatively tedious. Things to pay attention to include the soil quality, depth, and waterproof conditions. Moreover, after the construction is completed, it is also necessary to carry out inspections and monitoring for a period of time to ensure that the construction results reach the best state.
