Long term production of HDPE small diameter corrugated pipe threading pipe

3、 Characteristics of PE bellows
· High rigidity, pressure strength higher than ordinary bare plastic pipe of the same specification; 　
· The weight is half of the ordinary plastic pipe of the same specification, which is convenient for construction and reduces the labor intensity of workers; 　
· Good sealing, which can show its advantages when used in places with high groundwater level; 　
· The corrugated structure can strengthen the resistance of the pipeline to soil load and facilitate continuous laying on uneven ground; 　
· The engineering cost of using double wall corrugated pipe is 1 / 3 lower than that of ordinary plastic pipe; 　
· Corrosion resistance; 　
· Good insulation; 　
· It has the advantages of smooth inner wall and long service life

1、 Introduction to PE double wall corrugated pipe
PE double wall corrugated pipe has 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

Under the condition of equal 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 HDPE Double wall bellows

Long service life of HDPE Double wall bellows: the service life of PE bellows can reach more than 50 years under the condition of being free from sunlight and ultraviolet rays
