Double-walled bellows

HDPE Plastic Large Diameter Steel Reinforced Polyethylene Spiral Corrugated Pipe

Published by shentong 2024-06-20

Product Description



1. Strong resistance to external pressure: the annular corrugated structure of the outer wall greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this aspect, HDPE double-wall corrugated pipe has obvious advantages over other pipes.
2. Low project cost: under the same load condition, the HDPE double-wall bellows only need a thinner wall to meet the requirements.Therefore, compared with the solid wall tube of the same material specification, it can save about half of the raw material, so the cost of HDPE double wall bellows is also lower.This is another outstanding feature of the pipe.
3. Convenient construction: due to the light weight of HDPE double-wall corrugated pipe, it is convenient to carry and connect, so the construction is quick and the maintenance is simple.
4. Long service life: the service life of HDPE double-wall bellows can be more than 50 years under the condition of not being exposed to the sunlight and ultraviolet ray.
