HDPEDouble-WallBellowsN/APEHollow bellows80Early in the decade, it was first successfully developed in Germany. After more than a decade of development and refinement, it has evolved from a single variety to a complete product line. The production process and usage technology are now highly mature. Due to its superior performance and relatively economical cost, it has been promoted and applied in developed countries such as Europe and the United States. Double-Wall CorrugatedPipe materialA new type of lightweight piping material made from high-density polyethylene, featuring light weight, high pressure resistance, excellent flexibility, quick installation, and long service life. Its superior wall structure design significantly reduces costs compared to other piping materials. Moreover, due to its convenient and reliable connections, it is widely used globally and extensively replaces concrete and cast iron pipes.
Application Range
1Municipal drainage and sewage pipeline engineering systems
2Subterranean drainage and sewage systems for apartments and residential complexes.
3Highway pre-buried pipelines, underground drainage networks for golf courses.
4Agricultural irrigation and drainage projects, including water conveyance and flood control systems.
5Chemical, mining, and for fluid transportation and ventilation purposes.
6Protective sleeves for underground pipelines and communication cables, etc.
Industry Advantages:
1Unique structure with high external pressure resistance, impact resistance, flexibility, smooth inner wall with low friction, allowing for greater flow rates through pipes of the same inner diameter; socket and spigot joints for flexible connections, easy to install, high reliability, and leakage resistance.
2Lightweight, quick installation, cost-effective.
3Service life of underground installation exceeds fifty years.
4Polyethylene is a carbon-hydrocarbon polymer with non-polar molecules and is resistant to acid and alkali corrosion.
5Made from eco-friendly materials, non-toxic, non-corrosive, non-scaling, and recyclable for reuse.
6Wide temperature range applicable.-60℃In environments where pipelines do not rupture, the maximum temperature of the transported medium is60℃。
7The comprehensive construction cost is roughly equivalent to concrete, with low operation costs.
8No foundation required in good soil conditions.
