HDPE double-wall corrugated pipes are formed through a single extrusion process, featuring a corrugated outer wall and a smooth inner wall. They offer excellent performance at a relatively economical cost, making them an ideal substitute for traditional drainage and sewage pipelines. They are widely used in underground sewage and rainwater collection systems for municipal construction, mines, building ventilation, electrical and cable sheathings, farmland, orchards, forest belt irrigation and drainage networks, leachate pipelines in waste treatment plants, chemical wastewater discharge networks, flood drainage and flood discharge pipelines for hydraulic engineering, pre-buried pipelines for railways and highways, and water-permeable and drainage pipes.

HDPE double-walled corrugated pipe specifications: DN110-800mm

HDPE double-walled corrugated pipe applications:

1. Municipal engineering for rainwater and wastewater discharge; industrial wastewater discharge, residential community drainage projects; cable and wire sheathes.

2. Agricultural irrigation and alkali soil transformation; Mine ventilation and petrochemical industry; Mine ventilation and drainage projects.

3. Urban Greening: Golf Courses; Salt Industry Brine Transportation; Fishery Water Supply

Features of HDPE Double-Wall Corrugated Pipe:

1. Unique structure, high strength, resistant to compression and impact; smooth inner wall with low flow resistance; easy to connect, with tight joints and no leakage.

2. Lightweight, quick installation, low operation costs, cost reduction, easy and fast setup.

3. Polyethylene is a carbon-based hydrocarbon polymer, with non-polar molecules and is resistant to acid and alkali corrosion; it has an underground service life of over fifty years; the raw material is a green and environmentally friendly material, non-toxic, non-corrosive, and non-scaling, and is recyclable for reuse.

4. Wide temperature range applicable; pipes do not burst at -60℃; the high temperature of the conveyed medium is 60℃.

5. Excellent resistance to rapid crack propagation, high stress crack resistance, and low sensitivity to scratches.

6. High-tensile pipe material with elongation at break exceeding 500%, highly adaptable to uneven settlement of pipe foundations; no foundation required under good soil conditions.

7. Corrosion and wear-resistant; long service life; excellent flexibility; strong adaptability to various regions.
