HDPE Dredging Pipe
PE pipe
HDPE Dredging Pipe
HDPE dredging pipes are made of high-density polyethylene and designed for transporting slurry, silt and solid-liquid mixtures. They offer outstanding wear resistance, a smooth bore with low resistance and minimal silt build-up. Lightweight, tough, impact-resistant and corrosion-resistant, they use flange connections for easy assembly and transport. Suitable for river dredging, sand extraction and reclamation, port dredging and lake treatment, capable of long-distance transport of sand-bearing slurry with seawater resistance and a long service life.
Specifications
- Material
- HDPE（高密度聚乙烯）
- Connection
- 法兰 + 螺栓连接
- Operating Temperature
- -40℃ ~ 60℃
Features
- Lightweight and efficient: one-eighth the weight of steel pipe, with flange and bolt connections for easy transport, repair and replacement.
- Tough and high tensile strength: does not break under internal or external impact, with strong wave resistance and the ability to bend into a circle assembled from 4–8 sections.
- Outstanding wear resistance: 4–8 times that of steel pipe, and with UV and ageing resistance typically lasts 5–8 years in sand-bearing service.
- Reliable flange joints: metal flanges at both ends with bolted connections that do not deform or leak during assembly and disassembly.
- High conveying efficiency: smooth inner and outer walls with a low friction coefficient deliver 20–30% higher efficiency than steel pipe.
- Wide temperature range: operates from -40°C to 60°C, adapting to harsh weather and temperature fluctuations.
- Low overall cost: lower total project cost than other pipes whether on land or in water.
Applications
- River dredging
- Sand extraction and reclamation
- Port dredging
- Lake treatment
