The Dredging Floater is made from medium density polyethylene material with excellent flexibility, inside is filled with high strength polyurethane foam. With reasonable structure and good performance, the MDPE floater is widely used for HDPE Pipeline and Steel Pipeline.
Property of floater:
1.Good flexibility, and excellent impact resistance, particularly suitable for the installation in the sea.
2.Light weight, easy for installation and movement, with much lower transportation costs.
3.Corrosive Resistance, longer working life, it could work 3 times longer than steel pontoons.
4.The costs and performances are much better than steel pontoons, with more competitive price.
