Floating/Shore HDPE Pipe
Floating/Shore HDPE Pipe is made from high density polyethylene resin. It has high rigidity and toughness, with little resistance but high mechanical strength. It has ultra-high wear resistance, abrasion degree is 4-8 times of steel pipe, useful life can reach more than five years. It is very light so it's easy to install and transport and then save construction time.
Total Length ≤12m; Working pressure and inner diameter can be customized.
HDPE pipes, equipped with or without collars and swivel flanges. Ideal in combination with pipe floater for slurry and sand dredging applications.

Feature:
1.It is only one-eighth as light as the steel pipe.
2. through the flange connection, easy installation, disassembly, transportation, shorten the start time, improve efficiency.
3.Good flexibility, tension, high strength, elasticity, tube wall folded in half, extrusion, not easy to be broken by external impact, connection between pipes and pipes, easy to bend, 4-8pcs can bend 360 degrees, connected on land, concave and convex surfaces within 30 degrees, can be directly connected.
4.Smooth inner and outer wall, strong wear resistance, 4-8 times of the steel tube, self-lubricity, low friction coefficient, higher transport efficiency, 20%-30% higher than the steel tube.
5. Strong corrosion resistance, sea water, underground, etc. 50 years unchanged.
6.Strong uv resistance, anti-aging ability, service life is much longer than iron pipe, PVC pipe, nylon pipe and ordinary plastic pipe.
7. patented connector, movable flange connection, the whole pipe without any weld, pipe to pipe between the direct bolt connection, can ensure in the long-term use, often installation and disassembly process without deformation, fracture, and leakage, to ensure efficient delivery.
8. The service temperature is from -40℃ to 60℃, which can adapt to severe climate temperature changes. Whether in water or on land, the project cost is low, the efficiency is high, and it is more convenient for long-term use.
