Product Description

HDPE Dredge Pipe
It is high density polyethylene (pressure-resistant material, resistance to fold materials), wear-resisting material, anti-aging ultraviolet material etc.
1. The weight is light. Through activities flange bolts to connect, installation and dismantle, transportation are convenient, shorten the time, improve efficiency.
2. Pipe has good flexibility, tensile strength and elastic, pipe extrusion, pack, it doesn't break after internal and external force impact, Plastic pipe can be directly connected, in the water it can bend, 4-8 pieces can bend 360 degrees. Good resistance of stormy waves.
On land of connection, the concave-convex is within 30 degrees of area, can be connected directly, it does not need to repair ground of surface.
3. Pipe has good wear-resistance, it is 4-8 times of steel pipe, use longer, Piping material of corrosion resistance is strong, can soak in sea water for 50 years with no change, Anti-UV, anti-aging, and it can be used for 5-8 years upon sand content.
4. Pipe is assembled with two metal activity flanges at both pipe ends. The entire pipe is without any weld, pipe and pipe are connected by flanges of bolt. Steel pipe lining, can ensure pipe will not deformation and drip when installation and disassembly, ensure transportation engineering of high efficiency.
5. Pipe has smooth outer and inner wall, friction coefficient is tiny, high transmission efficiency than steel pipe 20% to 30%, temperature is used at - 40-60 ° C, can adapt to bad weather changes in temperature.
6. Pipe is either on land or water for using, total engineering cost is low, high efficiency, safer, and more convenient.
