RELONG Polyethylene dredging pipe (HDPE Pipe) is one of the latest applications of polyethylene pipes. HDPE Pipes are manufactured and welded with two HDPE flange adapter and two steel flanges, which also called as "HDPE flanged pipe", from which two pipes can be connected together easily by flanges. Polyethylene dredging pipe produces with common standards of polyethylene pipe and these two pipes have flange head. Polyethylene flanges are provided for dredging, have cross-sections which accelerate and smooth fluid flow and reduced the pressure on the pumps. Polyethylene pipes (HDPE Pipe), due to their advantages and high mechanical and chemical resistance is the best choice for fluid transfer systems in the dredging projects.

1. The weight of HDPE pipe is light, only one-eighth of steel pipe. The pipes are connected with flanges.
2. The pipes are connected directly. The bending degree of 4 to 8 pcs of pipes can be 360 degrees. It is of good resistance of storms and waves. On land, the pipes can be connected in the area where the uneven surface is within 30 degrees.
3. The material is of high corrosion resistance to be able to float in seawater for 50 years. Also, it is anti-aging and it can be used for 5 to 8 years according to the amount of sediment.
