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 storm 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 sea water for 50 years. Also it is anti-aging and it can be used for 5 to 8 years according to the amount of sediment.

1. The assembly, disassembly and transportation are easier, shorten the starting time, raise the efficiency and avoid the troubles of replacement after the welded pipes are damaged by external force. 2. The HDPE pipe has good flexibility, tension, strength and elasticity. It doesn't break after folding, extruding, or internal or external force impact. 3. The HDPE pipe has good wear-resistance, which is four to eight times of that of steel pipe. So it lasts longer. 4. Light weight and ease of installation can reduce installation costs.HDPE Pipe is widely used in many projects: (1) Municipal water supply (2) Commercial & Residential water supply (3) Industrial Liquids transportation (4) Sewage treatmentQuality and advantages of unique products of RELONG, as a superior alternative to old materials and methods has made these products as the first choice of engineers and contractors .
