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.
