1. The pipe weight is only 0.94-0.96g/cm3, which is the lightest of all buried pipes at present, about 80% lower than that of concrete pipes. It is convenient for construction, short in construction period, and has low requirements on the construction site.
2. The outer wall of HDPE pipe is of hollow rectangular structure, which has excellent compression resistance. The ring stiffness is 4-8kpa.
3. The inner wall of HDPE pipe is smooth, and the roughness coefficient is only 0.009, which makes the water flow more smooth and avoids waste accumulation. Under the same slope laying conditions, the flow rate and flow rate are higher than the concrete pipe
4, with good toughness and plasticity, concrete pipe and PVC pipe can not be compared
5. Good water tightness. The rubber sealing ring is used to take over the pipe in the way of multiplication and insertion to ensure that the sewage does not leak
HDPE pipes are made of inert high density polyethylene, which can effectively resist the corrosion of industrial and domestic sewage, and the service life can reach more than 50 years.
