Anti-aging, long service life: Polyethylene pipes containing 2-2.5% of uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
Good wear resistance: The comparison of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transport, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have a longer service life and better economy.
Good flexibility: The flexibility of the HDPE pipe makes it easy to bend. In engineering, the obstacle can be bypassed by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation cost.
Small water flow resistance: The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than conventional pipes, while also reducing the pressure loss and water consumption of the pipe.
Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install. The lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
A variety of new construction methods: HDPE pipelines have a variety of construction techniques, in addition to the traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, liners, Construction by means of split pipes, etc., is the only option for some places that are not allowed to be excavated, so HDPE pipes are used more widely.
