The pipeline water transmission system uses the pipe network for water distribution and irrigation, which can completely avoid the evaporation loss of water transmission and save water. Generally, it saves 30-50% water than the open channel system. It can also prevent soil salinization, swamping and cold leaching caused by channel leakage.

The pipeline friction coefficient is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.

The material has high oxygen index and self extinguishing property.

The linear expansion coefficient of the pipeline is small, 0.07mm / ℃, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and the anti freezing performance is excellent compared with the cast iron drainage pipe.
