High resistance to corrosion, maintenance-free Due to resistance to acid, alkali, salt, seawater, sewage, corrosive soil and various chemical fluids and smooth internal wall, no incrustation and microorganism may occur in the pipe, so the pipe can keep clean for a long term use and be free of maintenance.

High strength The pipe has an excellent strength, maximum allowable working pressure is up to 6.4MPa, and design safety factor is more than 6.

水力特性佳 管道的內壁非常光滑,新管道的Hazen-Wll liams粗糙系數C值為150一165,在同樣的 管徑條件下,本管道的流量比鋼管要大36%。

Customized design The pipe can be designed flexibly according to any set of appropriate technical parameters to meet the demand and requirements of customers as far as possible.

Rigid and flexible According to engineering requirement, a sand layer is added at the intermediate layer where the bending stress is small to enhance the rigidity, so any requirements on rigidity can be met. In case that the pipe is subject to an overload (e.g. lorry) in a short time, the pipe may bear the load through its own elastic deformation and recover its original shape automatically after the load disappears.

Long service life The pipe body is made of very stable high polymer material and its breakdown pressure is designed with 6 times working pressure to ensure 50-year service life.
