FRP pipe is consist of inner layer, Structural layer and outer layer. Its characteristics are:
- Lightweight, high strength and high stiffness, its density is 1.5-1.9, equals one fifth of steel pipe, one fourth of cast steel pipe and three fourth of pretensioned concrete pipe(PCP).
- Corrosion-resistant property. The Corrosion-resistant property of FRP pipe is mainly relied on the inner resin, and it can be selected based on the condition of the media.
- Good hydraulic property. The inner surface of the FRP pipe is very smooth, its friction coefficient (f) is 0.000915 after performed the relative testing, the water conservancy factor (c) can be kept within 145 and 150 during a long period.
- health property. For the pipe which be used for transporting the potable water, the food grade resin will be used. It has been approved by the relative national sanitary authority.
- Shock resistance. It doesn't occur delamination and cracking under the condition of deformation of 25%.
- Abrasive resistance. The inner surface is made of one kind of resin with good abrasive resistance, so it can improve the abrasive resistant property of the FRP pipe.
- Low temperature resistant property. There will not be cracking under the condition of -40ºC and the strength doesn't decline.
- It can be used for different kind of environment, such as beach, benthal, river, mountain area, marshland, desert and plain etc.

6.1 The section of the ditch
6.1.1 The surface of the ditch should be connected smoothly, and the wall of the ditch should be vertical.
6.1.2 The width of the ditch above the pipe only needs enough space to ram the backfill of the two sides of the pipe. If it is necessary can dig a hole in the coupling position, it means the width of the ditch need enlarge 2 meters, the length need enlarge 2 meters, the bottom of the ditch need decrease 1.5 meters, this hole should be filled up and rammed after backfill.
6.1.3 The depth of the ditch can be defined according to the following factors, such as the pre-designed device in pipeline, property, dimension of the pipe, the property of the soil, the static load and the dynamic load.
6.2 Steady ditch condition (see Fig. 5)

6.3 Unsteady ditch condition
These two ways of installation can be adopted if the unsteady ditch wall and the unsteady ditch bottom appear (see Fig.6 and Fig. 7).
