The RPM pipe is composed of inner layer, wound layer, resin-mortar layer and exterior corrosion-resistant layer, its density is 1.7~2.1, equals one fifth of steel pipe, one fourth of cast steel pipe and three fourth of pretensioned concrete pipe. As the filament wound reinforced structure exists at the two sides of resin-mortar layer, and its fiber contedt is 70%, so it can meet the strength requirement of the pipeline. Else, as the resin-mortar layer is between the middle areas--lower stress area. so it has increased the stiffness meantine no any decrement to the strength of the pipe.

The corrosion-resistant property of RPM pipe is mainly relied on the inner resin, and be selected in accordance with the condition of the media. lt is adopted the reinforced rich resin layer by fiberglass, the resin content is 80%, it can ensure that the RPM pipe prevent corrosion and leakage.
The inner surface of the RPM pipe is very smooth, the roughness coefficient is very small. Not only the inner surface of new produced pipe is very smooth, but also it is same smooth as the beginning after has been used many years, and no seaweed and other aquatic derivative be adhered. The water conservancy factor(C) can be kept within 140 and 150 during a long period. After the relative testing, its friction factor(f) is 0.0009 15, it is smaller than the (f=0.00232) and the steel pipe (SP)(f=0.00 179). It can decrease the pressure head loss obviously, capacity above 20%. So when the conveying the increase conveying capacity 1S same, can adopt the RPM pipe with lower diameter, can save the investment of the project.
