Production Process of FRP Pipe:
The length-fixed winding process is controlled by computer. Manufacture the liner on the mandrel as the same process of fiber glass winding pipe, then after the resin became hardened, make the structure layer by winding according to the designed linearity and thickness, and add the mixture of mortar and resin into the structure layer, finally, wind the outer protection layer.
The pipe is consisted of inner liner, interface, structural layer, and outer surface layer.
Inner liner corrosive resistance layer, Surfaces exposed to the chemical environment shall be resin-rich and reinforced with a 10 or 20 mil thick chemical surfacing mat (E- glass).
Interface layer is leakage proof layer, it be reinforced by minimum of three layers of 1.5 oz chopped strand mat.
Structural layer will be reinforced by continuous strand fiberglass roving and shall maintain a resin content of 20-40%. It is reinforcement for the inner lining layer and interface, resisting the foreign load to the pipe body and ensures the strength and stiffness of the pipe body.
The exterior surface shall consist of a chopped strand glass over which a resin-rich coating shall be applied.
Characteristics of FRP Pipe:
1) Lightweight, high strength and high stiffness
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.
2) Corrosion-resistant property
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. It 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.
3) Good hydraulic property
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=0.0O 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. The conveying capacity comparison can see the following Table and Diagram.
