Product Description Product Description1.The property and advantage of RPM pipe    As the RPM pipe is accompanied with sand in its structure,compared with the pure RPM pipe,it not only has property of lightweight and high strength,but also possess high stiffness as the buried pipe and low cost. So it is welcomed from its presence. The usage in conveying water or other fluid is more and more. The relative information reported that 160 thousand kilometers long RPM pipe had been installed in America during the middle period of 1990s. in Europe,the length of new laid large and middle diameter RPM pipe for conveying water and sewage accounted for 30-50% of total installed length. In Japan,this kind of RPM pipe account for a certain share,its total installed length had exceeded the aggregate of steel pipe and concrete pipe. And in MidEast area. almost all the pipes for conveying water, sewage and desalinated seawater are RPM pipe.2. Characteristics of RPM pipe2.1 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 meantime no any decrement to the strength of the pipe.2.2 Corrosion-resistant propertyThe corrosion-resistant property of RPM pipe is mainly relied on the inner resin, and be selected in accordance with the con-dition 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.2.3 Good hydraulic property The inner surface of the RPM pipe is very smooth; the rough-ness coefficient is very small. Not only the inner surface of new pro-duced pipe is very smooth,but also it is same smooth as the begin-ning 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 0.000915, it is smaller than the (f-0.00232) and the steel pipe (SP)(f=0.00179).It can decrease the pressure head loss obviously;increase the conveying capacity above 20%.So when the conveying capacity is same, can adopt the RPM pipe with lower diameter, can save the investment of the project. The conveying ca-pacity comparison can see the following Table 1 and Diagram2.4 Health property of RPM pipeThe main material of RPM pipe is unsaturated resin and fiberglass, are formed by a specified procedure. So its inner surface is very smooth and the stiffness is above Barcol 40 HBa ,the unsaturated resin itself was passed the certification by the relative national sanitary authority and the RPM pipe also has been verified by the relative national sanitary authority. So the RPM pipecan be com-pletely used in the conveying drinking water and it has above 20 years practical example.2.5 Anti-shocking propertySince the RPM pipe is between the stiff pipes and flexible pipe, so its Anti-shocking property is good, it will deform under the action of strong foreign force, but it will not bring its breakdown and deformation because it doesn't bring delamination and cracking under the condition of deformation is 25%.2.6 Abrasive resistanceThe inner surface of RPM pipe is added abrasion resistant filling, so it can improve the abrasive resistant property of the pipe, and can pro-long the life of the product.2.7 Low temperature resistant propertyThere will not be cracking under the condition of -40-Cand the strength of the RPM pipe doesn't decline.2.8 Compliance with the environmentThe RPM pipe is applicable for the different kind of environment, such as beach, bottom of the sea, river.mountain area, marshland, desert and plain, etc. It has the following characteristics: fast installation, convenient transportation and long life, etc.Detailed PhotosProduct ParametersParameter of RPM PipeFRP PIPE, GRP PIPE, FRP MOTAR PIPE, FRP DUCTING, FRP FGD PIPE, FRP CHIMNEY, FRP JACKING PIPE, FRP INSULATION PIPE CertificationsCompany ProfileHengshui Jiubo Composites Co., Ltd. is professional manufacturer of FRP Pipe, FRP storage tank, FRP cooling tower, FRP molded products, FRP pultruded products and relative FRP production machines & technology.
