In today's industrial and construction fields, finding an ideal pipeline material with both high strength and corrosion resistance has become a key requirement for many engineering projects. With its excellent physical and chemical properties, FRP composite pipes have been widely used in many industries such as water supply and drainage systems, petrochemicals, and marine engineering, and have gradually become the preferred solution to replace traditional metal pipes.FRP composite pipes are composed of continuous glass fiber reinforced resin matrix. This unique composite structure gives the pipe excellent mechanical strength and durability. Compared with traditional steel pipes or cast iron pipes, FRP composite pipes are not only light in weight, easy to carry and install, but also have higher tensile strength and compressive resistance, and can withstand large external loads without deformation or rupture. Especially in areas with complex geological conditions or frequent earthquakes, its good toughness and elastic modulus help improve the seismic performance of the entire pipe network system.Corrosion resistance is a highlight of FRP composite pipes. Since unsaturated polyester resin or epoxy resin is used as the matrix material, this type of pipe has strong resistance to chemical media such as acid, alkali, and salt, and will not rust or age even if exposed to harsh environments for a long time. Therefore, it is particularly suitable for use in chemical plants, sewage treatment plants, and water supply projects in coastal areas, effectively solving the problem of traditional metal pipes being susceptible to corrosion, extending the service life of the pipes and reducing maintenance costs.In addition to the above advantages, FRP composite pipes also exhibit excellent inner wall smoothness. Its surface roughness coefficient is as low as 0.0085, which is much lower than that of ordinary steel pipes or concrete pipes, which means that the fluid has less resistance when flowing inside it and has higher transmission efficiency. In addition, the lower friction coefficient also helps to reduce scaling and sediment accumulation, keep the pipeline unobstructed for a long time, reduce the need for regular cleaning, and further improve economic benefits.From an environmental protection perspective, FRP composite pipes meet the current requirements of green buildings and sustainable development. There is no need to consume a lot of energy during the production process, and no harmful gas emissions are generated; the product itself can be recycled and reused, reducing resource waste and environmental pollution. For enterprises that pay attention to environmental protection, choosing FRP composite pipes is not only a guarantee of engineering quality, but also a social responsibility.In practical applications, FRP composite pipes can be customized according to different working conditions. Whether it is the diameter size, wall thickness specification or connection method (such as socket type, flange type), it can be flexibly adjusted according to specific needs. For example, in high-pressure water pipeline projects, thickened wall layers can be selected to increase pressure bearing capacity; in occasions where frequent disassembly and maintenance are required, it is recommended to use convenient and fast quick connectors to improve construction convenience and later maintenance efficiency.It is worth mentioning that with the advancement of technology, the research and development of FRP composite pipes has made many breakthroughs in recent years. The application of new reinforcement materials has further improved the mechanical properties of the pipeline; nano-modification technology has improved the weather resistance and UV resistance of the resin matrix, making it suitable for long-term outdoor exposure environments. These innovative achievements have laid a solid foundation for broadening the application scope of FRP composite pipes.With its many advantages such as high strength, corrosion resistance, low resistance, environmental friendliness and high customization, FRP composite pipes are gradually replacing traditional pipeline materials and playing an important role in many industries. Whether in new construction projects or the renovation of old pipelines, it has demonstrated incomparable value and made positive contributions to promoting the development of infrastructure construction in a more efficient, economical and green direction.
