BWFRP power and communication pipelines are made of high performance fiber composites and epoxy resin. They are composed of braided layer, middle layer and outer layer. They are interlaced by high performance fiber longitudinal and transverse braiding and extrusion. It has the characteristics of high ring stiffness, high tensile strength, high and low temperature resistance, high electrical insulation, superior thermal conductivity, corrosion resistance/water resistance, flame retardant, safety and environmental protection, light pipe and so on. Products with incomparable advantages of traditional pipes, by the majority of customers and the market favor!
