Baotong 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 ten characteristics: high ring stiffness, strong tensile strength, smooth inner wall, excellent thermal conductivity, high and low temperature resistance, high electrical insulation, strong flame retardancy, corrosion resistance and waterproof, easy to transport and install, safety and environmental protection.
①High ring-stiffness

⑤Smooth inner walls
⑦Excellent thermal conductivity property
⑨Corrosion and water resistance
②High-low temperature resistance
④High electric insulating property
⑥Strong flame resistance
⑧Easy transportation and installation
⑩Safe and Environmental-friendly

| Appearance | The conduit has even color; there is no crack on inner and outer surface, separated layers, pin holes, impurities, glue shortage area, bubbles and other defects; the inner and outer surfaces should be smooth and flat and should not have sags and crests. Two end surfaces of the conduits should flat without sharp edge and burrs. | Eyeballing |
