Fiberglass Reinforced Plastic (FRP) Cable Protection Pipe – A pipe made from unsaturated polyester resin as the matrix, reinforced with continuous glass fiber and its fabrics, and formed through computer-controlled winding or pultrusion processes. FRP Cable Protection Pipes are highly utilized in cable laying, offering clear advantages such as high strength, corrosion resistance, and a smooth inner wall that does not scratch cables.
Product Features:
High strength, suitable for direct burial under the traffic lane, no need for concrete protective layer, can accelerate the construction progress.
Good tensile strength, capable of withstanding external heavy pressure and foundation settlement-induced damage.
Excellent electrical insulation, flame-retardant, and heat-resistant properties, capable of long-term use without deformation at high temperatures up to 130 degrees.
Corrosion-resistant with a long service life, it can withstand the erosion of various corrosive media such as acids, alkalis, salts, and organic solvents, with a lifespan up to 50 years.
The inner wall is smooth, preventing any damage to the cables. The rubber sealing ring facilitates easy installation and connection, and is adaptable to thermal expansion and contraction.
Low weight and volume, easy to be lifted by one person and installed by two, significantly reducing construction time and installation costs, while avoiding prolonged road excavation and disruptions to urban traffic flow.
Non-electrolytic corrosion, non-magnetic. Unlike steel pipes and other magnetic materials, it does not generate eddy currents that cause the cable to heat up and deteriorate.
Wide Application Range: The glass fiber reinforced plastic cable protection tube is suitable for use as a protective conduit for cable burial and laying, as well as in high-demand situations like cable crossing bridges, rivers, etc. By using a matching professional pipe support set, it can be configured into a multi-layer, multi-row multi-tube conduit arrangement.
Connection Method: Glass fiber reinforced plastic cable pipes mainly use "O" type sealing ring push-in connection, while flanges or bonding methods can also be adopted at special locations.
Application Fields: FRP cable protection pipes are suitable for protective conduits for power and communication cables in various environments. Especially in special conditions such as cables passing through traffic hubs, rivers, and bridges, they fully demonstrate their superior performance, including ease of installation and high strength. They are widely used in infrastructure construction fields such as power, communication, transportation, and civil aviation airports.
Structural Features:
(1) Offers excellent corrosion resistance; no need for cathodic protection or other corrosion prevention measures. Does not cause secondary pollution to water or other media. Long service life of the product.
(2) Lightweight, the pipe weighs only 1/4 of the same size and length of ductile iron pipes and 1/10 of concrete pipes. Easy for transportation, loading, and unloading, as well as installation.
(3) Longer pipe lengths reduce pipeline joints, accelerate installation speed, and enhance overall pipeline quality.
(4) The inner wall of the pipe is smooth, reducing flow resistance, increasing flow velocity, and lowering energy consumption. By using a smaller diameter pipe to convey the same volume of fluid, compared to pipes of the same specification, the flow rate can be increased by about 10%; it does not scale, and its flow rate does not decrease over long-term use. It also provides good protection for cables in turbulent and heavily corrosive environments.
