3-inch 76mm ID Fiberglass Core FRP Tube

3-inch 76mm ID fiberglass core FRP tube producted by Hongkai Plastic are high-performance pipes manufactured through composite processes using glass fiber as the reinforcing material and synthetic resin as the matrix material. They feature lightweight construction, high strength, corrosion resistance, high-temperature tolerance, and superior insulation properties. These tubes are widely used in applications such as film winding, metal foil processing, and the electronics industry.

FRP core tubes demonstrate exceptional material properties, combining lightweight yet high strength with corrosion resistance, high-temperature tolerance, electrical insulation, and high precision. With a density only 1/4 to 1/5 that of steel, it boasts an exceptionally high specific strength, achieving a circumferential tensile strength exceeding 300 MPa. Its mechanical strength rivals or even surpasses ordinary carbon steel. Combined with its lightweight nature, it significantly facilitates handling and installation, effectively reducing transportation and construction costs. The resin matrix endows it with exceptional chemical corrosion resistance, effortlessly withstanding exposure to acids, alkalis, salts, and various organic solvents. Its service life typically exceeds 50 years, eliminating the need for additional internal linings or external coatings even in demanding environments like chemical processing and wastewater treatment. Regarding temperature adaptability, the standard operating range spans -40°C to 80°C. With specialized formulations, it can withstand temperatures up to 200°C, ensuring stable performance in high-heat conditions. As a non-magnetic material, it exhibits no eddy current losses, making it ideal for protecting power cables. Its low thermal conductivity also serves as an effective thermal insulator. Moreover, FRP core tubes feature high processing precision and superior surface finish. This not only significantly improves material utilization but also effectively prevents material damage caused by tube deformation.

4-inch 76mm ID fiberglass core FRP tube demonstrate powerful application advantages across multiple industries due to their outstanding comprehensive performance. In the field of film winding, they are extensively used for PET, PE, PI films, vapor-deposited films, labels, stickers, optical films, lithium battery separators, and other winding operations. Their high precision and exceptional surface finish perfectly meet the stringent quality requirements for “surface smoothness” and “straightness” demanded by high-end films, ensuring industry-leading winding quality. In metal foil processing, it effectively resists deformation during the winding of copper foil, aluminum foil, and other metal foils, preventing damage or wrinkling to ensure the integrity and stability of metal foil processing. In the electronics industry, FRP core tubes serve as packaging and transport solutions for electronic components. Their superior insulation properties act as a reliable shield, isolating components from static electricity and electromagnetic interference to ensure safety and stability during transit. Furthermore, in paper product winding, fiberglass rollers, and other applications, their wear-resistant and corrosion-resistant properties significantly extend equipment lifespan, reduce maintenance costs for enterprises, and provide robust, reliable support for production operations across various industries.

Hongkai Plastic's 3-inch 76mm ID fiberglass core FRP tube deliver powerful momentum for efficient production and quality assurance across diverse industries through their versatile adaptability and exceptional performance. Whether it's film winding demanding ultimate quality, metal foil processing requiring extreme stability, or protecting precision electronic components, these tubes handle every task with ease.
