GFRP lining involves the installation of layers of fiberglass fabric impregnated with a polymer resin onto the surfaces of existing structures. The resin is typically a thermosetting polymer such as polyester, vinyl ester, or epoxy, which cures to form a durable and chemically resistant coating.

GFRP LINING
Features
FRP linings offer a range of benefits that make them highly effective for protecting and reinforcing various surfaces in industrial settings. Their excellent corrosion resistance makes them ideal for safeguarding metal and concrete surfaces from degradation due to corrosive chemicals, acids, and salts. The polymer resin in FRP linings provides robust chemical resistance, ensuring compatibility with a wide array of acids, alkalis, solvents, and hydrocarbons commonly found in industrial environments. Beyond corrosion protection, FRP linings also enhance structural integrity by reinforcing weakened or deteriorated structures, thereby extending their lifespan. These linings can be applied seamlessly to complex geometries and irregular surfaces, ensuring uniform coverage and preventing leaks and infiltration. Customization options allow for tailoring the linings to specific application needs, such as varying thickness, resin types, and reinforcement materials for optimal performance under different conditions. Depending on the chosen resin system, FRP linings can also offer high-temperature resistance, making them suitable for high-heat applications. Additionally, they can be formulated for abrasion resistance, protecting surfaces from wear and erosion caused by abrasive materials or high-velocity flow. Once installed, FRP linings require minimal maintenance, with routine inspections and occasional cleaning typically sufficient to maintain their performance.
Applications
FRP linings are extensively utilized across various industries due to their superior protective properties. In chemical processing plants, they safeguard tanks, vessels, and piping systems from corrosion and chemical attacks by aggressive substances used in industrial processes. Wastewater treatment facilities rely on FRP linings to protect concrete structures such as clarifiers, digesters, and effluent channels from corrosion and degradation caused by sewage and wastewater exposure. The pulp and paper industry uses these linings to shield equipment and infrastructure from the corrosive effects of chemicals involved in pulping, bleaching, and papermaking processes. In mining and metals refining operations, FRP linings protect tanks, vats, and process equipment from corrosion and chemical attacks by acids, alkalis, and metal-bearing solutions. The oil and gas production sector employs FRP linings to protect storage tanks, pipelines, and processing equipment from corrosion and chemical damage caused by hydrocarbons and corrosive fluids. Finally, power generation facilities, including fossil fuel power plants and nuclear reactors, use FRP linings to protect concrete containment structures, cooling towers, and process equipment from corrosion and chemical attacks.
