FRP Flange

Product Introduction

FRP flange is specialized connection components used in fiberglass reinforced plastic (FRP) piping systems. They serve to join FRP pipes, valves, or other equipment, ensuring a tight, leak-proof, and corrosion-resistant connection. Produced using the hand lay-up method and high-quality resins such as epoxy, vinyl ester, or polyester, FRP flanges offer excellent strength-to-weight ratio, chemical resistance, and long service life.

FRP flanges can be customized to meet specific dimensional and pressure requirements, making them suitable for a wide range of applications. Commonly used in chemical processing, water and wastewater treatment, and flue gas desulfurization (FGD) systems, FRP flanges are an ideal solution for demanding environments that require lightweight, durable, and non-metallic piping connections.
