Introduction

GB/T 24721.2-2023 Roadway Glass Fiber Reinforced Plastic Products Part 2: Pipe Boxes is a national standard in China that specifies the requirements for glass fiber reinforced plastic (GRP) pipe boxes used in highways. This standard ensures that GRP pipe boxes meet the necessary quality and performance criteria to withstand various environmental conditions, such as temperature changes, water exposure, and mechanical stress. It covers aspects such as dimensions, appearance, physical properties, and mechanical properties of the pipe boxes. The GRP pipe boxes specified in this standard offer several advantages for roadway applications. Firstly, they are lightweight yet strong, providing excellent structural integrity without adding excessive weight to the infrastructure. This makes them easy to transport, install, and maintain. Secondly, GRP pipe boxes have a high resistance to corrosion, moisture, and chemicals, ensuring their long-term durability. They are also resistant to UV radiation, ensuring their stability and color retention over time. Furthermore, these pipe boxes have excellent electrical insulation properties, making them safe for use in various electrical applications. They are also non-conductive and non-magnetic, reducing the risk of interference with sensitive equipment. Overall, GB/T 24721.2-2023 Roadway Glass Fiber Reinforced Plastic Products Part 2: Pipe Boxes provides a comprehensive standard for the production and use of GRP pipe boxes in the construction and maintenance of highways, ensuring their quality, durability, and safety.
