GB/T 24721.3-2023 Highway Glass Fiber Reinforced Plastic Products Part 3: Pipes is a standard that specifies the requirements and test methods for glass fiber reinforced plastic (GRP) pipes used in highway applications.
This standard is applicable to GRP pipes made from polyester, epoxy, or other suitable resins, reinforced with continuous filament glass fiber. These pipes are commonly used in highway drainage systems, culverts, and other infrastructure projects.
The standard covers various aspects such as dimensions, materials, mechanical properties, testing, and inspection requirements for GRP pipes. It provides guidelines for the design, manufacturing, and installation of these pipes to ensure their durability, reliability, and long service life.
The mechanical properties of the GRP pipes, such as tensile strength, flexural strength, and impact resistance, are tested according to the specified procedures to ensure compliance with the standard requirements.
Furthermore, the standard also includes provisions for quality control, marking, and packaging of GRP pipes, promoting consistent product quality and facilitating proper identification and handling during transportation and installation.
In conclusion, GB/T 24721.3-2023 is an essential standard for the manufacturing and use of GRP pipes in highway construction. It ensures the quality and performance of these pipes, contributing to the overall safety and efficiency of highway infrastructure.
