GB/T 46199-2025
ActiveDuctile iron pipes for trenchless application
非开挖铺设用球墨铸铁管
Application Summary AI generated
This standard specifies the technical requirements, dimensions, and testing methods for ductile iron pipes specifically designed for trenchless installation methods, such as horizontal directional drilling and pipe jacking. It is applied in the construction of underground fluid transportation systems, including water supply, sewage, and gas pipelines, where open-cut excavation is impractical or undesirable. The standard ensures the pipes possess the necessary mechanical strength, joint integrity, and corrosion resistance to withstand the stresses of trenchless installation and long-term service.
