Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for glass fiber reinforced plastics (GRP) jacking pipes used in trenchless construction. It is applied in the design, production, and quality verification of pipes for underground pipeline installation, such as sewage, drainage, and water supply systems, where pipes are jacked into place without open excavation. The standard ensures structural integrity, leak resistance, and durability under the specific mechanical and environmental stresses of jacking operations.
