Glass fiber-lined pipes exhibit significantly higher strength in tension, bending, and other mechanical properties. Currently, most glass fiber repair materials available on the market achieve an elastic modulus of 12,000 MPa and a tensile strength exceeding 95 MPa, ensuring that structurally repaired systems can last for at least 50 years.

　　(1) Glass fiber-lined pipes exhibit significantly higher strength in tension, bending, and other mechanical properties. Currently, most glass fiber repair materials available on the market achieve an elastic modulus of 12,000 MPa and a tensile strength exceeding 95 MPa. Moreover, structurally repaired pipelines can last for at least 50 years under normal operating conditions.
　　(2) UV-cured repair technology has become the most widely used repair method both domestically and internationally, thanks to its rapid application—typically requiring only 3 to 5 hours to complete a pipeline section around 30 meters long with a diameter of DN800 or smaller—minimal site occupation, thin repair layers, reduced water flow loss, high elastic modulus, straightforward installation, and low environmental impact.
