The technical advantages of UV curing methods

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.

Classification and Principles of Pipeline Curing Inspection Technology

By analyzing the distribution of the surface temperature field on the curing pipeline, the quality of the curing process can be assessed—this method is particularly suitable for materials like epoxy resins and polyurethane. When curing is uneven, differences in heat conduction create temperature variations, which can be detected with high precision using an infrared camera capable of identifying even 0.1°C differences (based on research data from *NDT&E International*, 2022). The primary advantage of this approach is its non-contact nature; however, it demands strict environmental temperature stability during the process.
