Description

Technical Field

[0001] The utility model relates to a glass fiber repair pipe, specifically a continuously wound glass fiber reinforced plastic repair pipe. Background Art

[0002] There are generally three ways to repair damaged existing glass fiber reinforced plastic pipes: First, when the leak point is small and the surface is regular, the method of clamping can be used. This method does not require production suspension and the construction is simple and fast, but the applicable range is small. Second, when the surface is unevenly damaged, glass fiber cloth is wound and patched with a composite solution. During construction, it is necessary to completely empty, the environment is dry, and it is repeatedly wound and bonded with the composite solution and then allowed to set for 12 hours. However, it is easy to be damaged under high pressure after repair. Third, when the leak point is large, the pipe is cut and replaced. According to the damage situation, a certain length of pipeline is cut off, the two ends of the pipeline are sanded, and the pipeline is connected by the winding method. This repair method is prone to leak points at the connection of the pipeline and requires multiple repairs, resulting in poor repair effects and high repair costs. Therefore, a continuously wound glass fiber reinforced plastic repair pipe is proposed. Content of the Utility Model
