Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a nondestructive detection device for the winding quality of a reinforcement layer of a flexible composite pipe. Background Art

[0002] The reinforcement layer of the flexible composite pipe is an important component of the flexible composite pipe, and is usually made of high-performance materials, such as glass fiber, carbon fiber or aramid fiber. These materials have the characteristics of high strength, high modulus and light weight, which can improve the mechanical properties and durability of the flexible composite pipe. Usually, these high-performance materials are wound on the surface of the flexible composite pipe. In order to detect whether the reinforcement layer of the flexible composite pipe is tightly wound, the staff usually needs to observe and detect it with the naked eye. This detection method is inefficient. Therefore, we propose a non-destructive detection device for the winding quality of the reinforcement layer of the flexible composite pipe to solve the above problems. Utility Model Content
