The invention relates to a fiber mesh tape-wound and reinforced composite pipe, a preparation process and a device, belonging to the technical field of forming processes of composite pipes. The composite pipe comprises an inner-layer core pipe and a post-coated layer, as well as a fiber mesh tape arranged between two layers, wherein the inner-layer core pipe is extruded by a core pipe extruding machine, the adhesive resin fiber mesh tape is heated through a post-heating box, and the composite pipe is finally obtained by traction through a post-traction machine, sizing through a vacuum spraying and sizing box and the like. According to the composite pipe disclosed by the invention, the technology is adopted, the preparation process is simple, the existing tape plastic covering treatment process and the composite pipe forming process are combined into a whole, the number of workers for production is reduced, and the degree of automation is improved; furthermore, the used device is a conventional device, and the cost is reduced; and in addition, adhesive resin is firstly coated on the outer surface of the core pipe, and the plain woven fiber mesh tape is further wounded, so that the interface problem in the pipe is effectively solved, the mechanical properties of the pipe are upgraded and the stability of the pipe during long-term use is also improved.
