Abstract

The invention discloses a production process of FRP pipe, which is characterized in that it comprises the following steps: a) preparation of the inner lining layer of FRP pipe: spraying wear-resistant gel coat on the surface of FRP mandrel; b) winding process: wrapping the FRP pipe through winding equipment Glass fibers impregnated with unsaturated polyester resin are reciprocally wound onto the inner lining; c) curing process; d) preparation of the outer protective layer. The production process of the glass fiber reinforced plastic pipe provided by the invention makes the produced glass pipe have higher strength and rigidity.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic pipe manufacturing devices, and in particular relates to a glass fiber reinforced plastic pipe production process. Background technique [0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is a glass fiber with resin matrix weight wound layer by layer on a rotating core mold according to the process requirements. [0003] The existing glass pipe production process not only has a complicated operation process, but also produces products with poor strength and rigidity. SUMMARY OF THE INVENTION [0004] In order to overcome the deficiencies of the prior art, the present invention provides a glass fiber reinforced plastic pipe production process with high product rigidity and high strength. [0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: a production process for glass fib...
