A kind of production method of glass steel pipe

Abstract

The invention provides a method for producing FRP pipes. The operation is completed by the cooperation of the shell, the gluing device, the conveying guide wheel, the roll barrel group, the lower pressing frame, the gravity roller group, the driving device and the electric slider. Solve the need to apply glue to the glass fiber filaments before winding them. The existing gluing process usually passes through the glue liquid surface when the glass fiber filaments are conveyed to achieve the effect of gluing. However, the amount of gluing is often not controlled, and After gluing, the glass fiber filaments are entangled together, and the glass fiber filaments are not arranged neatly, which leads to different thicknesses of the winding layers during the later winding, which affects the quality of the FRP pipe. The layer may be wound loosely, which will lead to problems such as rough surface of the formed FRP pipe.

Description

technical field [0001] The invention relates to the field of FRP pipeline production, in particular to a production method of FRP pipeline. Background technique [0002] FRP pipe is a light, high-strength, corrosion-resistant non-metallic pipe. FRP pipe has the advantages of excellent corrosion resistance, long service life, light weight, convenient transportation and loading and unloading, and is often used in petroleum, chemical and drainage industries. During the production process of FRP pipes, the glass fiber filaments need to be neatly arranged and then wound on the outer wall of the inner lining of the pipe. However, the following problems are often encountered before the glass fiber filaments are wound: [0003] 1. Glass fiber filaments need to be glued before winding. The existing gluing process usually passes through the glue liquid surface when the glass fiber filaments are conveyed to achieve the effect of gluing. However, the amount of gluing is often not contro...

Problems solved by technology

[0003] 1. Glass fiber filaments need to be glued before winding. The existing gluing process usually passes through the glue liquid surface when the glass fiber filaments are conveyed to achieve the effect of gluing. However, the amount of gluing is often not controlled. Moreover, the glass fiber filaments after gluing are entangled together, and the arrangement of the glass fiber filaments is not neat, which leads to different thicknesses of the winding layers during the later winding, which affects the quality of the FRP pipe.

[0004] 2. During the winding process, the glass fiber wire may be loosely wound on the inner lining of the pipe, resulting in a rough surface of the formed FRP pipe
