Glass fiber reinforced plastic pipeline production method

Abstract

The invention provides a glass fiber reinforced plastic pipeline production method. The glass fiber reinforced plastic pipeline production method is characterized in that a shell, a gluing device, conveying guide wheels, a coiled material barrel set, a downward pressing frame, a gravity roller set, a driving device and an electric sliding block cooperate with one another to complete the operation.The glass fiber reinforced plastic pipeline production method can solve the problems as follows, glass fiber filaments need to be glued before winding, according to the existing gluing process, usually the glass fiber filaments penetrate through a glue liquid surface when being conveyed so that the effect of gluing can be achieved, but the gluing amount often can not be controlled, the glued glass fiber filaments are often tangled up, the glass fiber filaments are not orderly arranged to cause different thickness of winding layers generated in the later winding process, so that the quality ofa glass fiber reinforced plastic pipeline is influenced, and in the winding process, the glass fiber filaments likely wind loosely around a lining layer of the pipeline, so that the surface of the formed glass fiber reinforced plastic pipeline is rough.

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
