Continuous fiber reinforced thermoplastic pipeline and production method

Abstract

Belonging to the technical field of pipeline forming, the invention discloses a continuous fiber reinforced thermoplastic pipeline and a production method. The continuous fiber reinforced thermoplastic pipeline includes an inner pipe, the pipeline outer wall of the inner pipe is compounded with a reinforcing layer through an adhesive layer, the surface of the reinforcing layer is coated with an adhesive layer, and an outer protective layer is covered to the surface of the adhesive layer through hot melting extrusion. According to the invention, the process design is reasonable, the stress strength of the pipeline can be improved, and a one-step molding technology is adopted, so that the production procedures are reduced, the yield is increased while the production cost is reduced, and thelarge-scale popularization and application of the product are facilitated.

Description

technical field [0001] The invention discloses a continuous fiber-reinforced thermoplastic pipe and a production method, in particular to the technical field of pipe forming. Background technique [0002] In recent years, continuous fiber-reinforced thermoplastic pipes have been a hot research direction in the international pipeline field. Because of their obvious advantages, they can not only exert the high strength of fibers, withstand high pressure, but also maintain the good toughness and corrosion resistance of thermoplastics. It has a broad market in the application of high-pressure pipes such as oil delivery pipes and gas pipes. [0003] my country's reinforced fiber thermoplastic pipes have made great progress. At present, my country has been able to independently develop and produce steel mesh skeleton polyethylene composite pipes, which are widely used in the national economy. The uniformity of steel mesh skeleton meshes directly affects the performance of the pipe...

Problems solved by technology

[0003] my country's reinforced fiber thermoplastic pipes have made great progress. At present, my country has been able to independently develop and produce steel mesh skeleton polyethylene composite pipes, which are widely used in the national economy. The uniformity of steel mesh skeleton meshes directly affects the performance of the pipeline Pressure resistance value, where the skeleton mesh is dense, the pressure resistance value is higher, and the place where the skeleton mesh is sparse has a lower pressure resistance value, so the pressure resistance value of this type of pipeline is not high, and its lower pressure bearing capacity affects to a certain extent At the same time, the production of this kind of pipeline is more difficult and the cost is higher, which limits the application of this pipeline
