Abstract

The invention discloses a production process for a continuous fiber reinforced composite pipe. The production process comprises the following process steps: molding of an inner pipe, winding and covering of an auxiliary layer, winding of a reinforcing layer, winding of a functional layer, molding of an anti-abrasion layer, winding of an axial tensile layer, winding of a functional isolation layerand molding of an outer protective layer. Compared with a conventional production process for the continuous fiber reinforced composite pipe, the production process provided by the invention has the following advantages: the inner pipe is wound with industrial filaments, so the creep resistance and the internal pressure resistance of the inner pipe are enhanced; when the pressure is low, the winding layer number of the reinforcing layer is reduced; the requirements on angular tolerance and clearance during winding of the reinforcing layer are reduced; the controllability of a pressure pipelinein production is enhanced; the raw material cost of a product is reduced; and the axial loading capacity of a pipe material is enhanced, and the pipe material can be generally used for marine pipelines, jumper pipelines and pressure pipelines in dynamic and non-dynamic environments.

Description

technical field [0001] The invention relates to the field of pressure pipelines for long-distance and short-distance transportation of fluid media such as oil, gas and water, and in particular to a production process for continuous fiber-reinforced composite material pipes. Background technique [0002] Continuously reinforced continuous fiber reinforced composite pipe is a new type of high performance composite pipe. The permeable industrial filament layer, the pressure-enhancing layer wound on the outer surface of the industrial filament, is designed to meet the needs of industrialization and continuous production to reduce the temperature sensitivity of the outer protective layer during processing, and reduce the coldness of the plastic during processing. The functional layer with thermal shrinkage difference is wound on the outer surface of the reinforcement layer, and the cladding layer to prevent the mutual friction between the reinforcement material and the tensile ...
