The invention provides a thermoplastic glass fiber-reinforced flexible pipe design method. The method comprises the following steps of: selecting a medium layer according to medium characteristics; obtaining performance parameters of the medium layer material; setting section parameters of a glass fiber-reinforced flexible pipe, wherein the section parameters comprise an inner pipe wall thickness,a reinforced layer number, a glass fiber belt thickness and a glass fiber belt winding angle; and detecting whether design mechanical performance of the glass fiber-reinforced flexible pipe satisfiesdesign requirements or not, and if the detection result is negative, repeating the third step until the design mechanical performance of the glass fiber-reinforced flexible pipe satisfies the designrequirements. According to the method, the section parameters, comprising the inner pipe wall thickness, the reinforced layer number, the glass fiber belt thickness and the glass fiber belt winding angle, of the glass fiber-reinforced flexible pipe are screened through detecting whether the design mechanical performance of the glass fiber-reinforced flexible pipe satisfies the design requirementsor not, so as to obtain the section parameters, satisfying the design requirements, of the glass fiber-reinforced flexible pipe, so that the application of the thermoplastic glass fiber-reinforced flexible pipe design method to production becomes possible.
Description
technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a design method for a thermoplastic glass fiber reinforced flexible pipe. Background technique [0002] The earliest use of flexible pipes in my country was in the field of marginal oilfield development, and later gradually developed into water injection pipelines and gas pipelines. At present, flexible pipes that can be used for oil transportation are still in the experimental stage. Most of the flexible pipes for oil transportation are foreign products. [0003] Several domestic universities have carried out relevant theoretical and experimental research on glass fiber reinforced flexible pipes. For example, Bai Yong and Wang Lizhong of Zhejiang University used the finite element software ABAQUS to analyze and study the cross-sectional properties of thermoplastic glass fiber reinforced flexible pipes, including Analytical solution analysis of cross-section propert...
