Problems solved by technology

Among them, the inner layer, the middle layer and the outer layer are all provided with an adhesive layer, and the composite pipe is bonded to each other; the bending radius of the pipe is too large after the composite pipe with an integrated structure is formed, which is difficult for the storage, transportation, and maintenance of the pipe. Inconvenience was caused during the laying and installation process; in addition, in the selection of adhesives, the specifications of composite pipes with different structures are inconsistent, and they are basically solvent-based chemical preparations, which have caused great harm to human health and safety in the production environment. harm

Abstract

The invention belongs to the technical field of a plastic composite pipe, and discloses a coiled plastic composite pipe reinforced with fibre. The technical scheme includes that an inner tube layer is made of polymer materials, the outer wall of the inner tube layer is wound or braided a wear-resistant fibrous layer constituted by polyester industrial fibers, aramid fibers and glass fibers, the outer surface of the fibrous layer is coated with a modified polymer corrosion protection layer, and the inner tube layer, the fibrous layer and the protective layer composite into one integral structure. The coiled plastic composite pipe reinforced with fibre has the advantages of small bending radius, high pressure resistance and high temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of plastic composite pipes, in particular to a coilable reinforced plastic composite pipe used in petroleum, chemical, ocean and other fields. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for energy in various industries has increased significantly, especially the dependence on oil and gas resources. The existing oil and gas industry production is used to transport sewage, polymer injection and strong corrosive media (such as containing Hydrogen sulfide, CL - , CO 3 Natural gas, etc.) pipelines generally use steel pipes or glass steel pipes. The defects of steel pipes are heavy weight, easy corrosion, and short service life. The defects of glass steel pipes are poor creep resistance, difficult maintenance, and cannot be reused after scrapping, which is easy to cause environmental pollution. [0003] In view of the current problems, various c...
