| titleOfInvention | COMPOSITE PIPE WITH DISTRIBUTED BARRIER PROPERTIES |
| abstract | The utility model relates to pipeline technology, in particular to multilayer composite thermoplastic pipes with fiber reinforcement and barrier layers manufactured by extrusion or molding and / or winding methods used in the oil and gas industry, used for transporting gaseous and liquid substances, when installing gas and oil wells, and for repair and tripping operations.n n n The problem is solved by the fact that a composite pipe with distributed barrier properties, which consists of an inner tube made of a thermoplastic polymer, a surrounding composite material consisting of a thermoplastic polymer composite material and unidirectional continuous reinforcing fibers, and an outer polymer shell, in which the inner tube, a composite the material and the outer polymer shell are smoothly fused with each other by heating, characterized in that the composite material contains at least one barrier layer of a polymer-inorganic composite fused with the composite material by heating and consisting of a thermoplastic polymer of a barrier layer, and homogeneously dispersed in thermoplastic polymer of a barrier layer of a filler from a laminated material with a particle size from 1 nm to 800 nm and an aspect ratio from 50 to 6000, with a volume fraction of a barrier layer in the thermoplastic polymer from 0.2% to 40%.n n n EFFECT: reduced gas permeability and high resistance to delamination of high-pressure thermoplastic polymer-composite pipes. 15 p.p. f-ly, 1 dwg. |
