| titleOfInvention | COMPOSITE PIPE WITH DISTRIBUTED GAS BARRIER |
| abstract | The utility model relates to pipeline engineering, in particular to multilayer composite thermoplastic pipes with fiber reinforcement and barrier layers used in the oil, gas industry and hydrogen energy, used to transport gaseous and liquid substances, oil, gas, fluids, methanol, hydrogen, mixtures hydrogen with natural gas.n n n The problem is solved by the fact that a composite pipe with a distributed gas barrier, which consists of a multilayer inner pipe made of thermoplastic polymers, a composite material surrounding it, consisting of a thermoplastic polymer composite material and unidirectional continuous reinforcing fibers, and an outer polymer shell, in which the multilayer inner pipe , the composite material and the outer polymer shell are fused to each other by heating, characterized in that the composite material contains barrier layers (A) fused to the composite material by heating, the multilayer inner pipe contains barrier layers (B) cohesively bonded to the layers of the multilayer inner pipes, in which the barrier layers (A) and the barrier layers (B) consist of a polymer-matrix composite consisting of a thermoplastic polymer of the barrier layers, and a filler made of a layered material with a particle thickness of 1 to 900 nm and an aspect ratio of 50 to 18000, with volume fraction in the thermoplastic polymer of the barrier layer from 0.1 to 45%; while the barrier layers (A) include continuous unidirectional fibers in a volume fraction of 2 to 80%, which are surrounded on all sides by a polymer-matrix composite.n n n EFFECT: reduced gas permeability of high-pressure thermoplastic polymer-composite pipes, providing high resistance to delamination of high-pressure thermoplastic polymer-composite pipes with a non-metallic gas barrier. 18 w.p. f-ly, 1 ill. |
