TH22621B - Piping for high pressure fluids - Google Patents

Abstract

A tube consisting of an inner core with multiple surface layers (1), in which the outer layer is made with a They are polyamides or EVOHs to enable them to effectively block and reinforce the exterior to withstand high pressure. Such outer reinforcement will consist of at least A fiber-reinforced structure (4), one layer placed around the core (1), a covering outer layer (7), and at least one binder (3, 5) to adhere to the reinforced structure ( 4) to the inner core (1) where the binder is selected from the polyurethane compounds. Or polyamide as a hot melt adhesive And the heat-adapted polyester

Claims (1)
