<p>Pipe for transferring abrasive material, such as concrete, comprising at least a tubular body (11) defining an external surface (17) and an internal surface (16) through which the abrasive material is suitable to flow, wherein the tubular body (11) is made of fiber-reinforced composite material and comprises a plurality of fibers (21, 22) overlapping each other and drowned in a polymer material (20) to define the thickness (S) of the tubular body (11). The polymer material (20) in turn also defines a uniform layer (23), substantially continuous, in correspondence with the internal surface (16) of the tubular body (11). Moreover, the polymer material (20) has high elasticity and low hardness, and is chosen from a group comprising at least polypropylene, polyamide, thermoplastic elastomers, polyurethane resins, epoxy resins.</p> |
