Abstract: Tube for conveying fluids comprising a plurality of concentric layers (2), an inner layer (3) constituting a conduit (3a) for a fluid to be conveyed, and at least an outer layer (5) for protection and reinforcement mounted externally to the inner layer (3), in which the inner layer (3) is pigmented and mainly made of a fluoridated polymer chosen between MFA and PFA. The tube (1) further comprises at least an adhesive (6) interposed between the outer layer (5) and the inner layer (3). The present invention also relates to a method for the production of said tube (1), comprising the following steps: subjecting an outer surface (4) of the inner layer (3) to a cementing process, subsequently applying an adhesive (6) to the outer surface (4), and coating the outer surface (4) with at least an outer layer (5). The cementing process takes place by at least partial defluorisation of the outer surface (4) of the inner layer (3).

Abstract: An antistatic hose for conveying fluids with at least one conductive layer (2) comprising a first, conductive material (3) and a second, non-conductive material (4). The first, conductive material (3) forms a basic matrix and medium sized blocks (5) of the second, non-conductive material (4) are inserted in the basic matrix of first, conductive material (3). The first, conductive material (3) forms a continuous conductive path (6) extending along the entire length of the hose (1). The second material (4) is distributed in the matrix of first material (3) in an uneven and irregular way. The first material (3) preferably comprises a thermoplastic material to which particles of a conductive material have been added, whilst the second material (4) is thermoplastic.
