    摘要： A multilayer tube (10, 110), particularly for fluids, which comprises a sheath (11, 111) made of fluorinated polymers which is located in the innermost layer, which is adapted to be in contact with a circulating fluid, and which is constituted by coupling a first, nonconducting material (14, 114) to a second, black-pigmented material that is electrically at least antistatic in the form of one or more continuous strips (15, 115).
    The sheath (11, 111) has a smooth internal surface (30, 130) that is reinforced with external layers that are predominantly made of rubber.

    摘要： A multilayer tube (10) which comprises, in succession from the inside outward:
    - an inner layer (11) constituted by a tubular sheath which defines a passage duct for a fluid and is corrugated at least externally, thus defining troughs,
    - a protective layer (12) for the inner layer (11) and which follows its corrugated shape,
    - a helix (14) wound on the protective layer (12) and positioned on a bottom of the troughs,
    - an outer layer (15), in which the helix (14) is embedded.

    摘要： A connecting portion of a multilayer tube, particularly for chemical and food-related fluids, the multilayer tube comprising, in succession from the inside outward:
    - a first layer (11) constituted by a tubular sheath that is externally corrugated in a screw-like manner and which defines the duct for the fluid,
    - at least one second layer (12), which is shaped internally like a female thread and is coupled mechanically to the first layer through the interaction of the threading,
    and the connecting portion (13) being characterized in that it comprises:
    - a tubular element (14) which is internally and externally threaded and is inserted at a corresponding end (15) between the first layer (11) and the at least one second layer (12) via screwing.

    摘要： A multilayer tube (10), particularly for industrial systems for the production and/or treatment of chemical compounds and the like, in fluid form, comprising a plurality of layers (11), of which at least one internal layer (12), which forms the duct for the fluid, an electrically conducting layer (13) which is external to the internal layer (12), and a protection and finishing layer (14) of the electrically conducting layer (13) which it covers, forming the outer surface (15) of the multilayer tube (10).
    The protection and finishing layer (14) has a matrix (16) made of electrically insulating material that is penetrated by electrically conducting bridges (17), the bridges (17) being discrete, mutually electrically insulated from the matrix (16) and scattered substantially uniformly within it. Furthermore, the bridges (17) are in electrical contact with the electrically conducting layer (13) and facing the external surface (15) so as to form an electrical connection between the electrically conducting layer (13) and the outside of the multilayer tube (10).
