    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, 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 tube for hot food fluids (10, 110), comprising:
    - an inner layer (11, 111) made of HNBR hydrogenated nitrile rubber,
    - one or more intermediate reinforcement layers (12, 112),
    - an outer covering layer (13, 113) made of elastomeric material, for example also made of HNBR hydrogenated nitrile rubber.
