Abstract: A multilayer tube, particularly for fluids, includes a sheath made of fluorinated polymers which is located in an innermost layer, which is adapted to be in contact with a circulating fluid, and is constituted by coupling a first, nonconducting material to a second, black-pigmented material that is electrically at least antistatic in the form of one or more continuous strips. The sheath has a smooth internal surface and is reinforced with external layers that are predominantly made of rubber.

Abstract: A multilayer tube, particularly for chemical and food-related fluids, which includes, in succession from the inside outward a first layer constituted by a tubular sheath that is at least externally corrugated and which defines the duct for the fluid. The tube further includes at least one second layer, which has an inner layer, chosen from between a rubberized fabric and an elastomeric material with textile reinforcement, which is arranged on the first layer, and an outer covering which is arranged on the inner layer.

Abstract: A multilayer containment and protection tube for conduits, cables and the like, includes an inner layer made of polymeric material, which is electrically at least antistatic, with a smooth internal surface, which forms a duct for supporting conduits or cables. The tube further includes one or more intermediate layers of electrically at least antistatic reinforcement, an outer layer made of electrically at least antistatic polymeric material, and a covering and finishing layer, which is electrically at least antistatic.

Abstract: The machine for producing vulcanized rubber tubes comprises two mutually opposite head sections, each having a base that supports two spindles. At least a first one of the two head sections has motorized spindles. A corresponding tubular core is rotated constantly, during operation, between the mutually opposite spindles of the two head sections and is supported, along its span, by supporting elements that are fixed to a supporting frame interposed between the two head sections. The two motorized spindles connected to the first head section are each supported together with a respective drive unit on a first slider that is movably coupled to the corresponding base. The slider is inclined with respect to a horizontal plane such that its upper part is exposed frontally to the operator.
