摘要： 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.

摘要： 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.

摘要： A multilayer tube, particularly for fluids is provided with an internally hollow shape and includes a co-extruded sheath made of fluorinated polymers such as FEP, MFA, PFA, ECTFE and PTFE, located in the innermost layer. The sheath is constituted by an internal substrate made of non-pigmented virgin material and by an external substrate made of pigmented material.

摘要： A multilayer tube which includes, in succession from inside outward: an inner layer 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 for the inner layer and which follows its corrugated shape, and a helix wound on the protective layer and positioned on a bottom of the troughs, and an outer layer, in which the helix is embedded.

摘要： 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.

摘要： A tube for hot food fluids includes an inner layer made of hydrogenated nitrile rubber (HNBR), one or more intermediate layers, and an outer covering layer made of elastomeric material. For example, the outer covering layer could be made of HNBR. One or more of the intermediate reinforcement layers include at least one textile reinforcement layer that is resistant to high temperatures. One or more of the intermediate reinforcement layers may further include two layers of textile reinforcement resistant to high temperatures, with the interposition of a filler layer made of elastomeric material.
