  • Multilayer tube, particularly for fluids
    Patent number: 11498321
    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.
    Type: Grant
    Filed: April 30, 2020
    Date of Patent: November 15, 2022
    Assignees: FLUORTUBING BV, TUBIGOMMA DEREGIBUS S.R.L.

  • Multilayer tube, particularly for chemical and food-related fluids
    Patent number: 11378206
    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.

  • MULTILAYER TUBE
    Publication number: 20210348702
    Abstract: 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.

  • MULTILAYER TUBE, PARTICULARLY FOR CHEMICAL AND FOOD-RELATED FLUIDS
    Publication number: 20200166159
    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.

  • MULTILAYER TUBE, PARTICULARLY FOR FLUIDS
    Publication number: 20170114929
    Abstract: 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.
