Pipes and tubes- aluminium - Import export

Air flow routing tubes are designed to channel different kinds of air to appropriate destinations. If you have a specialized vehicle and need superior flexibility in your air duct tubing, these products lead the industry. CARADUCT® flexible tubes are multi-layer, grooved tubes that are wound from a combination of aluminum and paper layers. They possess a particularly high crushing strength and have very good insulation properties. Through high flexibility and small bending radii, they offer good space usage, particularly when laying out in corners. Dükerrohr is a twin flexible tube distinguished by a particularly high insulation effectiveness to reduce temperature drops in the warm air ducting. Since it is installed outside of the vehicle, it carries additional protection against water and oil splashes.

CORMIFLEX® tubes are folded spiral-seam pipes made of high-grade steel precision strip. Reaching up to 350°C, their high temperature resistance is predominantly used for exhaust gas routing in passenger car, utility vehicle, RV and marine heating units. CORMIFLEX® PLUS bears additional resistance against corrosion due to salt and other aggressive agents.

The light weight and pliability of aluminum make it easy to work with and can streamline installation. In addition to the weight advantage and ductility, aluminum provides a complete barrier to light, moisture and magnetic waves. Impermeable to all gases including oxygen, aluminum also provides superior fireproofing capabilities for both industrial and residential construction. Aluminum insulation offers good noise reduction properties along with resistance to corrosion and heat. Not only does this improve interior environments, it also increases product life and efficiency. These proven characteristics continue to make aluminum the leader in insulation and the preferred choice for all types of building and construction.

Novelis is the global leader in rolled aluminum products and aluminum beverage can recycling. Our technical competence and innovation have made us a development partner chosen by leading companies from the automotive, building, printing and packaging industries, among others. With its customer orientation and strong industrial performance, Novelis plays a crucial part in shaping products for the future. The aluminium content means that there is only slight thermal length variation, just like with metal tubes. In addition, the tubes become completely oxygen-impermeable, which is indispensable when connecting radiators, for example. Using state-of-art production facilities and experienced specialists, Novelis ensures top quality in the manufacture of its products – across the entire production process, from casting and processing the ingots via hot and cold rolling, to packaging.

Heat protection sleeves and mats extend our expertise in protective aluminum flexible tubing to other shapes and uses. Layers of aluminum foil are combined with fiberglass for products that can withstand temperatures up to 750°C.

Heat protection tubes are made by layering several kinds of aluminum alloy foil and other materials, such as fiberglass and plastic with corrugations. The excellent reflectivity of the aluminum alloy on the external surface reflects radiant heat, and its insulating power additionally serves to protect the aluminum flexible tube’s content from heat sources. These products have great flexibility but high dimensional stability, and they can be compressed or extended as required. They can also be fastened or mounted easily by crimping the end fittings.

Our OHLER product line is specifically designed for use in automobiles and caravans. Novelis is one of the leading suppliers of flexible tubes and hoses for the automotive sector with products used for heat protection, air ducts, exhaust pipes, thermal insulation and energy absorption.

By creating specialized aluminum alloys, pioneering new treatments and combining aluminum components with other materials such as paper, plastic and fiberglass, Novelis has become the global quality leader for the transportation manufacturing industry. We have created a range of transportation manufacturing products that provide insulation against heat, sound and gases, high strength so components remain effective under pressure, and superior flexibility for a full range of designs and implementations. Key Novelis aluminum components include heat exchangers, heat protection mats and sleeves, energy absorption elements, hoses, silencers and flexible tubes, including heat protection tubes, air ducts and exhaust pipes. Novelis is a leading supplier of light-gauge, narrow-slit aluminum fin stock (bare and clad) and brazing sheet used in the production of heat exchangers.

We produce aluminium pipe bends with the following characteristics and product specifications: DIN EN 573-3, 755-1, /-2 /-9

Suction lances / suction tubes can be delivered in different diameters right from stock. We also can manufacture according to your drawing and/or sketch or sample. material: stainless steel AISI 304 or aluminium AlMgSi 0.5 F22 in all common tube dimension 40.0 / 50.0 and 60.3 mm right from stock special versions can be realised at short notice and for short delivery]

Depending on the application, tubes may require subsequent drawing following the extrusion process. Examples of this are: a requirement for a high degree of dimensional control and/or the need for tight tolerances, where the final outside diameter and/or wall thickness of the extruded tubes can only be achieved by subsequent cold drawing, where the final mechanical properties for non-heat treatable alloys are to be achieved by strain hardening (drawing) or where special requirements exist for the microstructure of the tubes.

In the aluminium industry, the porthole extrusion process is the standard method for the production of extruded tubes and profiles. The process is limited to a number of aluminium alloys. However, most of the commercially available medium strength aluminium alloys such as EN AW-6060 or EN AW-6082 can be extruded by porthole extrusion.

Aluminiumwerk Unna AG is specialised in the production of Aluminium tubes. The Aluminium tubes are extruded on site using two possible methods. These are either Seamless extrusion or Porthole extrusion. It is quite simple to distinguish between the two extrusion methods. In seamless extrusion, a mandrel is positioned and fixed inside the extrusion die, creating the inner contour of the tube. In porthole extrusion, the mandrel is fixed and is supported by a number of integral bridges affixed to the outer portion of the extrusion die.

Seamless aluminium tubes can be ordered in all commercially available aluminium alloys in addition to high strength aluminium alloys which are required for more demanding applications. ALUnna has a number of extrusion presses equipped with mandrel piercing capability. This allows us to extrude a large range of extruded tubular dimensions from a number of different billet diameters. The size range for seamless extruded tubes ranges from 17 mm to 300 mm in diameter.

The noise levels in pipe and rod raising systems can be very high. A chute lined with secutex pipe modules ensures that noise levels are reduced and that surfaces are protected. The secutex material with inset perforated plates is particularly wearresistant and cushions the movement of pipes and rods very well. The cast sections are attached using drilled attachment holes. Segment sizes and joins are manufactured according to client requests.
