Aluminium pipes - Import export

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.

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

custom printer accessories for machining.

These are the pipes made from aluminum,which as the connector to connect the parts.

RK tube connectors – the flexible alternative to welded connections The clampable tube connectors from RK Rose+Krieger are a cost-efficient solution for the positive and ready detachable connection of a diverse variety of systems – without the need for drilling and welding. Depending on the field of application and the expected load, RK Rose+Krieger offers tube connectors made of plastic (Light Clamps), aluminium (Solid Clamps) or stainless steel (Robust Clamps). The Solid Clamps tube connector system also includes the RK monitor mounting for the fixation and ergonomic adjustment of monitors and touch screens used in industrial applications. Say goodbye to welding – that could be the motto of the clampable RK tube connectors The simple assembly technology of the clamping elements eliminates the need for time-consuming and cost-intensive drilling and welding work.

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.

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.

Seamless tube elbows made of aluminum for welding.

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.

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.

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.

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.

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.
