Mechanical tubes - Import export

As per the norm EN 10297 specifies the technical delivery conditions for seamless round steel tubes. The tubes for mechanical applications are mainly used in those processes in which turning and CNC machines are used. The wide size range available, with OD from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.

In linguistic usage occasionally the terms coil heaters, nozzle heating elements, hot runner heating elements, cable nozzle heaters are used. Our HotMicroCoil heating elements can be used in a wide variety of applications. Their high level of plasticity ideally suits them to the heating of hot runner nozzles and for accurately heating the contours of three-dimensional surfaces. Many of our customers order HotMicroCoil elements in their unformed state of mineral insualted cable heaters and perform the subsequent shaping work themselves, while others commission us to shape and fit the heating cable elements. A large number of ready-to-fit heating solutions are available for plastic injection nozzles with clamping mechanisms, housing bezel, reflection tube or heat conduction sleeve.

The round SEAMLESS tubes are hot rolled and satisfy both the requirements of the norm EN 10210 for structural applications and EN 10297-1 for mechanical applications. These steel tubes are fully killed and are suitable for structural applications but with the possibility to reach up to 100 mm w.t., which is impossible for welded tubes. These tubes are used for the manufacture of various kinds of construction components, above all where heavy wall thickness are required.

The wide range of product portfolio of coils with different tube diameters, tube patterns, fin profiles, materials and options allows us to customize our coils for any specific application and fluids: air heaters, air coolers, condensers and evaporators for HVAC and various industrial applications. Kelvion heat exchanger coils are manufactured with copper tubes and aluminum or copper fins. The fins are equipped with special profiles developed at our R&D department enhancing heat transfer and keeping pressure drop at a moderate level. The customized fin spacing is achieved by collars which also provide the contact between the fin block and the tubes. Mechanical expansion of the tubes guarantees a perfect bond between the fins and the tubes leading to maximum heat transfer between both fluids.
