Thick-walled tubes - Import export

On request, we supply ball caster rails / ball transfer units rails adapted to your individual requirements. We usually use rectangular section tubes with 2-4mm thick walls. The tubes are galvanised in the standard procedure, but can also be supplied with powder-coated surfaces in different RAL colours. Ball caster spacing patterns can be carried out in accordance with the collar size of the ball casters used. We supply profile lengths of up to maximum 6,000 mm. The ball casters / ball units are mounted by means of press fitting and are easily replaceable. So you’d like to “get something special rolling”, but have questions about it!? Please don’t hesitate to contact us in person or to use our contact form – we’re always happy to advise you!

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.

If required, we can supply capillaries and tubes with predetermined break points. For this purpose, the component is notched at the required breaking location. If the component is then subjected to a bending force, it will break at the notched point. To prevent unintended breakage, we recommend using medium or thick-walled tubes and capillaries.

We manufacture reagent and centrifuge tubes in standard sizes and also with special dimensions and versions from soda glass, borosilicate glass, neutral glass, and quartz glass – optionally with or without flanged rim. All our tubes have a flame burnished rim and can be supplied with a rounded, flat or pointed conical bottom. We are able to process tubes with diameters up to 40 mm, and lengths up to about 500 mm – also thick-walled tubes. Special reagent micro tubes We are able to manufacture reagent micro tubes with rounded bottoms, i.e. with very small dimensions. For example, soda glass tubes with rounded bottom, flame burnished rim, 3 mm diameter, and a length of 20 mm. Test tubes with notch for thermal processes These special test tubes were developed to enable ventilation of the tube’s interior during a thermal process. The notch prevents complete closure and thus an over pressure.
