  1. E355 compliant with UNI EN 10297 – Circular-cross section steel welded tubes for general mechanical and engineering uses ;
  2. S235JR, S355J0H, S355J2H compliant with UNI EN 10210 – Hot finished structural hollow sections of non-alloy and fine grain steel for structural applications ;
  3. E470 compliant with UNI EN 10294 – Hollow bars for machining .

THE STEEL TUBES THAT WE SELL AND DISTRIBUTE

Tubes are fabricated during various production cycles that affect mechanical properties and surface finishing features:

  1. Hot rolled tubes for mechanical applications subdivide in turn in Hot rolled seamless tubes for mechanical applications, in this case the tolerances on the outside diameter and thickness are those stated in UNI EN 10297 standard reference and Hot rolled welded tubes for mechanical applications. They are obtained from coils and their ends are electro-welded; the seam is removed (scarfing). Dimensional tolerances are narrower than those of seamless tubes (+/- 0,5mm outside diameter, +/- 10% on thickness)
  2. Cold Drawn Tubes which are subdivided in Cold drawn weleded tubes for mechanical applications and Cold drawn seamless tubes for oleo-dynamic circuits and general use. Cold drawn weleded tubes for mechanical applications can be supplied according to different heat treatments as +AR (BK) Natural tube, + SR (BK+S) Stress relieved, + N (NBK) Normalized . Heat treatment entails tube bending and deformation. Dimensional tolerances are in the order of +/-0,05/0,10mm and +/-0,05/0,15mm on the outside diameter and on the inner one respectively. Cold drawn seamless tubes for oleo-dynamic circuits and general use are always supplied as Normalized (+N) in order to ensure a perfect degree of cold working. Dimensional tolerances are +/- 0,5mm on the outside diameter and +/-10% on thickness.

Interacciai SpA handles a wide range of hot rolled and cold worked Tubes.
