From food to transport, from decoration to structural use, from the conduction of fluids to heat exchangers, stainless steel round tubes are used in every type of industrial use.

The measurements shown are not the only measures produced by welded pipes. Sectors such as petrochemical, food industry, press fitting, are sectors regulated by dedicated regulations, which follow millimetric measures different from those reported above and often the external diameters are expressed in inches and the thicknesses in the schedule, as for the seamless tubes.

Obtained through the bending of ribbons, the stainless steel round tubes can be welded using three main methods:

- TIG (without filler metal)

- HF (high frequency induction


The choice of the welding method to be used according to the field of use of the tube is made, avoiding the most expensive choice if for example of sections of a tube for ornamental use. The Laser technology guarantees very high quality levels but is currently not used much as the plants are very expensive. The most economical welding process is Hf, which, although having excellent quality because it affects almost nothing the geometric and structural characteristic of the pipe, is generally used for ornamental uses. For the petrochemical and food sector, Tig welded pipes are generally used, thanks also to the absence of the welding bead removed after the fusion of the strips of the strip.

The tubes can be supplied with the following external appearance: Raw, Brushed, Satin in grained, Polished only external, Polished inside and outside. Most often, the Satin tube is used for furniture. The polished tube, especially in Aisi 316, is used on boats for rails and ladders or even for balustrades or parapets. The internal and external Polished tube follows specific regulations as it is used most in the food sectors for the transport of fluids.

On request, the pipes can be produced in different lengths, as per customer's needs.
