Technical Conditions:
Fully Annealed, High quality, Burst free Stainless Steel tubes.
An outside diameter range from 4mm OD to 25mm OD
A wall Thickness range from 0.36mm to 1.5mm
starting from a single production line for electro welded stainless steel tubes with small diameters and wall thickness,with a yearly production of 2,5 million meters in three different diameters (7,50 - 9,50 - 10,00 mm).
 
 
Outside Diameter and wall thickness ranging from 0,36mm to 1,50mm thick , in addition to a wider range of diameters and wall thickness, we can also supply bright heat-treated tubes in controlled atmosphere, either in coil, fixed or cut to length tubes up to 20 meters.
We produce in compliance with the international standards foreseen for the different types of product and different applications. Up to 300 bar pressure testing is carried out on 100% of the heat-treated tubes supplied in coils.
Alloys normally used range from austenitic, AISI 300 series, to refractory high nickel content alloys (alloy 800 - 825 - 840, alloy 600 - 601).

28 million meters per year on 12 production lines, 40 different tube diameters ranging from 4,00mm to 25.00 mm
