Starting from steel strips, produced by Acciaieria Arvedi, which guarantee constant mechanical characteristics and close wall thickness tolerances, ATA produces high frequency induction welded (HFI) precision tubes in conformance with standard EN 10305-3 and in accordance with customer specifications. These tubes, which have the most stringent prescriptions on dimensional tolerances are often processed with deep deformations and the obtained finished products are then frequently subjected to occasional loads or continuous fatigue stress. Industrial parts, machinery such as rolls, moving structures and crane parts are examples of their applications. ARVEDI Mother shell for cold drawing represent ATA’s core business where it is the leading European company and the only independent supplier of these products. These tubes can be produced as hot stretch-reduced or welded from black or pickled stripe, to standard EN10305-3, EN10210, EN 10296 or to customer specification; they are made in a wide range of steel grades and in the full size range of diameters from 17 to 355,6 mm and wall thicknesses from 1.5 to 16 mm. ARVEDI mother shell are suitable for cold drawing to obtain tubes with close tolerances and low roughness used in particular in the automotive sector and hydraulic and pneumatic industry.
