chemical composition. A wide range of grades and thicknesses are held in stock to ensure that customer requirements can be met quickly. Slitting of coil feedstock is carried out in-house on coils up to 30 tonnes, followed by welding with laser welding lines, and subsequent pickling to remove every trace of ferrous and oxidising contamination, which could be detrimental to corrosion resistance. Ilta Inox has the capability to pickle tubes in lengths up to 18m. Tubes produced by Ilta Inox are subjected to a constant on-line dimensional check (laser OD checking), as well as continuous destructive tests, including flaring, flattening, reverse bending and expansion, in order to evaluate the integrity of the weld area. In addition, in order to guarantee the integrity of the whole tube wall, 100 per cent of production is eddy current tested off-line.

With its modern production facilities, Ilta Inox can guarantee products that meet stringent market requirements, and that are certified by important international testing organisations. The company has been certified according to ISO 9002:1994 since 1994, and according to ISO 9001:2000 since 2000, and is also certified to AD 2000-Merkblatt-TRD 100 97/23/EC (PED), and has ISO 14001 environmental certification. Raw material is purchased only from suppliers who are ISO 9000 certified. Before processing, the company undertakes a 100 per cent check on incoming material using a portable spectrometer, followed by further laboratory analysis to verify the exact
