Corrosion Management

Initially all stainless steel tubular products were of seamless construction, but with improved metallurgy and welding process, the benefits of welded products diminished the use of seamless. Non-destructive testing can be used to allow a joint coefficient or welding factor for longitudinal welded tubes of 1.0 according to EN standards

Welded Stainless Steel Tubes & Pipes vs. Seamles

By optimizing the welding procedure followed by heat treatment and chemical cleaning (pickling) the Corrosion resistance of the weld also equals that of the base metal. Today, welded tubular products play a vital role in virtually every industrial segment supporting our daily lives, Stainless steel pipe and tubes have good to excellent corrosion resistance and high quality surface finish characteristics, and are for these reasons used in demanding applications such as food processing, pharmaceutical production, for the conveyance and processing of liquids, gas and semi-solids in solution. Weld tubes and pipes are also ideal, suitable for applications within the oil & gas, petrochemical. chemic.ai, energy, pulp & paper industries etc. This article detailing the import ant considerations in selecting tubular products was originally presented at the INOX 2010 — 10th Brazilian Stainless Steel Conference in Rio de Janeiro, Brazil.
