Longitudinally welded steel pipes are used in a variety of fields, including the construction of water and gas pipelines, the manufacture of equipment for diverse purposes, the installation of heating systems and the production of fittings and components for water or gas supply networks. The straight seam, formed by high-frequency or submerged-arc welding, provides predictable dimensional accuracy and consistent mechanical properties along the full length of the pipe.
