  • longitudinally welded tubes

    longitudinally welded tubes

    Longitudinally welded tubes are manufactured from sheet steel drawn from a coil(hot-rolled strip usually 2.75–5 mm thick and 65–300 mm wide). The diameter is determined by the width of the sheet; the correct width is slit at the factory and then formed to create a tube. Rollers/formers shape the ...
