Welded Pipe
Steel
This is made from hot rolled or cold reduced strip, sheet or plate. Small and medium diameters are produced in continuous, multiple-roll mills that progressively bend incoming, unheated strip into a circular cross-section prior to welding along the longitudinal seam. Tube may subsequently be cold-drawn through dies to achieve precise dimensions and finish. This is cheaper than the seamless process but welded tube generally has a lower mechanical and pressure performance.
