Welded Tubes & Welded Steel Pipe
This is generally small bore/diameter steel tubing that has been produced by electric resistance welding (ERW) without annealing or drawing. Our selection of welded tube and welded steel tube includes hollow sections, black and galvanised gas/water pipe, scaffolding tube and large diameter pipe. 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. Large diameters (400-1,600mm) are made from plate which is welded in an ‘O’ shape before being mechanically or hydraulically expanded.
Spiral welded tube/pipe is also available.
