The most popular process for large diameter pipe uses a longitudinal seam weld. Red Earth Steel's Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp. The defects that occur in spiral welded pipe are mainly those associated with the SAW weld, and are similar in nature to those for longitudinally welded SAW pipe. End Of Pipes: Plain Ends, Threaded Ends, Bevel Ends Plain Ends: Manufactured Pipes by Red Earth Steel Plain ended pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges. Threaded Ends: Implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings. Beveled Ends: Beveled Ends implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe. Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm). COPYRIGHT © 2019 DORIS
