ABSTRACT:
A plurality of like wedge bars are formed with a groove between two lands. The wedge bars are assembled into a cylindrical screen, with the grooves defining screening slots of a uniform width. The wedge bars may be electron beam welded or furnace brazed to support rings. Alternatively, the wedge bars may be held in place by slots in support rings and circumferential clamping applied by jack wedge assemblies. Multiple cylindrical segments may be connected together into a single screen cylinder by an ear and slot arrangement. The screen cylinder so formed may have slots of 0.004 inches or less in width, and may be formed of a wide range of wear and corrosion resistant materials.
