Wedge Wire Screen is welded by profile V-wire and support wires,also called Johnson screen.It has large filter area because of slot opening,vee wire structure is easy for automatic back washing and avoid pipe blocking.The pressure will be reduced when water flows in greater filter area,avoid the grains of sand flow in the wedge wire tube in the high pressure conditions,so extend the pipe's life.
Types: Flat wedge wire screen,Sieve bend screen,Helical spiral steel pipe,Precipitation filter pipe,wells filter pipe,Wire wrapped screen,Oil well sand control screen, Johnson screen tube,wedge wire basket,etc.
Feature High mechanical strength can bear large pressure drop Equal slots for filtering can form equally distributed filter cake The wedge type slot can improve back flushing and regeration performance It has resistant to pressure temperature aging corrusion can be applied for different kinds of fluid.
Slot size: 0.1 - 6.0 mm,also can be customized as request
Length: max 6.0 meters
Diameter: 25 - 1200 mm
