Johnson Screen and Wedge Wire Screen for Multiple Applications

Wedge Wire Screens--The Right Screen for Every Application

Details

For a wide range of industrial and process applications Saiptech manufactures a complete line of Wedge Wire industrial screens. The Wedge Wire screen products are constructed of a series of parallel "V" resistance welded cold drawn wire, cold wound welded on perpendicular support rods. The result is a smooth plug resistant screen surface that is very structurally sound. our WedgeWire industrial screens provide superior performance in numerous process industries including chemical, petrochemical, and water treatment.

 

• High wear resistance • High impact resistance • Larger open area • Self-supporting structure • Non-plugging slot design • Lower operation and maintenance cost

Our EM hybrid processing techniques give our screens several absolute comparati advantages, including: • High weld strength • Higher accuracy and consistency of wire gap • Lower surface roughness • Single piece cylinder construction (As opposed to welded patched cylinders) Axially-seamless cylinder construction
