Stainless steel johson screen is widely used throughout the world for water, oil & gas wells, and is the dominant screen type used in the water well industry. The wedge v wire screen tube is made up of rods and profile wire. The rod can be round wire, triangular wire or trapezoid wire. The profile wire is triangular wire (V-shaped wire). This type of slot screen tube has a structure and high open area, as well as accurate slot dimension. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings. Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be non-clogging, narrowest at the outer face and widen inwardly. Wire Wrap Screen can be used in both Gravel Pack and Stand Alone Screen (direct retention) applications. Screens are available in a range of sizes and specifications, including outside diameter, material type, the geometry and dimension of the screen slots, and so on.

Application of Stainless steel Johnson screen

Our stainless steel cylinders can be used in food processing, waste water filtration, pulp and paper as well as mineral processing applications. Wedge wire or profile screen half cylinders can be added to an auger or screw press to separate solids from liquids in food, waste water, minerals and industrial grit/chips from coolant.

Features & Benefits of Stainless steel Johnson screen

1) A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.
2) A “V”shaped profile wire which avoids clogging and ensures an uninterrupted flow.
3) A uniform and efficient well development due to the continuous slot opening.
4) Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.
5) Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
