Wedge Wire V Shape Johnson Screen Filter Pipe

8" wedge wire pipe filter,vaious filteration,water well screen


Wedge wire screen cylinder are welded by profile V-wire and support wires , it also called Johnson screen . The features are high ratio filter area because of big opening , vee wire structure are easy for automatic backwashing and avoid pipe blocking . The pressure will reduce when water flow in for greater filter area , avoid the grains of sand flow in the wedge wire tube in the high pressure conditions , so make the pipe life longer . Between the same length ,diameter and slot size ,wedge wire pipe is thrice than brige filter pipes.
Material : Low carbon steel wire , AISI 304 , AISI 304L , AISI 316 , AISI316L , high quality stainless steel wire.
Application : With the high-precision,our wedge wire as filter elements used in water treatment industry,oil filtration , paper making , refine sugar , we have inside perforated metel and reverse wedge wire tube outside filter.

1. The V-shape section plane of Wedge wire screen pipe (Johnson screens) creates the continuous slot , which can avoid blockage and make sure of the unimpeded water.
2. The consecutive slot of Wedge wire screen pipe (Johnson screens) have wider open area , and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure , so it can control sand better , which can increase the water yield and prolong service time of the well.
3. Wire and support rods are all-welded , which makes the Wedge wire screen pipe (Johnson screens) more robust and longer life.
4. The longitudinal support rods and the continuous slot make the Wedge wire screen pipe (Johnson screens) have more excellent pressure-resistant performance.
5. Specifications and end connections of Wedge wire screen pipe (Johnson screens) can be fabricated according to customers’ requirements.

The welded continuous slot wedge wire screens are made up of rods and wire.

The rod can be round wire, triangular wire or trapezoid wire. The wire is triangular wire (V-shaped wire).

Water well screens have a structure and high open area, as well as accurate slot dimension.

At the same time, water well screens have heat-resisting, anti-corrosive, good machine capability, long service life,
safety and reliability and so on characteristics. It can be used in many kinds of medium filtering.
