2507 Johnson type 89mm Continuous slot screen

2507 Johnson type 89mm Continuous slot screen 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.

Use:Wedge wire screen pipe for filter can be used as below:

1. Well sand control filter

2. Widely used in vairous kinds of medium filtering
3. As the fitting using in the water-treating equipment ( the environment protection; the sea water transforms into the industrial water and life use water desalination treatment; running water treatment; softening treatment;
4. The petroleum industry: the petroleum product terminal filters and the chemical acid; the alkali liquid filters, the ethyl alcohol;
5. The organic solution recycling filter

Advantages:
1. Screens with high open area are more suitable for the construction of high-quality water wells and gas wells.
2. Low cost operation.
3. Reduce the abrasion of the pump.
4. Extend the life span of wells, low-carbon, Galvanized or stainless steel construction.
