Wedge wire Johnson screen filter tube, also called round slot tube. It is made of stainless steel wire, which is the most popular type because of outstanding chemical stability and corrosion resistance.
Wedge wire filter tube, also called round slot tube. It is made of stainless steel wire, which is the most popular type because of outstanding chemical stability and corrosion resistance.
The wedge wire screen tube is composed of working profile and support profile. It is produced on an automotive machine. The support profiles is placed on the suit position of the machine, during the surface profiles are spirally wounding, the support profiles are welded onto the surface profiles.
Materials: SS 304, SS 316.
Maximum differential pressure: 300 psi.
Maximum temperature: Synthetic seals 500 °F / NPT 1500 °F.
Length: 10", 20", 30", 40" and customized types
Connection type: threads.
Bottom type: flat or taper.
The uniform filtration seams and the high precision guarantee an effective retention of the filter medium.
Wedge wire screens have a larger flow area than other screens.
The small gaps between the wedge wires form a smooth wedge-shaped cross-section with no dead space, good clogging resistance and easy backwashing (blow washing).
High mechanical strength, can withstand high pressure drop.
Made of high-quality stainless steel wire (SUS304, 316L), with strong corrosion resistance, high temperature resistance, fully adaptable to a variety of harsh environments
Adapt to different forms of fluid direction, with high strength, large flow rate, high pressure resistance performance
Maintaining stable filtration precision, repeatable and reusable, reliable work.
Wedge wire filters are used as primary filters with high flow rates and differential pressures in various water treatment fields such as boiler water, petrochemical water, paper water, ship ballast water, etc.
Wedge wire candle filters can be used as pre-coated candle wedge wire screens (vertical filtration elements, beer candle filters), diatomaceous earth alluvial filters/candle pre-coated filters for clarifying beer.

Details
Flow Direction
The direction of the flow is determined by the position of the surface profiles in replation to the support bar. Wedge wire filter are either flow-out-to-in(FOTI) or Flow-in-to-out(FITO).
FOTI
FITO
Test
1. It has high mechanical strength, can bear large pressure drop;
2. It has equal slots for filtering, can form equally distributed filter cake, easy to clean for reusing;
3. The wedge type slot can improve backflushing and regeneration performance;
4. It has resistance for pressure, temperature, aging, corrosion, can be applied for different kinds of fluid.
