Stainless Steel Johnson Slotted Wedge Wire Tube
High Strength Continuous Slot Filter Tube for Industrial Filtration
Stainless Steel Johnson Slotted Wedge Wire Screen Tubes are manufactured by welding V-shaped profile wires onto support rods to create a continuous slot opening structure.
The unique wedge wire design provides:
-High open area
-Excellent flow performance
-Low pressure drop
-Anti-clogging capability
-High mechanical strength
Suitable for water filtration, well screens, sand control, industrial separation and liquid-solid filtration applications.
Custom slot size, diameter, length and material are available according to customer requirements.
Key Advantages
Continuous Slot Design
The V-shaped wire profile creates a smooth inner surface that helps prevent particles from becoming trapped.
Benefits:
✔ Reduced clogging
✔ Easy cleaning
✔ Stable filtration performance
High Open Area
Compared with traditional perforated tubes, wedge wire screens provide a higher open area for improved flow efficiency.
Strong & Durable Structure
Manufactured with stainless steel profile wire and support rods for excellent mechanical strength.
Custom Manufacturing
Available according to:
-Diameter
-Slot opening
-Length
-Wire profile
-Support rod design
