Wedge Wire Screen Pipe (Johnson Screen Tube)
DefinitionWedge wire screen pipe, also known as Johnson screen or profile wire screen tube, is a high‑efficiency cylindrical filtration element. It is made by welding V‑shaped (wedge) wires spirally around longitudinal support rods, forming precise, continuous linear slots.
Materials
- Stainless steel: 304, 304L, 316L, 321 (most common)
- Special alloys: Duplex steel, Hastelloy (for corrosive environments)
- Carbon steel/galvanized steel: For general‑purpose applications
Key Features
- Precise slot size: 0.05–10 mm, accurate filtration rating
- Non‑clogging design: V‑shaped slots widen inward, easy to backwash
- High open area: 30–60%, large flow capacity, low pressure drop
- Robust all‑welded structure: High mechanical strength, pressure resistance
- Corrosion & wear resistance: Long service life in harsh conditions
- Fully customizable: Diameter (25–1200 mm), length, slot size, end fittings
Working PrincipleFluid passes through the outer V‑wire slots into the pipe; solid particles are trapped on the outer surface. The wider‑inward slot profile prevents particle wedging and enables effective self‑cleaning/backwashing.
Main Applications
- Water wells: Sand control, groundwater extraction
- Oil & gas: Downhole sand control, produced water filtration
- Water treatment: Industrial & municipal water, wastewater, desalination
- Mining & mineral processing: Dewatering, slurry separation
- Chemical & food processing: Filtration of viscous fluids, solid‑liquid separation
Specifications (Customizable)
- Slot opening: 50 μm – 2 mm
- OD: 25–600 mm (up to 1200 mm)
- Length: Up to 4 m
- End connection: Plain, threaded, flanged, etc.
