Wedge Wire Filter Tube – Stainless Steel Slot Tube for Industrial Filtration
Wedge wire filter tube, also known as wedge wire screen tube, slot tube, or Johnson screen tube, is a high-performance filtration component widely used in industrial separation systems. It is manufactured by wrapping V-shaped (wedge) profile wires around support rods and welding them together to form a continuous slot structure.
This unique design creates precise slot openings that widen inward, effectively preventing clogging and ensuring smooth flow. Compared with traditional perforated pipes or mesh tubes, wedge wire filter tubes offer higher open area, better filtration efficiency, and longer service life.
At WireMeshi, we produce high-quality stainless steel wedge wire filter tubes tailored for industries such as water treatment, oil & gas, mining, food processing, and chemical filtration.
