In industrial liquid-solid separation, efficiency, durability, and low maintenance are paramount. Wedge Wire Cylinders (also known as slot tubes or profile wire screen cylinders) have become the benchmark solution for high-performance continuous filtration across chemical, water treatment, paper, and food processing industries.
What is a Wedge Wire Cylinder?
A Wedge Wire Cylinder is a cylindrical filtering element manufactured by wrapping triangular-shaped stainless steel profile wires continuously around internal or external support rods. The contact points are automatically resistance-welded to create a precise, highly durable structure with continuous slot openings.
Unlike traditional mesh or perforated plates, the V-shaped profile wire creates a two-point contact slot structure that naturally prevents clogging and reduces downtime.
Technical Specifications
We offer tailored manufacturing to meet exact operational requirements:
* Materials: Stainless Steel 304, 304L, 316, 316L, 2205 Duplex, Hastelloy, Titanium.
* Slot Sizes (Precision): From 20 microns up to 3.0 mm.
* Outer Diameter (OD): 25mm to 1200mm (custom diameters available).
* Cylinder Length: Up to 6000mm continuous section.
* Filter Direction / Flow Configuration:
FITO (Flow In-To-Out): Smooth internal surface, ideal for internal scraping or backwashing.
FOTI (Flow Out-To-In): Smooth outer surface, ideal for external filtration systems.
* Surface Profiles: Surface wire can run longitudinally (axial) or radially (transverse).
Key Advantages & Operational Benefits
1. Non-Clogging V-Wire Design: The narrowest opening is at the outer face, widening inward. Particles passing through the slot will not get trapped.
2. High Mechanical Strength: Solid resistance welding provides high differential pressure tolerance and burst resistance.
3. Low Pressure Drop & High Flow Rate: Continuous slot design maximizes open area compared to standard woven wire mesh.
4. Scraper & Backwash Compatibility: The smooth surface allows mechanical scraper blades or automated backwash systems to easily clear debris without wear on the filter media.
Major Industrial Applications
* Water & Wastewater Treatment: Intake screen cylinders, automated self-cleaning filters, resin traps, and municipal treatment systems.
* Food & Beverage Processing: Starch extraction, juice straining, sugar syrup clarification, and vegetable oil filtration.
* **Pulp & Paper:** Pressure screen baskets, fiber recovery, and dewatering cylinders.
* **Petrochemical & Mining:** Catalyst retention baskets, oilwell screening, slurry separation, and liquid-solid centrifuges.
