Custom wedge wire cylinders do more than match an outside diameter and length. Slot opening, profile size, support spacing, flow direction, reinforcement, and end connections control retention, capacity, pressure resistance, cleaning, and service life. Define these points from the process medium and mechanical load before production.
How a Wedge Wire Cylinder Works
Wedge-Slot Geometry
A wedge wire screen cylinder joins continuous V-shaped profile wire to longitudinal or circumferential support rods. The narrow edge forms the working slot, while the passage widens behind the surface. This geometry limits wedging and supports backwashing or scraper cleaning. Jingzhou Metal adds rings, flanges, threads, reinforcement, or scraper interfaces to match the drawing.
Industrial Applications
Applications include water intake and wastewater screening, oil and gas sand control, mining slurry separation, resin retention, pulp screening, brewery filtration, screw presses, centrifuge baskets, and self-cleaning filters.
Design Parameters That Affect Performance
Slot Opening and Retention
Select the finished slot from particle size, solids concentration, particle shape, deformability, allowable carryover, and cleaning method. A nominal value alone cannot protect performance. State the target opening, permitted minimum and maximum values, and inspection method on the drawing.
Open Area and Rigidity
Open area affects capacity and pressure loss, but maximum open area does not always give the best cylinder. Wide support spacing or a small profile can reduce stiffness. Calculate effective open area after deducting end rings, reinforcement, frames, and blocked installation zones.
Typical Custom Parameters
The table summarizes common options. Jingzhou Metal confirms the final range after reviewing the drawing, medium, pressure, and load.
| Parameter | Typical Option or Range |
| Material | 304, 304L, 316, 316L; duplex, 904L, or other alloys by project |
| Outside diameter | 25.4-1,200 mm typical custom range |
| Slot opening | 0.02-20 mm typical custom range |
| Filtration range | 15-800 micrometers for selected screen configurations |
| Profile wire | 0.5 x 1.0 mm to 5 x 10 mm |
| Profile tolerance | Up to +/-0.01 mm where the profile specification allows |
| Flow direction | Outside-to-inside or inside-to-outside |
| End and finish options | Rings, flanges, threads, welded ends; polish, passivate, or electropolish |
Note: These are reference ranges, not universal design limits.
Flow Direction and Structural Load
Outside-to-Inside Flow
Outside-to-inside flow keeps solids on the external surface and suits intake screens, external scrapers, and many resin systems. Collapse resistance often controls this design.
Inside-to-Outside Flow
Inside-to-outside flow suits selected screw presses and self-cleaning units, where the inner surface may face abrasion or scraper contact. Review operating and blocked pressure, pressure reversal, vibration, temperature, abrasive media, and rotation together. Diameter, length, profile size, support spacing, reinforcement, roundness, straightness, and runout must work as one structure.
Material and Surface Options
Stainless Steel Grade Selection
Jingzhou Metal supplies 304 and 304L for general water and industrial duties. Buyers often choose 316 or 316L for chloride-bearing water, sanitary service, or more corrosive media. Duplex grades, 904L, and other alloys support harsher chemical or high-strength requirements.
Finish and Roughness
Specify roughness separately from surface treatment. We can deburr, mechanically polish, pickle and passivate, or electropolish a stainless steel wedge wire cylinder. State an Ra value when the process requires a measurable finish.
Manufacturing and Inspection
Two Drawing, Two Annealing
We form working wire in-house through drawing, annealing, shaped rolling, a second annealing stage where required, and final drawing or calibration. This “two drawing, two annealing” route controls section geometry and surface consistency. We then resistance-weld the profile wire to support rods while forming the cylinder.
Finished-Cylinder Inspection
Our team verifies alloy grade by spectrometer, monitors wire consistency with infrared equipment, measures profiles with one- and two-dimensional projectors, and tests tensile properties. Finished checks cover slot distribution, diameter, length, roundness, straightness, connections, and weld condition. We can include agreed drawings and inspection records.
Custom Manufacturing Support from Jingzhou Metal
Jingzhou Metal is a source manufacturer, not a trading company. We have produced stainless steel wire since 2009 and operate three production bases covering about 18,000 square meters. In-house forming, mold preparation, machining, and inspection support drawing-based OEM/ODM work, replacements, and new profiles.
We accept custom drawings, design for actual operating conditions, and support small-batch prototypes. New-product development normally takes 7-15 days. Final lead time depends on material, dimensions, quantity, welding, and inspection. Our export experience also supports packaging, documents, and shipment.
FAQ
What information does Jingzhou Metal need to quote a custom wedge wire cylinder?
Send the medium, particle range, flow rate, temperature, operating and blocked pressure, flow direction, slot, diameter, length, connection, finish, quantity, and drawing. We can also review a replacement sample.
Which stainless steel grades suit wedge wire screen cylinders?
304 and 304L cover many general applications. 316 and 316L improve resistance in chloride-bearing and sanitary environments. Duplex, 904L, and other alloys suit aggressive service after we review chemistry, temperature, strength, and welding.
Can Jingzhou Metal make OEM wedge wire cylinders from drawings?
Yes. We customize slot, profile wire, support rod, diameter, length, flow direction, reinforcement, flange, thread, and finish. We also support small-batch samples for wedge wire screen tubes and Johnson screen cylinders.
What lead time should buyers expect for custom wedge wire cylinders?
New-product development typically takes 7-15 days. Production and delivery depend on material availability, tooling, quantity, welding complexity, inspection documents, and destination. We confirm the schedule after drawing approval.
