A reverse wedge wire screen is often made to fit a specific filtration system rather than used as a standard replacement part. The required diameter, slot opening, wire arrangement, material, and end connection can change from one project to another.
For buyers, this means the first step is not simply finding a screen with the right dimensions. The screen also has to match the flow direction, solids, operating pressure, cleaning method, and surrounding equipment.
A custom reverse wedge wire screen is especially useful when the system requires inside-to-outside filtration. In this design, fluid enters the center of the cylindrical screen and passes outward through the continuous slots. The filtering surface is on the inside, while the outer support structure helps the screen hold its shape under pressure.
Xinlu’s Inverted Screen Pipe is one related product type for inside-out filtration. For custom projects, however, buyers should define the required wire layout and flow direction clearly because different reverse screen designs may use different wire arrangements.
A good screen specification starts with the process it will handle.
Before confirming dimensions, buyers should understand what fluid will pass through the screen, what solids need to be retained, and how much flow the system must handle. These details affect the slot size, open area, wire dimensions, and overall screen strength.
For example, a 0.6 mm slot may work well for one process but may be too large or too restrictive for another. Hard mineral particles behave differently from soft solids, fibers, resin beads, or sticky deposits. Flow rate and pressure can also change how particles behave at the screen surface.
Inside-to-outside flow should also be confirmed at the beginning. In a reverse screen, the untreated fluid enters the center and moves outward through the slots. Solids remain on the internal working surface while the filtered liquid collects outside the screen.
This flow path can work well in compact filter housings, process vessels, media-retention systems, and other equipment where the feed enters through a central connection.
The larger wedge wire screen range includes different shapes and structures for industrial filtration, but a custom screen should always be matched to the actual process rather than selected by product name alone.
A screen needs enough open area to handle the required flow without creating excessive pressure loss.
Open area depends on several parts of the design. Slot width is important, but screen diameter, active length, profile-wire size, and support-wire spacing also affect how much liquid can pass through the element.
As solids collect on the inner surface, the available flow area becomes smaller and the pressure difference across the screen increases. The screen therefore needs enough mechanical strength to handle both normal operation and temporary pressure increases before cleaning.
For continuous industrial use, buyers should provide the normal flow rate, operating pressure, and expected maximum differential pressure. This gives the manufacturer a better basis for checking whether the proposed wire and support structure is suitable.
The wire arrangement is one of the most important parts of a custom reverse wedge wire screen.
In the two reference designs, the profile wires run axially along the inside of the cylinder. Circumferential support wires are welded around the outside. The internal profile wires form the filtration surface, while the external supports keep the cylindrical structure stable.
This arrangement supports radial inside-to-outside flow.
The profile wire in both examples measures 1 × 2 mm, while the support wire measures 1.8 × 2.5 mm. The slot opening between the profile wires is 0.6 mm.
These dimensions work together. The profile wire affects the slot shape and available filtration area, while the support wire helps the screen resist pressure and maintain a consistent opening.
A wider or heavier wire may increase strength, but it can also reduce open area. A lighter structure may allow more flow but may not provide enough support under higher differential pressure. The best combination depends on the operating conditions.
The Wedge Wire Screen Pipe product range shows how cylindrical continuous-slot screens can be produced with different sizes and structures for industrial filtration systems.
Slot size is often one of the first specifications buyers provide, but it should be based on the material being separated.
The two sample screens use a 0.6 mm continuous slot. This gives the screen a defined opening at the filtering surface, but the real separation result still depends on the shape and behavior of the solids.
A round, rigid particle behaves differently from a long fiber or a soft particle that can change shape under pressure. This is why particle size alone may not be enough for a difficult filtration application.
When possible, buyers should provide information about the solids or send a sample. This is particularly useful for resin, catalyst, slurry, mineral, and process-water applications where particle shape can vary.
The slot should also be considered together with cleaning requirements. Very small openings may improve retention, but they can also increase pressure loss and become blocked more quickly if the process contains sticky or fibrous material.
Once the filtration structure is clear, the screen must be designed to fit the actual equipment.
The two custom reverse screen examples use the same basic construction but different diameters.
Specification | Version A | Version B |
|---|---|---|
Material | SS316Ti | SS316Ti |
Diameter | 82 mm | 52 mm |
Slot size | 0.6 mm | 0.6 mm |
Profile wire | 1 × 2 mm | 1 × 2 mm |
Support wire | 1.8 × 2.5 mm | 1.8 × 2.5 mm |
Length | 85 mm | 85 mm |
End connection | Welded rings | Welded rings |
Ring size | OD 82 mm × H 10 mm | OD 52 mm × H 10 mm |
Both versions use an 85 mm length and the same wire dimensions. The difference in diameter allows the same filtration concept to fit different housings or equipment connections.
The 82 mm version also has a larger circumference, which can provide more filtering surface when other design details remain similar. However, actual capacity should be checked using the final open area and process flow requirement.
Both screens are specified in SS316Ti.
This stainless steel can be suitable for many process-water and corrosive filtration applications, especially where corrosion resistance and welded construction are important. However, material selection should still be based on the actual fluid.
Buyers should consider temperature, pH, chloride content, chemicals, cleaning agents, and abrasive solids. A material that performs well in normal process water may not perform the same way in a hot chloride solution or a strong chemical environment.
The alloy should therefore be confirmed before production rather than treated as a standard choice for every reverse screen application.
The welded end rings may look like a small detail, but they can determine whether the screen installs correctly.
The 82 mm screen uses an end ring with an outside diameter of 82 mm and a height of 10 mm. The 52 mm screen uses a matching 52 mm ring with the same height.
These dimensions should match the surrounding housing, seat, clamp, gasket, or welded connection.
A screen may meet the correct slot and material requirements but still cause installation problems if the ring diameter, length, or roundness does not match the equipment.
For this reason, the final drawing should show the screen body and the parts that connect to the surrounding system.
Custom filtration parts depend heavily on manufacturing consistency.
The slot opening needs to remain even around the screen. The cylinder should stay round, the profile wires should remain aligned, and the support wires should be welded firmly without creating excessive distortion.
Welding is especially important in a compact screen because many joints are close together. Poor heat control can affect the slot width or pull the screen out of shape.
Xinlu’s production process includes wire forming, welding, grinding, polishing, surface treatment, and finished-product inspection. These steps help control the dimensions and surface condition of custom wedge wire components.
The level of inspection should match the project. Standard industrial orders may focus on dimensions, slot size, material, weld condition, and visual quality. More demanding OEM or process projects may also require material certificates, dimensional inspection records, or third-party inspection.
Before production, the drawing should clearly show the diameter, length, wire dimensions, slot tolerance, end-ring dimensions, and flow direction. Important fit dimensions should also have practical tolerances.
Extremely tight tolerances are not always necessary. They can add manufacturing cost without improving performance. The key is to control the dimensions that affect filtration, strength, sealing, and installation.
The quality of a quotation depends on the information supplied with the inquiry.
Instead of sending only a product name and slot size, buyers should provide enough information to understand both the screen and its working conditions.
For the two reference screens, a useful RFQ would identify SS316Ti as the material, 0.6 mm as the slot opening, 1 × 2 mm as the internal axial profile wire, and 1.8 × 2.5 mm as the external circumferential support wire. It would also include the 85 mm length, required diameter, welded-ring dimensions, quantity, and inside-to-outside flow direction.
Process information makes the quotation more useful. Flow rate, pressure, temperature, fluid type, solids characteristics, and cleaning method can help the manufacturer identify possible design concerns before production begins.
If the screen will be installed as an OEM component, a drawing of the surrounding housing can also help. This makes it easier to check connection dimensions and avoid fit problems later.
A related wedge wire filter cartridge may use a similar compact cylindrical form, but the final screen structure should always follow the actual equipment design.
Xinlu also provides custom wedge wire screen services for different materials, dimensions, slot openings, and end connections.
Custom reverse screens are most useful when a standard cylindrical screen cannot fully match the system layout or operating conditions.
They may be used in process-water filters, resin and catalyst retention systems, chemical equipment, compact filtration cartridges, distribution assemblies, and other industrial systems that need inside-to-outside flow.
They can also be used when equipment has limited installation space. The 52 mm and 82 mm examples show how a short 85 mm screen can be adapted to different housing sizes while keeping the same basic filtration structure.
Xinlu supplies wedge wire components for water treatment, chemical processing, mining, food and beverage, petroleum, and other industrial applications. The exact design still needs to reflect the conditions of each project.
A custom design is most valuable when it solves a real requirement, such as a special flow direction, a specific housing diameter, a defined slot opening, or a non-standard end connection. Customization should improve fit and filtration performance rather than simply add complexity.
A custom reverse wedge wire screen should be designed around the filtration process and the equipment in which it will operate.
Buyers should confirm the inside-to-outside flow direction, slot opening, profile-wire and support-wire arrangement, screen dimensions, material, operating pressure, and end connection before production.
The two SS316Ti examples show how the same reverse screen structure can be adapted to 52 mm and 82 mm diameters while keeping a 0.6 mm slot, 85 mm length, and the same wire configuration.
Clear technical information makes the purchasing process easier for both sides. It also reduces the risk of incorrect dimensions, poor equipment fit, or a screen that does not provide the required flow.
