Inconel Nickel Alloy Wedge Wire Screen Panels & Baskets

Product Overview

Inconel nickel alloy wedge wire screens are heavy-duty, finished screening surfaces designed for terminal solid-liquid separation, sizing, and dewatering in severe environments. Distinct from raw profile wire or tubular filter elements, these products are fabricated into specific structural forms—flat panels, curved sieve bends, and high-strength baskets—engineered to endure high abrasion, extreme corrosive media, and elevated temperatures.

Screen Forms & Specific Capabilities

Because flat panels, curved screens, and rotary baskets require completely different manufacturing and structural considerations, our fabrication capabilities are tailored to each specific form:

1. Flat Screen Panels
   • Applications: Vibrating screen decks, static grids, and false bottoms in chemical tanks.
   • Size Limits: Custom dimensions up to roughly 3000 mm x 6000 mm (subject to factory confirmation based on wire/rod combination and transportation limits).
   • Framing: Typically reinforced with heavy-duty Inconel angle iron, flat bars, or machined borders for bolt-on installation.
2. Curved Screens (Sieve Bends)
   • Applications: Gravity-fed static screens for highly efficient wastewater treatment and starch/mineral dewatering.
   • Geometry: Manufactured to specific arc angles (e.g., 45°, 60°, 90°, 120°) and precise radii to utilize the Coandă effect for fluid separation.
   • Flow Configuration: Cross-flow design where the fluid flows perpendicular to the wedge wires.
3. Centrifuge Baskets (Rotary Applications)
   • Applications: Dynamic separation in industrial decanters and high-speed centrifuges.
   • Engineering Requirements: Unlike static panels, baskets are subjected to high rotational stresses. Concentricity, structural integrity, and dynamic balancing are critical. We fabricate these strictly according to OEM drawings, and dynamic balancing can be conducted based on your specified operating RPM and tolerance requirements.

Specifications Matrix

Please note that these parameters represent our general manufacturing range. Not all extremes can be combined in a single product (e.g., ultra-fine slots are typically not available on the heaviest wire profiles).

Parameter	Standard Capability Range
Slot Opening	0.05 mm to 20.0 mm (Depending on profile wire selection)
Support Rod Spacing	Custom spacing (e.g., 10 mm to 50+ mm) to match mechanical load requirements
Edge & Mounting	Welded, Polyurethane-poured, Rubber-edged, Flanged, or Customized
Overall Thickness	Dependent on the combined height of the selected V-wire and support rod

Open Area Calculation & Clarification

For sizing screens, maximizing flow rate while maintaining structural strength is a balancing act. The Theoretical Surface Open Area is calculated using this formula:
Surface Open Area = [Slot Opening / (Slot Opening + Effective Wire Surface Width)] x 100%.

Important Note: This formula only calculates the open area of the wire surface itself. The Effective Overall Open Area of the finished product will be lower, generally falling between 5% to 45%, because structural reinforcements, support rods, and edge framing create blind spots that reduce total throughput.

Reference Table for Theoretical Surface Open Area (Assuming structural pairing):

Slot Opening (mm)	Recommended Wire Width (mm)	Approx. Surface Open Area (%)	Typical Separation Scenario
0.10 mm	1.0 mm	9.1 %	Fine chemical separation
0.25 mm	1.5 mm	14.3 %	Food / Starch processing
1.00 mm	2.0 mm	33.3 %	Wastewater dewatering
2.00 mm	3.0 mm	40.0 %	Heavy mineral sizing
(Engineers: As slot sizes increase, thicker wire profiles are required to maintain structural rigidity, which naturally limits the maximum open area.)

Appropriate Inconel Grade Selection

We highly recommend matching the alloy specifically to your operating temperature, corrosive media, and mechanical load. (Note: Standard austenitic stainless steels like 304/316L are available via our standard materials division, but this page focuses strictly on high-performance superalloys).

• Inconel 600: Frequently specified for solid-liquid separation panels in corrosive chemical crystallization and certain high-temperature screening processes.
• Inconel 601: Best suited for high-temperature separation screens inside thermal processing units and industrial furnaces due to exceptional oxidation resistance.
• Inconel 625: The material of choice for scrubber sieve plates, offshore desanding screens, and aggressive environmental waste dewatering panels, offering excellent pitting resistance.
• Inconel 718: Evaluated for high-stress dynamic applications (such as specific centrifuge baskets) where its extremely high yield strength and fatigue resistance are required. (Other superalloys like Hastelloy C-276 can be supplied for extreme acidic environments upon request).

OEM Replacement & Custom Fabrication

We possess the fabrication capabilities to manufacture direct drop-in replacements for existing screen panels and OEM centrifuge baskets. By providing us with original manufacturer drawings, structural specifications, or a physical sample, our team will fabricate an exact dimensional match.
Many clients utilize this service to upgrade their existing carbon steel or standard stainless screens to premium Inconel alloys to better handle severe process environments.
