Technical articles, material guides, and application notes from our engineering team. Written for process engineers, project managers, and procurement specialists who specify or purchase wedge wire screens.
How to Select the Right Slot Aperture for Your Application
Slot aperture is the single most critical specification in a wedge wire screen. Too narrow and throughput drops. Too wide and target particles pass through. This guide covers how to determine the right slot size based on your particle distribution, flow requirements, and operating conditions.
Sieve Bend vs Flat Panel: When to Use Which
Both sieve bends and flat panels are used for dewatering and sizing, but they serve different applications. This comparison helps you decide which screen type fits your process.
Wire Tilt Angle in Wedge Wire Screens: Engineering Guide
Wire tilt angle adds a shearing flow mechanism to standard orifice flow, increasing effective capacity by 15-30%. This guide covers tilt angle selection, performance impact, and application-specific recommendations.
Wedge Wire vs Woven Mesh and Perforated Plate
Side-by-side comparison of wedge wire against woven wire mesh and perforated plate. Covers structure, open area, clog resistance, service life, and cost.
How to Specify a Wedge Wire Screen: Step by Step
Six-step process for specifying a wedge wire screen, from defining the process objective to selecting material grade and end connections.
Material Selection Guide for Wedge Wire Screens
Complete material selection guide covering stainless steel (304, 316L, Duplex, Super Duplex), high-temperature alloys, and carbon steels for wedge wire screens.
Selecting Wedge Wire Screens for Seawater and Desalination
Seawater is one of the most demanding environments for screening equipment. Chloride corrosion, marine growth, and regulatory compliance all affect screen specification.
Pickling and Passivation for Stainless Steel Wedge Wire Screens
Pickling removes heat tint and oxide scale from welding. Passivation rebuilds the chromium oxide layer that gives stainless steel its corrosion resistance. Both are essential for screens in corrosive or hygienic environments.
Mechanical Polishing vs Electropolishing for Wedge Wire Screens
Mechanical polishing uses physical abrasives to achieve Ra 0.5-0.8 micrometers. Electropolishing is an electrochemical process that dissolves surface peaks, achieving Ra 0.2-0.4 micrometers with superior cleanability for food and pharmaceutical applications.
Wedge Wire Screen Service Life by Material and Application
Expected service life for wedge wire screens across stainless steel, duplex, and carbon steel grades in different operating environments.
Material and Surface Finish for Food-Grade Wedge Wire Screens
Requirements for food-grade wedge wire screens including material grades, surface finishes, regulatory standards, and hygienic design principles.
Understanding Open Area in Wedge Wire Screens
Open area is the percentage of a screen surface available for flow. It determines throughput capacity, pressure drop, and screen sizing. Here is how to calculate it and why it matters.
Coanda Effect in Intake Screens: How It Works
Coanda intake screens use a hydrodynamic principle to provide self-cleaning water intake with no moving parts and no power. This article explains the operating principle and where it applies.
How V-Wire Profile Geometry Affects Screen Performance
The V-shaped wire cross-section delivers four specific performance advantages over round wire and flat wire profiles.
Total Cost of Ownership: Wedge Wire vs Alternative Screens
Wedge wire screens cost more upfront but deliver lower total cost over the equipment lifetime. Breakdown of replacement, downtime, and maintenance factors.
Emerging Trends in Wedge Wire Screen Technology
Key trends include advanced alloys for lithium extraction and geothermal, CNC-integrated welding with laser QC, expanding use in desalination and carbon capture, and full recyclability as a sustainability advantage.
What Causes Screen Blinding and How to Prevent It
Screen blinding (clogging) reduces throughput and increases maintenance cycles. This article explains the mechanisms behind blinding and how wedge wire's V-profile geometry helps prevent it.
Wedge Wire Screen Maintenance Guide
A properly maintained wedge wire screen can last 8 to 15 years in most applications. This guide covers inspection intervals, cleaning methods, and when to replace rather than repair.
