How Nickel Perforated Filter Plates Improve Acid-Resistant System Durability

Nickel-based perforated filter plates have become a cornerstone in industries where strong acid exposure, high temperature operation, and long-term chemical resistance are required. From sulfuric acid scrubbers to hydrochloric acid tanks, these filter plates provide unmatched corrosion resistance while maintaining structural strength and flow optimization.

This article explores how nickel perforated filter plates outperform stainless steel or titanium alternatives in aggressive chemical environments. Through technical breakdowns, application case studies, and standard references, you’ll gain a full understanding of how to implement nickel-based filtration solutions into your system architecture.

Nickel’s Chemical Resistance vs Other Metals

Nickel demonstrates superior performance against a wide range of acidic compounds. While 316L stainless steel offers fair corrosion resistance, it quickly degrades in environments with concentrated sulfuric or hydrochloric acid. Titanium fares better but can suffer embrittlement in redox-heavy operations.

Nickel advantages:

• High resistance to strong acids at elevated temperatures

• Maintains ductility and strength over prolonged exposure

• Resistant to cracking and pitting in acidic chloride media

Key Use Cases in Acidic Systems

• Electroplating plants: Nickel plates serve as flow baffles and anode compartment filters.

• Chemical scrubbers: Filter plates used in SO₂/HCl absorption columns.

• Acid cleaning systems: Tank base filters withstanding cyclic immersion and aeration.

Case Study: Vietnam Chemical Refinery

A Vietnam-based refinery replaced hastelloy mesh with custom nickel filter plates in their H₂SO₄ evaporation circuit. Results:

• Filter lifespan increased from 8 months to 3 years

• Maintenance downtime reduced by 61%

• Panels sustained over 150°C operating temperature

Filter Plate Geometry & Hole Design

Hole configurations directly affect flow uniformity, pressure drop, and debris capture efficiency. We support:

• Hole shapes: round, slot, ellipse, hexagon

• Open area range: 12% to 45%

• Plate thickness: 0.6mm – 3.0mm

• Optional features: flanges, edge folds, reinforcement ribs

Why Choose Nickel over Titanium?

• Nickel is more cost-effective in certain acid-rich environments

• Better thermal expansion compatibility with glass-lined reactors

• Lower galvanic reaction risk when in contact with carbon steel
