Stainless Steel Mesh Filter Discs—Precision engineered for multi-industry filtration requirements

Market Trends & Industry Overview

The global filtration market for stainless steel mesh filter discs is expected to reach $5.8 billion by 2028 (CAGR: 6.4%, 2022-2028, Source: Grand View Research), driven by increasing regulatory requirements (ISO 16889, ANSI B31.1) for chemical purity, energy efficiency, and sustainability.
Key Segments: Sintered mesh discs, multilayer composite discs, pleated filter discs, and precision laser-cut wire cloth discs.
Emerging Directions: Adoption of higher alloy grades (316L, Hastelloy, Inconel, Nichrome), finer micron rating (2–20 μm), and hybrid discs for backwashable systems.

Expert FAQ: Stainless Steel Mesh Filter Discs

Q1: What is the difference between woven mesh and sintered metal filter discs?

Woven mesh discs use interlaced stainless steel wires without fusion, yielding flexibility and moderate strength, suitable for general filtration. Sintered metal discs employ multiple mesh layers fused by high temperature, resulting in a rigid, uniform pore, high‐pressure tolerant filter—especially for critical, high-contaminant applications.

Q2: Which grades of stainless steel & alloy are recommended for corrosive environments?

SS 316L is standard, with Hastelloy/C-276 or Nichrome (Ni80Cr20) suitable for high-chloride acid/alkali and >800℃ continuous use. See all options in the Nichrome Filter Element Disc datasheet.

Q3: How is filter fineness specified and verified?

Fineness (microns/μm) describes minimum retained particle size; tested by bubble point method per ISO 29463. Required tolerance ±8%

Q4: What are the main installation standards?

Discs are installed per vessel flange or capsule housing dimensions. Conformance to ANSI B16.5/B31.1 ensures sealability; FDA/cleanroom discs require hydroalcohol cleaning and vacuum-packing.

Q5: Can you provide custom design for special geometry or pleated types?

Absolutely. We support custom geometry, edge bonds (weld/rim), pleated and multilayer stack configurations—with CAD/drawing approval.

Q6: How are discs tested for durability?

Each batch undergoes high-velocity backflush, acid/base soak, and >1.3 million cycle pressure tests—life exceeded 22,400 hours in chemical pilot line (2022 case).

Q7: What is the typical lead time and how is quality ensured?

Standard lead time: 5–12 days (ocean/air freight according to size). QA per ISO 16889/9001: 100% inspection; factory supports third-party audit by client.
