Conical Filter Stainless Steel Mesh

Conical Filter Stainless Steel Mesh: Engineering and Applications

Introduction
Conical filter stainless steel mesh represents a specialized filtration solution designed for high-flow applications in demanding industrial environments. These filters utilize precision-woven stainless steel mesh formed into conical shapes, providing increased surface area for efficient particle retention. The construction typically employs 304 or 316 stainless steel, chosen for its corrosion resistance and mechanical durability in temperatures ranging from -270°C to +550°C.

Manufacturing Process
The production of conical filters involves multiple stages:

• Material Selection: Cold-rolled stainless steel wire (0.02mm-2.5mm diameter) with controlled carbon content (0.08% max for 304)

• Weaving Technique: Plain Dutch weave or twill Dutch weave patterns, achieving filtration ratings from 5-400 microns

• Forming Process: CNC hydroforming creates consistent conical shapes with 15-85° inclusion angles

• Welding: Argon gas protection welding ensures seam integrity under pressure cycles

• Surface Treatment: Electropolishing (Ra ≤ 0.8µm) or passivation per ASTM A967
