⭐ Introduction to Stainless Steel Filter Elements
Stainless steel filter elements are essential components in industrial filtration systems. They provide high strength, corrosion resistance, high-temperature tolerance, and long service life. Compared with disposable filter media, stainless steel elements can be cleaned, reused, and customized for different industries and flow conditions.
Common applications include oil & gas, chemical processing, water treatment, food and beverage production, pharmaceuticals, and air filtration.
⭐ Types of Filter Elements
Industrial filter elements come in multiple structures depending on filtration accuracy and working conditions.
1. Woven Wire Mesh Filter Elements
Made from plain weave, twill weave, or dutch weave stainless steel mesh.
Features：
Precise micron rating
Good mechanical strength
High flow rate
Reusable
Typical forms: filter tubes, filter discs, mesh cylinders.
2. Pleated (Folded) Filter Elements
Pleated stainless steel mesh increases the filtration area by 5–10 times.
Advantages：
Higher dirt-holding capacity
Low pressure drop
Suitable for fine filtration
Widely used in hydraulic systems, polymer filtration, and process liquids.
3. Sintered Filter Elements
Made by sintering multiple layers of wire mesh under high temperature.
Benefits：
Uniform pore size
High strength and rigidity
Withstand high temperature & corrosion
Excellent backwash performance
Commonly used in petrochemical and high-pressure filtration systems.
4. Perforated + Mesh Reinforced Elements
A combination of perforated metal as support and mesh as filtration media.
Used for：
High pressure conditions
Large flow systems
Protection of inner layers
⭐ Materials Used for Filter Elements
The most common materials include:
SS304 / SS304L
General-purpose filtration, corrosion-resistant.SS316 / SS316L
Better corrosion resistance, suitable for food & chemical applications.SS310 / SS904L
For high temperature and strong acid/alkali environments.Monel / Hastelloy / Duplex Steel
Used when corrosion conditions are extremely severe.
