SS/MS Filter Housing

Introduction :

Industrial metallic filter housings are crucial components in filtration systems used across various industries, including manufacturing, pharmaceuticals, food and beverage, and petrochemicals. These housings are designed to hold and support filter elements while ensuring efficient and reliable filtration of fluids, including liquids and gases. Their robust construction is essential for withstanding harsh operating conditions and ensuring long-term performance.

Technical Specifications

1. Material of Construction :

   • Stainless Steel (SS) : Commonly used due to its corrosion resistance and durability. Grades include SS304, SS316, and SS316L.
   • Carbon Steel : Used in less corrosive environments, often coated or lined to prevent rust.
   • Alloy Steel : For high-temperature and high-pressure applications.

2. Design and Construction :

   • Body Types : Can be cylindrical, rectangular, or custom shapes depending on the application.
   • End Connections : Flanged, threaded, or welded connections to match system requirements.
   • Mounting Options : Typically include brackets or legs for secure installation.

3. Size and Capacity :

   • Diameter : Ranges from small (e.g., 2 inches) to large (e.g., 48 inches or more) depending on the flow requirements.
   • Length/Height : Variable, often designed based on the required filter element length.
   • Flow Rate : Specified in gallons per minute (GPM) or liters per minute (LPM) based on application needs.

4. Filter Element Compatibility :

   • Type : Can accommodate various types of filter elements such as pleated, bag, cartridge, or mesh filters.
   • Size : Designed to fit standard or custom-sized filter elements.

5. Pressure Rating :

   • Working Pressure : Typically ranges from 150 PSI to 1500 PSI or higher depending on the material and design.
   • Testing : Must meet pressure vessel standards and undergo hydrostatic or pneumatic testing.

6. Temperature Rating :

   • Operating Temperature : Can range from cryogenic temperatures to high temperatures (e.g., 600°F/315°C) depending on material and design.

7. Seals and Gaskets :

   • Materials : Often made from Viton, EPDM, PTFE, or other materials suitable for the operating environment.
   • Design : Must ensure a leak-proof seal between the filter housing and the filter element.

8. Surface Finish :

   • Internal Surface : Typically polished or passivated to reduce particle shedding and enhance cleanliness.
   • External Surface : May be painted, coated, or polished for corrosion resistance and aesthetics.

9. Special Features :

   • Drain and Vent Ports : For cleaning and maintenance purposes.
   • Pressure and Differential Pressure Indicators : For monitoring performance and filter status.
   • Automatic or Manual Venting : To release trapped air or gas.

Applications : 

• Liquid Filtration : Removing particulates from process fluids, chemicals, or water in various industries.
• Gas Filtration : Ensuring clean air or gas streams in industrial processes or HVAC systems.
• Hydraulic Systems : Protecting hydraulic circuits from contaminants to ensure reliable operation.
• Food and Beverage : Ensuring compliance with sanitary standards for product safety.
