Complete PTFE Fluoropolymer Lining Stainless
Steel Filter Housing for Extreme Corrosive Applications
This Stainless Steel Filter Housing with PTFE Lining features a dual-protection design with
a robust steel shell fully lined with PTFE, offering both structural strength and complete
corrosion resistance. It safely handles highly aggressive media such as concentrated
sulfuric acid and caustic soda. Each unit undergoes spark and hydrostatic pressure
testing to ensure lining integrity, providing reliable filtration in demanding chemical processes.
Precision filtration of strong acids including sulfuric, hydrochloric and nitric acid
Safe filtration of caustic soda, liquid chlorine and other strong alkaline media
Process filtration of corrosive intermediates in esterification, sulfonation reactions
Continuous filtration of high concentration plating solutions and chemical baths
Purification filtration of corrosive pharmaceutical intermediates
Processing of chlorine/fluorine containing raw materials and product refinement
Complete Corrosion Protection
Full PTFE lining creates an effective barrier against most strong acids, alkalis and organic solvents
Reliable Quality Verification
Spark testing ensures defect-free lining combined with hydrostatic tests for structural integrity
Optimized Fluid Performance
Low friction coefficient of PTFE surface ensures smooth material flow, easy cleaning
Robust Dual-Layer Structure
Metal shell provides mechanical strength while plastic lining ensures chemical stability
Maintains performance from -100°C to +150°C, adapting to temperature fluctuations

How do I choose the right stainless steel pleated filter cartridge for my application?
Selection should be based on your process fluid, required filtration rating, operating temperature, flow rate, pressure conditions, cartridge dimensions, end-cap type, and seal material. For high-temperature, viscous, chemical, compressed-air, or liquid-cooling applications, these parameters should be evaluated together rather than selecting only by micron rating.
What micron rating should I choose for a stainless steel pleated filter cartridge?
The appropriate micron rating depends on the particle size to be removed, required downstream cleanliness, contamination load, flow requirement, and the role of the filter in the system. This stainless steel pleated filter cartridge is commonly available in the 5–200 μm range, with other ratings selectable according to specific process requirements.
Is this stainless steel filter cartridge suitable for high-temperature and high-viscosity fluids?
Yes, its all-metal sintered stainless steel construction is designed for demanding filtration conditions where polymer filter media may be unsuitable. It can be considered for high-temperature oils, resins, polymer melts, chemical intermediates, and other viscous fluids, provided the actual temperature, viscosity, pressure, and chemical compatibility are confirmed before selection.
How do I confirm chemical compatibility with my process fluid?
Chemical compatibility should be evaluated based on the stainless steel grade, seal material, fluid composition, concentration, operating temperature, contact time, and cleaning conditions. Available material and seal combinations may vary, so compatibility should be confirmed against your actual process conditions, especially when filtering corrosive chemicals, solvents, acids, or other aggressive fluids.
Can the stainless steel pleated filter cartridge be cleaned and reused?
The sintered stainless steel structure is designed to support cleaning and reuse under suitable conditions. Depending on the contamination type and process requirements, cleaning methods may include chemical cleaning or ultrasonic cleaning. Actual regeneration performance and service life depend on contaminant characteristics, cleaning procedure, differential pressure, and operating conditions.
Can this stainless steel filter cartridge replace my existing cartridge or fit my current housing?
Compatibility depends on the cartridge diameter, length, end-cap configuration, sealing method, and housing interface. Available configurations include multiple lengths, diameters, end caps, and seal materials. To confirm interchangeability, provide your current cartridge model, dimensions, end-cap type, filtration rating, process fluid, and operating conditions before replacement.
