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.


APPLICATIONS

• Basic Chemical Production: Precision filtration of strong acids including sulfuric, hydrochloric and nitric acid

• Chlor-Alkali Industry: Safe filtration of caustic soda, liquid chlorine and other strong alkaline media

• Organic Synthesis: Process filtration of corrosive intermediates in esterification, sulfonation reactions

• Electroplating Industry: Continuous filtration of high concentration plating solutions and chemical baths

• Pharmaceutical API: Purification filtration of corrosive pharmaceutical intermediates

• Pesticide & Dye Manufacturing: Processing of chlorine/fluorine containing raw materials and product refinement



BENEFITS OF SS FILTER HOUSING WITH PTFE LINING 

• 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

• Excellent Thermal Stability

Maintains performance from -100°C to +150°C, adapting to temperature fluctuations
