Custom PTFE Grids & Perforated Support Plates | Chemical Column Internals
Product Overview & Engineering Excellence
Custom-Machined PTFE Packing Grids & Perforated Support Plates for Corrosive Tower InternalsEngineered from premium compression-molded virgin PTFE, these tower internals deliver total chemical inertness, high mechanical strength, and outstanding thermal stability. Available in solid perforated plate designs, bar-grid constructions, multi-piece segmented trays, and gas-injection support assemblies, our PTFE grids are custom-machined to match exact column inner diameters, flange bolting patterns, and process flow requirements.
Key Performance Advantages
-
Universal Chemical Immunity: Fully inert across the entire pH range (0 to 14), resisting concentrated acids, strong caustics, halogens, and organic solvents.
-
Optimized Open Area Ratio: Precision-drilled hole patterns and slot geometries minimize pressure drop across packed beds while preventing packing migration.
-
High Load-Bearing Capacity: Rigid, thick-section construction supports heavy random or structured packing beds without sagging or creep deformation.
-
Non-Stick & Anti-Fouling: Low surface energy prevents polymer buildup, scaling, and solid particulate accumulation, ensuring consistent mass transfer efficiency.
-
Wide Operating Temperature Range: Operates continuously from deep cryogenic temperatures up to 260 degrees Celsius.
Product Types & Design Options
-
Perforated Sieve Plates: Flat PTFE discs with uniform drilled hole arrays and perimeter mounting bolt holes for direct flange clamping.
-
Structured Bar Grids: Heavy-duty slotted assemblies fabricated from thick PTFE bars for maximum open flow area and heavy bed support.
-
Riser & Gas-Injection Trays: Advanced internals equipped with gas riser tubes and liquid downcomers for optimized phase distribution.
-
Segmented Multi-Piece Designs: Large-diameter support grids split into interlocking sections to pass through vessel manways for easy onsite assembly.
Primary Applications
-
Chemical Absorption & Scrubbing Towers: Acid gas absorbers, chlorine drying towers, and hazardous air pollutant scrubbers.
-
Distillation & Stripping Columns: Mass transfer towers handling aggressive solvents, organic acids, or reactive chemicals.
-
Fine Chemical & Pharmaceutical Vessels: Clean, non-contaminating packing supports for batch reaction and purification columns.
-
Wastewater Treatment & Neutralization: Gas stripping and chemical recovery vessels operating in corrosive environments.
Quality Assurance, Inspection & Packaging
-
Precision Machining Checks: 100% verification of plate diameter, thickness, hole pitch, counterbores, and bolt circle dimensions using digital calipers.
-
Surface Integrity Quality Control: Inspected to ensure all drilled perforations and slots are smooth, deburred, and free of machining chips or cracks.
-
Protective Export Packaging: Cleaned, wrapped in protective plastic film, cushioned with foam inserts, and packed in reinforced wooden cases to preserve flatness and hole geometry during shipping.
