40um Sintered SS316L Multilayer Wire Mesh For High-Pressure Gas & Dust Removal

TOPTITECH's 40um Sintered SS316L Multilayer Wire Mesh for High-Pressure Gas & Dust Removal is manufactured via high-temperature vacuum sintering, fusing multiple layers of woven stainless steel wire mesh into a rigid monolithic porous plate. The five-layer laminated architecture integrates a protective layer, a micron-rated filtration control layer, dispersion layers, and dual support reinforcement layers, achieving uniform pore distribution and tight-tolerance integrity from 1 to 500 microns. SS316L construction delivers continuous operation up to 480℃ with excellent resistance to oxidizing agents, acids, and alkalis. The sintering process permanently bonds all wire intersection points through solid-state diffusion, preventing media migration and wire displacement under differential pressure, thereby maintaining absolute filtration stability across pulse backwashing and reverse flow cleaning cycles.

TOPTITECH's 40um Sintered SS316L Multilayer Wire Mesh for High-Pressure Gas & Dust Removal excels in hot gas filtration and gas-solid separation where high-temperature, corrosive atmospheres and spark-laden streams are present. Typical installations include chemical process off-gas systems, petrochemical reactor gas polishing, power generation flue gas cleaning, fluidized bed distributors, and powder conveying filtration. Porosity typically ranges from 30% to 60%, providing uniform gas distribution with low resistance while maintaining efficient particle retention. The rigid sintered structure withstands mechanical shocks and high-pressure differentials, enabling effective powder collection over thousands of cleaning cycles without deformation. Backflush air cleaning, ultrasonic baths, or thermal regeneration restore full filtration capacity without compromising media integrity, delivering long service life in demanding dust collection and high-pressure gas treatment applications.

Precise Filtration Accuracy

The 40 μm-rated pore size combined with vacuum diffusion bonding across five layers creates a calibrated barrier that captures 40μm and larger particulates with high efficiency, applicable to fluidized bed gas distribution, pulverized coal conveying, and high-temperature flue gas purification where particle breakthrough is unacceptable. The sintering process permanently locks all wire intersection points through metallurgical bonding, eliminating wire migration during pulsating flow or differential pressure spikes.

Rigid Pore Geometry Under High Pressure

The five-layer architecture (protective + filter + dispersion + dual support layers) distributes mechanical stress evenly across the structure. This prevents aperture collapse or deformation under high-pressure differentials-a failure mode common in non-sintered stacked meshes or pleated paper media. The multilayer support design ensures filter rating remains unchanged across thousands of duty cycles.

Oxidation and Chloride Corrosion Margin

SS316L contains 2-3% molybdenum, which enhances pitting resistance in chloride-laden gas streams from chemical process off-gas and incineration flue gas. The continuous dense chromium oxide film that forms on the wire surface resists acidic condensates (SO₂, HCl, H₂S) present in coal-fired boiler and sintering machine exhaust.

Pulse-Jet Cleaning Durability

The rigid monolithic structure withstands high-frequency mechanical stress from reverse pulse cleaning and backflush air cycles without structural yielding. Each cleaning event restores near-original pressure drop by dislodging accumulated dust cake from the smooth wire surface, extending service life beyond disposable media.

Unrestricted Gas Permeability

The combination of square weave stainless steel wire mesh layers with controlled porosity (typically 30-60%) delivers uniform gas distribution across the entire filter face while maintaining efficient particle retention at a 40um rating. This balance between dust capture efficiency and flow capacity prevents energy-wasting backpressure buildup common in dense depth filter media.

Zero Shedding and No Secondary Contamination

The all-metal construction contains no fiberglass, polyester, or resin binders. No media fibers or particulate shedding occurs during filtration or cleaning cycles, essential for powder conveying recovery of high-purity metal powders and pharmaceutical air handling where product contamination cannot be tolerated.

Heavy Industrial Dust Collection & Hot Gas Filtration - The 40um sintered SS316L multilayer wire mesh serves as the core filter medium in blast furnace off-gas purification, converter fume abatement, and iron ore sintering flue gas treatment within steel mills. Operating at continuous temperatures up to 480°C without structural degradation, the rigid five-layer laminate captures PM10, PM2.5, and coarse particulate matter from high-velocity gas streams while withstanding abrasive dust loads and thermal cycling pulse-jet cleaning. This application directly supports compliance with dust emission standards for baghouse retrofits and metal filter cartridges in metallurgical facilities.

Coal-Fired Power Generation & Flue Gas Desulfurization - In thermal power plant boiler exhaust, the sintered mesh filter panel removes fly ash and fine particulates before wet FGD or during dry sorbent injection. The 316L construction resists acidic condensates-sulfur dioxide, hydrogen chloride, and nitrogen oxides-prevalent in flue gas desulfurization scrubber pre-filtration and combustion gas polishing. Pressure drop stability across a 35–60% open area ensures uninterrupted turbine operation while capturing 40μm and larger particles at high differential pressures.

Petrochemical Refining & Catalytic Cracker Off-Gas - In FCCU flue gas cleaning and Rectisol process solid-gas separation, the sintered filter cloth removes entrained catalyst fines and particulates from high-temperature refinery off-gas streams before energy recovery turbines or vent stacks. 316L molybdenum content provides pitting resistance to chloride and sulfur compounds present in hydrotreater tail gas and amine regeneration off-gas. Rigid monolithic design also enables reverse-pulse backwashing for catalyst fines recovery and long asset life.

Waste-to-Energy & Incineration Flue Gas Treatment - The 40um sintered SS316L panel serves as the filtration stage in municipal solid waste incinerator baghouses, medical waste thermal treatment scrubbers, and hazardous waste combustion gas purification systems. High-temperature gases (250–450°C) laden with corrosive dioxin precursors, acid gases, and heavy metal vapors pass through the sintered mesh where particulates are captured without fiber shedding or meltdown at elevated temperatures. The all-metal construction also handles spark-laden streams where polymer-based filtration media would ignite or degrade.

Gas Turbine & Compressor Air Intake Silencing-Filtration - In power plant gas turbine compressor suction systems, the sintered mesh functions as an acoustic attenuator and pre-filter combination, trapping airborne dust, sand, and salt aerosols while maintaining low restriction to air intake flow. The multilayer structure provides mechanical integrity under high-frequency pulsation from compressor blades without wire migration or pore enlargement over thousands of operating hours.

Powder Conveying & Silo Aeration - As a fluidization cloth in bulk solids handling of cement, lime, flour, carbon black, and metal powders, the sintered SS316L sheet distributes compressed air uniformly across the silo cone or hopper outlet, promoting mass flow and eliminating bridging, rat-holing, and discharge interruptions. The rigid sintered structure withstands abrasive powder erosion and supports high-pressure reverse aeration for filter cleaning without rupture-surpassing the service life of woven textile aeration fabrics by years.
