Sintered Stainless Steel Wire Mesh Filter for High-Temp / High-Pressure

Product overview

Sintered Stainless Steel Wire Mesh Filters are engineered filtration elements where woven stainless cloth is bonded by sintering to create a mechanically integrated, gradient-porosity medium. Unlike loose woven or pleated cloth alone, sintered constructs deliver dimensional stability, minimal media migration, and predictable retention under severe thermal and pressure cycling — making them ideal for petrochemical reactors, steam systems, HTF loops, and high-pressure gas/liquid separation.

Why sintered wire mesh?
Sintering fuses mesh layers at contact points to produce a monolithic porous body: this eliminates yarn movement, increases burst resistance and enables stable cut-sizes across a wide range of operating conditions. The graded porosity technique (coarse support layers bonded to fine surface layers) yields high dirt-holding capacity with low initial ΔP — a practical alternative to sintered powder metal when you need open-structure permeability and easier cleanability.

Product Specification Sheet

Configurations & materials
Typical builds include 2–6 layer stacks (support → transition → polishing layer) sintered together and axially pleated or formed into cartridges. Materials are selected for chemistry and temperature: SS316L for general corrosive liquid service, SS321 for oxidation resistance at elevated temperatures, and nickel alloys (Inconel) for extremely aggressive media. End fittings and housings are available in welded stainless or flanged carbon/duplex options to suit plant interfaces.

Performance & cleaning
Sintered mesh tolerates steam-sterilization, thermal shocks and high ΔP backflush cycles. Cleaning options include high-temperature steam, alkaline/acid CIP, ultrasonic baths and controlled thermal oxidation for organic foulants. Performance documentation includes porosity (%) vs. permeability curves, retention (βx) testing, and recommended regeneration recipes — essential for B2B procurement and qualification.

Applications
Common uses: high-temperature catalyst protection screens, hot oil and molten metal filtration guards, high-pressure steam straining, turbine lube oil polishing at elevated temps, flue gas particulate pre-filtration, and high-temp membrane pre-treatment. For gas service they act as coalescing pre-filters when combined with hydrophobic treatments.
