Sintered Porous Metal Filter Tube & Cartridge in 316L Stainless Steel (AISI 316L (1.4404)) is used for filtering gases, steam, solvents and process liquids through rigid sintered stainless powder tubes that can be back-flushed and reused for years. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L Stainless Steel Sintered Porous Metal Filter Tube & Cartridge Is Used
- Chemical & petrochemical: catalyst recovery and solvent polishing filters.
- Gas & steam: process gas, nitrogen and clean steam filtration.
- Pharmaceutical & food: sterile vent and steam filters with welded fittings.
- Semiconductor & instrumentation: gas line and sampling filters.
Ordering Sintered Porous Metal Filter Tube & Cartridge in 316L Stainless Steel
- Micron rating: From 0.5 to 100 µm; specify liquid or gas rating, which differ for the same element.
- Dimensions & wall: OD, length and wall thickness set flow and strength.
- End fittings: Welded caps, NPT, DOE, 222/226 O-ring or flanged ends.
Mistakes to Avoid with Sintered Porous Metal Filter Tube & Cartridge
- Specifying a micron rating without the permeability or flow rate.
- Over-tightening threaded ends, which cracks the porous body.
