Sintered Porous Metal Tubes in 316L SS & Titanium
Sintered porous tubes in 316L stainless steel or pure titanium. Open-ended tube format for installation in custom housings, reactors, or sparger assemblies.
Sintered Porous Metal Tubes in 316L SS & Titanium
Wall thickness 2–10 mm; outer diameter φ14–200 mm; length 100–1200 mm as a single-piece tube without joins. End configurations include plain cut (for weld-in or compression-fit installation), flanged, or threaded ends for direct pipe connection. Welded end caps for use as complete cartridge elements are also available, and double-open (open at both ends) configurations allow bidirectional flow for backpulse or reverse-flush cleaning.
Confirm material compatibility for the actual medium, concentration, temperature and operating conditions before ordering. Titanium is not specified here as universally resistant to hydrochloric or sulfuric acid.
How to Select a Sintered Porous Metal Tube
Define the duty first: filtration, gas sparging, aeration, flow distribution, or a reactor internal. For filtration, specify the particle size to be controlled, flow rate, pressure, allowable pressure drop, and cleaning cycle. For sparging or gas distribution, specify the gas, liquid, immersion depth, and the bubble or flow-distribution objective. These inputs determine pore range, wall thickness, active area, and end configuration.
Use 316L for general industrial service and evaluate pure titanium when chloride, oxidising, or acidic process conditions govern material selection. For flat gas-distribution or filter-media formats, see sintered porous plates; for compact point-of-use components, see sintered porous discs. FILTURE can review the complete duty through a technical RFQ.

Engineering Highlights of SS/Ti Porous Tubes
Open-Ended Tube Format
Supplied without end caps — plain cut, flanged, or threaded ends for direct integration into customer-designed housings and assemblies.
Custom Dimensions to Drawing
Non-standard OD, wall thickness, length, and end-cap geometry all available. Tolerances to ±0.1 mm on critical dimensions.
SS or Ti — Same Pore Range
0.22–100 µm · Confirm material compatibility for the actual medium, concentration, temperature and operating conditions before ordering. Titanium is not specified here as universally resistant to hydrochloric or sulfuric acid.
Backwashable
Select cleaning chemistry, temperature and reverse-flow pressure for the material and deposited contaminants. Reuse depends on inspection and agreed performance checks after cleaning; unchanged structure or unlimited regeneration is not guaranteed.
Double-Open Configuration Available
Open at both ends for bidirectional flow — maximises filtration area utilisation and enables reverse-flow or back-pulse cleaning from either direction.
Material & Dimensional Records
Chemical composition data for raw material and dimensional inspection records for finished products available on request.
Typical Applications for SS/Ti Porous Tubes
Ozone Sparger Tubes
Distribute fine ozone bubbles into water treatment reactors. Ti tubes used where ozone-resistant material is required; spherical/dome-shaped aeration heads with a 1/2" NPT connection are also available for fine-bubble aeration in recirculating aquaculture systems.
φ20–180 mm · 5–50 µm · Ti or SSReactor Filter Elements
Weld-in porous tube assemblies for in-situ filtration inside chemical reactors — removes catalyst particles or product crystals from reaction mixture.
2–50 µm · High-alloy optionsIn-Line Pipeline Filtration
Threaded or flanged tube elements for direct pipe installation in liquid and gas process lines.
5–100 µm · SS or TiGas Diffusion and Distribution
Porous tubes for uniform gas injection into liquid columns in absorption, stripping, and aeration systems.
5–50 µm · Low ΔP · Custom ODPEM Electrolyzer Components
Ti porous tubes for flow field and distribution elements in PEM electrolyzer modules.
1–10 µm · Pure Ti · CustomChlor-Alkali Brine and Chlorine Gas Filtration
Ti tubes up to φ200 mm for secondary brine polishing and wet chlorine gas demisting ahead of membrane cells and compressors — titanium's passive oxide layer resists the chlorine and hypochlorite environment.
φ up to 200 mm · Ti · 30 µmPharmaceutical Sparging
Sterile gas sparging into bioreactors and fermenters. Ti or 316L SS for cleanable pharmaceutical service.
5–20 µmIndustrial Circulating Water Filtration
Ti tubes down to 0.22 µm for suspended solids removal in circulating water systems, including ozone-disinfected loops. Backwash at 3–5 bar restores flow without media replacement.
