Customize Porous Alumina Tube for Filtration, Diffusion & Process Control

Porous Alumina Tube Applications

• Cross-Flow Microfiltration Support (Water & Wastewater)

  ✅ Key Advantages

  1. CIP-tolerant support — withstands frequent chemical cleaning and elevated temperatures with stable permeability.
  2. Dimensional consistency — controlled ID/OD enables uniform module potting and seal compression.
  3. Low particle shedding — ceramic matrix resists abrasion in cross-flow conditions.

  ✅ Problem Solved

  An OEM retrofitted polymeric support elements with porous alumina tubes to handle aggressive cleaning cycles. The change allowed higher cleaning frequency without deformation, kept trans-membrane pressure stable over extended runs, and reduced mid-campaign element swaps. System uptime improved, and consumable costs decreased due to longer service intervals.

• Gas Sparging / Diffusion in Bioprocess & Chemical Vessels

  ✅ Key Advantages

  1. Uniform bubble distribution — fine interconnected pores create a consistent bubble size for efficient mass transfer.
  2. Oxidising-media stability — alumina remains stable where sintered metals risk oxidation or ion shedding.
  3. Electrical insulation — safer integration near probes or energized components.

  ✅ ️Problem Solved

  A fermentation line required uniform micro-bubbles and non-metallic contact surfaces. Porous alumina diffusers met the gas flow target at the specified pressure and maintained distribution uniformity after repeated sterilization and chemical exposure, eliminating variability seen with previous metal diffusers.

•  Thermal Process Isolation & Sensor Protection

  ✅ ️Key Advantages

  1. High-temperature integrity — matrix retains structure near furnace zones and cycling profiles used by OEMs.
  2. Selective permeability — allows purge gas flow while shielding sensitive probes from particulates.
  3. Non-conductive body — reduces risk of electrical interference around instrumentation.

  ✅ ️Problem Solved

  An industrial furnace builder used one-end-closed porous alumina tubes to protect thermocouples from particulates while allowing purge gases to pass. Temperature readings stabilized, sensor drift decreased, and replacement intervals lengthened across multiple production lots.

Alumina Porous Ceramic Tube Usage Instructions

• Installation

  1. Support the tube evenly along its full length; avoid point loading.
  2. Use seal compression or potting adhesives designed for ceramics.

• Operation

  1. Ramp temperature gradually and avoid sudden quenching.
  2. For diffusion applications, set gas flow/ΔP within the specified permeability band.

• Storage & Maintenance

  1. Store in a dry environment, inside original protective sleeves.
  2. Place tubes on horizontal supports to prevent bowing or deformation.

• Cleaning

  1. Flush with filtered water to remove loose particulates.
  2. For fouling, use recommended alkaline or oxidizing solutions at controlled temperature, followed by thorough rinsing.

• Disposal

  1. Collect used porous alumina tubes separately; avoid mixing with general waste.
  2. Non-hazardous tubes can be disposed of as inert ceramic material according to local regulations.
  3. If tubes were exposed to chemicals or hazardous media, follow your facility’s hazardous waste protocol and provide material safety documentation.

• Common Mistakes & Fixes

  1. Over-tightening clamps → replace with saddle supports to distribute load.
  2. Thermal shock from cold liquid on hot tubes → allow cooling before cleaning.
  3. Chemical incompatibility → confirm solution pH and oxidizer concentration with the supplier.
