Our Gas Diffusion Layer (GDL) tubes are specially engineered for demanding petrochemical applications, where controlled gas flow, chemical resistance, and structural integrity are essential. Designed using advanced porous metal technology, these tubes ensure uniform gas distribution, high thermal tolerance, and long operational life, even in harsh chemical processing environments.
✅ Uniform Gas Flow Distribution
Our porous structure ensures even gas dispersion across the tube surface, critical in processes such as reactor gas injection, dehydration systems, and gas-solid reactions.
✅ High Corrosion Resistance
Manufactured using 316L stainless steel, Hastelloy, or titanium, our GDL tubes can handle acidic, alkaline, and high-sulfur environments typical in petrochemical plants.
✅ Thermal Stability & Pressure Resistance
Withstand temperatures up to 600°C and pressures up to 20 MPa, making them suitable for extreme gas delivery systems.
✅ Customizable Micron Ratings
Available in pore sizes from 1–50 microns, with typical configurations at 5 or 10 microns for optimal gas permeability and precision control.
✅ Long Service Life & Low Maintenance
The rigid porous metal design allows for backflushing, ultrasonic cleaning, and long-term reuse.
