HENGKO sintered stainless steel sparger pipe is designed for stable and uniform gas diffusion in tanks, reactors, hydrogen-water equipment and customized gas–liquid processing systems.
Material: Food-grade 316L stainless steel
Standard pore size: 2 μm nominal
Primary function: Fine and consistent microbubble generation
Customization: Pore size, dimensions, connections and porous length
Engineered for equipment manufacturers, system integrators and process engineers requiring reliable gas distribution and long service life.
The controlled porous structure distributes gas through thousands of micropores, helping reduce large and uneven bubbles.
Provides good corrosion resistance, structural strength and compatibility with many water and gas processing environments.
The integrated porous-metal body does not rely on loose filtering media and provides stable mechanical performance.
Suitable for operating conditions where conventional plastic diffusers may deform, age or lose dimensional stability.
Depending on the process medium, the sparger may be cleaned by back flushing, ultrasonic cleaning or compatible chemical cleaning.
Custom diameters, lengths, porous areas, interfaces, end caps and complete assemblies are available.
The following specifications describe common configurations. Final parameters should be confirmed according to actual operating conditions.
