Porous Metal Tubes
CMI Porous Metal Tubes are versatile filtration and diffusion elements designed to meet a wide range of industrial specifications. Manufactured through advanced sintering processes, these tubes offer precise pore size distributions and high dimensional stability, ensuring consistent performance in both liquid and gas applications.
With standard media grades ranging from 0.3 to 100 μm and diameters up to 450mm, they provide a robust solution for corrosive environments and high-temperature processes. CMI tubes are crafted from premium alloys including 316L Stainless Steel, Titanium, Hastelloy, and Inconel, making them highly resistant to chemical attack. These tubes are easily cleaned and back-flushed, offering a long service life for critical tasks such as catalyst retention, process steam filtration, and gas-liquid sparging. Whether for pharmaceutical flow control or petrochemical dewatering, CMI provides fully customizable lengths, diameters, and tolerances to meet your exact filtration requirements.
CMI porous metal tubes are designed for industrial applications requiring stable permeability, reliable filtration efficiency, high mechanical strength, and excellent corrosion resistance.
Manufactured through advanced powder sintering technology, these porous tubes feature a uniform and interconnected pore structure that provides consistent flow characteristics and dependable filtration performance under demanding operating conditions.
Tube dimensions, wall thickness, pore size, and alloy materials can all be customized to meet different process requirements including temperature resistance, pressure conditions, chemical compatibility, and flow capacity.
These porous metal tubes are widely used in chemical processing, pharmaceutical production, gas distribution, instrumentation systems, food processing, and industrial sparging applications.
