sintered porous metal tube

Product Introduction​​​​​​​

The Sintered Porous Metal Tube is a high-performance filtration component meticulously engineered for demanding industrial applications requiring precise solid–liquid and solid–gas separation. Manufactured from premium metal powders without the use of binders, the tube is formed through cold isostatic pressing and sintered under high-temperature vacuum conditions. This process produces a robust, seamless structure with uniform porosity, consistent pore size distribution, and high mechanical strength, ensuring stable performance under extreme operating conditions.

Available in a wide range of corrosion-resistant alloys, including stainless steel, nickel, titanium, Monel, Inconel, and Hastelloy B, C, and X, these tubes can withstand aggressive chemicals, high temperatures, and mechanical stress. Pore sizes are precisely adjustable from 0.22 μm to 100 μm, while porosity and permeability can be tailored by selecting specific powder particle sizes and sintering parameters. This ensures optimal filtration efficiency, dirt-holding capacity, and minimal pressure drop for each application.

Dimensionally, sintered porous metal tubes are highly versatile. Outer diameters range from 10 mm to 200 mm, with customizable lengths to meet system-specific requirements. Multiple end connections are available, including DOE, 215, 222, 226, threaded types (NPT, BSP, G, M, R), flanges, rods, and quick-access ports, providing seamless integration into filtration housings or process equipment. Gasket materials, including PTFE, Viton, silicone, EPDM, and NBR, ensure chemical compatibility and leak-proof operation.

Functionally, these tubes achieve micron-level filtration, separating solid particles and gaseous impurities from liquids and gases. Their high compressive strength allows backwashing or reverse-pressure cleaning once a filter cake forms, enabling repeated reuse and extending operational life. Sintered porous metal tubes operate continuously at temperatures up to 900°C, maintaining structural integrity and filtration precision in extreme thermal and chemical environments. Applications include catalyst recovery, fluidized bed filtration, powder processing, gas homogenization, pneumatic conveying, beverage and food filtration, sensor protection, and safety-critical systems handling flammable fluids, where flame arresting and explosion prevention are essential.

With exceptional mechanical durability, thermal stability, and chemical resistance, sintered porous metal tubes offer reliable, high-precision filtration solutions for the most demanding industrial processes.
