Porous Metal Sintered Filter Tube
Good mechanical properties,easy to shape and weld
High strength
High temperature resistance
Long service life.
Product Introduction
Metal sintered filter tubes are manufactured by compressing and sintering metal powders to form a rigid, porous structure with controlled pore size and distribution. This structure enables precise filtration of liquids and gases while maintaining high flow rates and mechanical strength.
Available in materials such as stainless steel, titanium, nickel, and bronze, these filters are engineered for high-temperature, high-pressure, and corrosive environments.
Key Features
Controlled and uniform pore structure for precise filtration
High mechanical strength and pressure resistance
Excellent corrosion and oxidation resistance
High-temperature tolerance up to 800°C
Reusable, cleanable, and long service life
Wide material and micron rating options
