Porous Sintered Metal

Van Borselen supplies a wide range of porous sintered metal products in a broad range of materials such as Stainless Steel, Bronze, Hastelloy C276, Hastelloy X, Hastelloy C22, Inconel 600, Monel 400, Nickel, Titanium and more.

Discs

Porous Metal Discs are used as filters, frits, snubbers, aerators, or as base components or assemblies.

Available in diameters from as small as 0.020 inches to over 8 inches with a wide range of thickness.

Cups and Bushings

Porous sintered metal cups and bushings provide additional porous surface area for longer filter service life or for increased permeability when compared to porous sintered metal discs of the same diameter.

For the best pore size uniformity and quality, porous sintered cups and bushings are recommended when the length to diameter ratio is less than 3:1.

Seamless Tubes

For porous sintered metal components requiring a large amount of surface area and length to diameter ratios greater than 3:1, porous seamless tubes are the best option to achieve the optimum pore size and density uniformity.

Porous Seamless Tubes are manufactured by Cold Isostatic Pressing utilizing specially designed tooling.

Available up to 1 meter in length (Seamless)

Spargers

Sparging and Gas-Liquid contacting applications utilize gas flowing through a network of fine pores to produce small uniform bubbles that result in high efficiency contact between a gas and a liquid.

Normally, 0.5, 2 or 10 Micron Grade porous sintered metal materials are used to produce fine bubbles while preventing the flow of liquid from penetrating back into the pores at lower internal pressures.

Flow Restrictors and Vents

Porous sintered Metal Flow Restrictors are used in Analytical and Process Instruments as calibrated leaks, timing devices, fuses, vents, breathers, and fluid metering devices.

Gas flowing through a Porous Sintered Metal Flow Restrictors results in a Laminar flow that can control the gas flow more accurately and more reliably than other volumetric flow limiting products such as orifices and metering valves.

Flame Arrestors

Sintered Metal Flame Arrestors are used in many process instrument and analytical instrument applications as safety devices for handling combustible gases for gas analyzers.

By preventing the gas from burning back into the device and exploding, damage to the equipment or injury to an operator can be avoided.
