Make durable and finest filter by using sintered mesh

sintered mesh

Sintered woven wire mesh is used in various filtration applications in the chemical and petrochemical industries. This mesh is also used in pharmaceutics and water conditioning. Sintered woven wire mesh has multi-layers of woven wire mesh laminated together by use of ‘sintering’. This creates a big class of new materials with a wide variety of mechanical properties. It is possible to design materials with specific target thickness, pore size, permeability and mechanical strength. Some layers are used for protecting & reinforcing and others for high precision filtration. The end product has high strength. There is no need of inner support for making filter elements, cleaning is easy and long working life is possible. Layer composition or outline size is available as per various customer requirements.

Sintered metal media are suitable for the most demanding industrial applications where long life is needed and often other media are expensive. For example, filtration technology utilizing sintered metal media provides excellent performance in numerous liquid/solids and gas/solid separation applications found in the handling and processing of fluids containing radioactive materials. Various types of filter media ranging from single use (disposable) to semi-permanent, are utilized for separation of particulate matter. However, semi-permanent media are usually cleanable both online & offline and are intended for sustainable, often multi-year, operating life in harsh environments. These harsh environments which may involve corrosive fluids, high pressures, high temperatures or pressure spikes, often requiring continuous filtration service, are suitable for all-metal filtration systems employing semi-permanent sintered metal media.

Sintered metal media, usually fabricated into tubular metal elements, have proven high particle removal efficiency and demonstrated reliability that uniquely afford excellent performance for demanding liquid/solids and gas/solids separation processes. The filter element and, in some cases, the entire filter are weldable, therefore, the inherent sealing eliminates the need for potentially problematic seals. These media provides a positive barrier to ensure particulate removal to protect downstream equipment for product separation and to meet health, safety and environmental regulations. Applications of Sintered metal media are

  • Gas and liquid filter systems are used in various nuclear and radioactive waste processing applications.
  • All-metal High Efficiency Particulate Air (HEPA) filter developed under Department of Energy (DOE) funding as an alternative to traditional HEPA filters fabricated with conventional glass fibers used on high Level Waste (HLW) tank ventilation systems at various nuclear sites in the US.
  • Smaller flow rate in-line gas filters utilized in compressed gas lines, vent lines, utility lines and gas sampling lines typically found in laboratory and small pilot test systems using radioactive materials. These filter examples employ a wide range of filtration technology, e.g., large scale cross-flow filtration system for the concentrating of liquid waste, in-situ back-pulse cleanable gas filtration system primarily utilizing surface particle filtration, and smaller in-line gas filter utilizing particle removal via depth filtration.

Various types of filter media made from sintered wire mesh ranging from single use (disposable) to semi-permanent are utilized today for separation of particulate matter. These media include fiber (cellulosic, polymeric and glass), ceramic, metal mesh, fabric, polymeric membrane and sintered metal media (powder and fiber).
