Stainless Steel Filter Mesh specifications are precise geometrical structures with uniform porosity, in contrast to fibrous felts or synthetic fibers.
Woven Filter Mesh is used for separation of solids and clear liquid filtration as in the cleaning of fuels or hydraulic liquids, or in water treatment.
Woven Stainless Steel Filtration Cloth is produced in the following weave styles:
TWILL DUTCH WEAVES
 |
The finest particle size retention possible in wire cloth is achieved by utilizing Twill Dutch Weaves. The term "Twill" indicates the warp and shute (weft) wires pass alternately over two and under two wires. The term "Dutch" refers to the use of a heavier warp wire diameter in conjunction with a lighter shute wire diameter.
In a Twill Dutch Double Weave the shute wires are driven up so tightly that there is always a shute wire above and below the warp wires, creating a weave with the warp wires completely covered. The flow-pass geometry is extremely tortuous, insuring excellent particle size retention.
|
PLAIN DUTCH WEAVES
 |
Plain Dutch Weaves can accommodate high flow rates with a relatively low pressure drop. They are woven with each warp and weft (shute) wire passing over and under one wire. The shute wires are smaller in diameter than the warp wires and are driven up close together, creating a dense weave.
|
ABSOLUTE MICRON RETENTION
In both types of Dutch Weave the sum derived from multiplying the number of weft wires in a given measurement by their diameter results in theory, on a specification with no open space. Because the wires are driven together during the weaving process, the aperture size cannot be calculated in the normal manner.
There are two methods by which the aperture size can be determined:
BUBBLE POINT TEST
The pressure required to pass air bubbles through the mesh (covered by a test liquid) is measured. The average aperture size is then calculated by taking into account surface tension, liquid density, temperature and immersion depth.
GLASS BEAD TEST
A suspension containing glass beads is passed through the mesh - the diameter of the largest bead passing through is considered as the absolute micron retention.
