Features and Uses
All you need to know about Micronic Wire Mesh
TWP INC offers precisely woven Dutch weave stainless steel filter cloth. These Dutch weaves (TDW and PDW) are thick meshes with small curved tunnel shaped openings. Light doesn’t pass well through these meshes.
Examples of Uses
- Hydraulic fluid filters - use TDW and PDW weave types
- Gas diffusers - use TDW and PDW weave types single layer or stacked
- Breather vents
if you need non-fraying micronic meshes, please see sintered section.
Micronic Wire Mesh - Cutting
Micronic wire meshes are easily cut with sharp hand tools. Choose your metal, weave type and opening size
Alloy Type 304 or Type 316
T304 is the basic stainless alloy, and unless otherwise specified it is assumed that this type is acceptable. Also called 18-8 due to 18% chromium and 8% nickel. T304 melts at 2600 degrees F (1430 C) but its maximum recommended temperature for continuous service is 1450 degrees F. (790 C) and is useful for intermediate service up to 1650 degrees F (900 C). Its' uses include: sorting and screening of abrasives, liquids, powders and other solids.
T316 is a special stainless alloy due to the addition of 2% molybdenum. This increases its resistance to corrosion by salts, acids and seawater. Also called 18-10 due to 18% chromium and 10% nickel. T316 melts at 2500 degrees F (1375 C) but its maximum recommended temperature for continuous service is 1500 degrees F. (815 C) and is useful for intermediate service up to 1650 degrees F (900 C). Its' uses include: processing of oils, chemicals, food and pharmaceuticals.
In general, T316 can always be substituted for T304.
Micronic (Dutch Weaves PDW and TDW)- The dutch weaves (PDW, TDW) are thick, strong; light-tight meshes which are used primarily in fluid, vacuum, and pressure filtration of liquids and gases. These are woven to precise tolerances and their openings are actually tiny curved, triangular tunnels.
Absolute Filtration Rating - A measure of retention, expressed in microns, that specifies the equivalent diameter of the smallest particle from which the filter has a retention of 100%. In actual practice, most manufacturers assign absolute ratings on the basis of retention in the range from 98% - 99.999999%. * *Nominal Filter Rating* - A measure of retention, expressed in microns, that specifies the equivalent diameter of the smallest particle for which the filter has a retention somewhere in the range of 60-90%. Nominal filter rating is imprecise.
