The common wire diameters of knitted mesh used for insulating blankets are .008″, .00095″, and .011″.Where greater strength is needed because of frequent removal such as turbines or stress relieving blankets, .011” is used. For less frequent remove, .008″ is used. For applications which involve temperature extremes such as furnaces, the .011″ diameter is recommended to reduce the weakening caused by oxidation or furnace atmosphere conditions.
The common density (openings/inch) used is 60, as knitted mesh provides the optimum balance between large openings for economy, yet small enough openings to prevent tufting. 76 density is also available.
Yield listed is for single ply. Knitted mesh is tubular in construction (double-ply) and is typically cut open by the user and installed as a single ply.
Insulating blanket knitted mesh is made in widths of two-ply stocking from 1″ to 43″. However, most applications use widths of 12″, 18″, 24″, 30″, or 42″.
SS knitted mesh can be fabricated from practically any ductile metal—most commonly 304SS, as well as Monel and 309SS, where equipment will be subjected to corrosive environments—or knitted as a metal-synthetic composite.
