Woven Wire Cloth
The right weaving loom for each specification guarantee the most suitable Woven Wire Cloth for every demand.
From wires as thick as 0.5mm dia., down to those finer than a human hair of only 0.025mm dia. (25 microns), we weave all materials such as Stainless Steel, Copper, Brass, Phosphor - Bronze, Nickel, Monel, Silver, and Plastics. The product can be supplied in the form of : rolls, pieces, strips, discs, fabricated parts, filters, and screen sections to suit your requirements in small or large quantities. Filter Discs are largely used for the production of polyester fibers. Our filters combine long service life with excellent service properties. |

Formulas and Symbols for Wire Cloth
w = width of aperture in mm d = diameter of wire in mm p = pitch = w + d a0 = free open area = w^2 / p X 100 |
Mesh = Number of Apertures per English inch = 25.4/p Nr./cm = Number of Apertures per cm = 10/p M/cm^2 = Number of Openings per cm^2 = (10/p)^2 Today Wire Cloth is determined by clear apertures and wire diameters. Formerly it was termed by "No." or "Mesh" which is the number of openings in a linear inch. |

Post Weaving Fabrications
Calendering : The calendering process involves the wire cloth being passed through two steel rollers to achieve a specified
reduction on the overall thickness. The some extent the wire cloth is also stabilized and lies flat, thereby being more
easily processed than regular wire cloth.
Strip Cutting : Wire cloth can be cut into strips down to a few millimeters in width. Depending on the type of cloth, lengths of 30 feet
to 650 feet can be supplied.
Edges : Wire cloth in rolls has either woven edges or cut edges, depending on whether it is woven conventionally with a shuttle or
on a shuttleless loom.

Calculation for Weight of Wire Mesh
d = mm = Wire Diameter
p = mm = Pitch (w + d) G = kg/m^2 = Mass per Unit Area Mesh = 25.4/p = Number of Apertures per inch |
G = (mesh x d^2)/2 |
Demister Pad
A Demister Pad offers a highly efficient method of separating liquid droplets from vapour. The droplets impinge on the wire filaments and are retained until they coalesce and fall down, and the free vapour passes through the apertures of the mesh. Demisters are widely used for such Gas-Liquid Separations and Desalination Plants all over the world. HAST has been fortunate in supplying to a number of such plants with encouraging results.

Knitmesh
Knitmesh is an efficient packing material for distillation columns which operate under vacuum at atmospheric pressures. The mesh disperses the liquid in a thin film and prevents "dry" surfaces and channeling which occurs in less efficient packing. Multifilament meshes give the best results due to their capillary action. Free volume of up to 95% can be achieved with filament surface areas of up to 1600 m^2/m^3 achieving higher efficiency and better liquid hold ups,
