WHY HEBEI DRAHTGEFLECHT KNITTED MESH CO.,LTD?

For over ten years, we have been producing and exporting monofilament, multi-filament, co-knit and multi-strand knitted wire meshes, and series processed filter products. Our products are mainly used in Oil & Gas Industries; Drilling (Oil & Water well); Petrochemical & Process Industries; Shielding, Sealing of Auto Engine Exhaust System; Air Filters, Breathers and Separators; similar high temperature applications. The knitted mesh filter products work efficiently to remove the mists and liquid droplets entrained in thermal heating filtration system. Knitted wire mesh is made of different materials including aluminum, copper, monel, Teflon, plastic, stainless steel, nickel, metal alloys as well as PP, PTFE, FRP.

Supplied forms mainly are: knitted wire mesh rolls, tubes and tapes, blankets, pad demisters, mist eliminators, compressed gaskets, breathers, shieldings, washers, mufflers and other filter elements.

Why Knitted Mesh for Thermal Filtration?

Advantage of knitted wire mesh is its unique construction. Knitting produces an interlocking-loop pattern. The final knitted mesh is in the structure of inter-connecting loops, and it similar to a long knit sock. In this configuration, each loop is an integral part of its neighbors with each supporting the other. When a mesh or mesh element is compressed, stretched or bent, and provided that exertion is not past the material's yield point, this integrity allows the element to spring back to its original form. Hence, it can work efficiently under high temperature work environment.

Our knit wire diameter is commonly range from 0.11mm to 0.35mm. But for special applications, knit wire as small as 0.03mm or as large as 0.8mm in diameter is available.

Metal wire meshes mainly serve the following industries: cleaning of the filter, plastic and die, mufflers, shock absorber mounts, soundproof generator pad, air conditioning humidifier pad, to capture the flame of the wireless signal shielding, sealing in harsh environments.

Industries Served:

Protection of Diesel fuel injections
Radio frequency interference shields
Shock absorbers (Cuhion steel), Vibrations mounts
Transfer of normally, exhausted waste heat
Mufflers of pneumatic tools.

Different Materials Offering Different Properties.

Monel knitted wire mesh has good corrosion resistance in all extreme environments and it is reasonably conductive and is tough with high tensile strength, giving good wear characteristics.

Knitted wire mesh made of tinned copper clad steel has the best shielding performance of all wires used in knitted meshes, combining low contact resistance with a small degree of permeability. It is not suitable for highly abrasive applications where the TIN plating may wear away to expose the copper. The corrosion resistance of tinned copper clad steel knitted wire mesh is suitable for most applications.

Aluminum knitted wire mesh is mechanically weak and will readily take a compression set and this combined with its readiness to form a non-conducting oxide.

Stainless steel knitted mesh is often used as a protective final layer over the other knitted mesh gasket, materials on order to provide a wear-resistant contact surface.

Factors Influencing the Work Efficiency of Mesh Type Demister Pads

Wire diameter is an important factor in manufacturing materials because it will directly affects flow, dirt holding capacity, pressure drop and cost. Knitted wire mesh demister pad is used to separate in the most efficient manner the very fine enstrained drops carried away by a gas or steam, either at a boiling stage, vacuum evaporation or bubbling of a liquid. In fact there are two phenomena, one mechanical and one physical, but no filtration at all since the size of the held drops has no realtion with the infinitely greater size of the pore or open space. The head loss or gas passage resistance is practically imperceptible, however demisting can reach up to 99% efficiency. Speed of the gas or steam is another factor that conduct influence to the efficiency of the demisters: A demister reaches the highest efficiency when the speed of a gas or steam ranges between certain limits.
