Wedge wire filter element

Wedge wire filter element, also known as wire-wound screen, is welded by a "V"-shaped or wedge-shaped stainless steel wire and a stainless steel support bar.

 

The filtration accuracy is generally 25-800um. The wedge-shaped mesh filter element has the characteristics of high strength, high hardness, wear resistance and corrosion resistance, uniform gaps, good seepage properties, easy cleaning and back cleaning.

 

Due to the full-range welding process, not only the strict continuous integrity of the product is ensured, but also the ideal gap size is formed. Compared with the currently commonly used welding process in China, the fully welded wedge wire-wound screen, water filter, water cap, water distributor, resin trap and screen plate have a smooth surface, no production edges, and no burrs. , The gap is uniform and does not leak grease.

 

The smooth surface of the filter element is the filter surface, and the gaps are strips, which belong to the surface filter form. As filter elements in various forms of automatic filters (such as automatic backwashing, scraper self-cleaning, scraper self-cleaning, and suction self-cleaning filters), they are widely used in fluid filtration in various industries.

 

Wedge wire filter element parameters

 

Precision: the lowest filtration precision can reach 25μm

 

Wedge net: up to 2800 (wedge wire) x 4500 mm

 

Material: stainless steel 304, 316, 316L, Hastelloy, copper, aluminum alloy, etc.

 

Performance characteristics of Wedge wire filter element

 

1. Multi-layer sand control filter sets have high-efficiency sand control performance, which can better block formation sand particles and meet the needs of underground sand control.

 

2. Uniform filter holes, high permeability and anti-blocking performance.

 

3. Large filtration area and low flow resistance.

 

4. Excellent corrosion resistance of stainless steel material, resistance to acid, alkali, and salt corrosion, which can meet the special requirements of oil wells, and the gap will not gradually increase due to corrosion.

 

5. The multi-layer structure is welded together, which can make the filter hole stable and have a strong anti-deformation ability.

 

Application field of Wedge wire filter element

 

Wedge wire filter elements are widely used in chemical, petrochemical, beverage, pharmaceutical, biotechnology, water treatment, solid-liquid separation, etc.
