Wedge wire screen processing involves the manufacturing and fabrication techniques used to create screens made from wedge wire. Wedge wire screens are widely used in various industries for filtration, separation, and dewatering applications. The processing of wedge wire screens includes several steps, such as material selection, wire profiling, welding, and finishing.
Material Selection: The first step in wedge wire screen processing is selecting the appropriate material for the screen based on the application requirements. Common materials used for wedge wire screens include stainless steel, carbon steel, and other corrosion-resistant alloys, depending on the compatibility with the fluid or material being filtered.
Wire Profiling: In this step, individual wires are shaped into a wedge-like profile. The profiling process involves precision cutting and shaping of the wire to create V-shaped wires with accurately controlled dimensions. The shape and size of the wedges are designed to optimize the filtration or separation performance of the screen.
Welding: The profiled wires are then welded to support rods to form a continuous and rigid structure. The support rods are usually placed perpendicular to the wedge wires and provide structural integrity to the screen.
Panel Formation: The welded wedge wire elements are assembled and arranged to form screen panels. These panels can be of various shapes and sizes, depending on the specific application requirements. The panels may be rectangular, cylindrical, or customized to fit specific filtration equipment or systems.
Finishing: After panel formation, the wedge wire screens may undergo additional finishing processes. This can include surface treatments such as cleaning, deburring, or polishing to remove any sharp edges or surface imperfections. The screens may also be coated or plated to enhance corrosion resistance, improve surface characteristics, or meet specific industry standards.
