Wedge wire screens, also known as Johnson screen mesh, are a type of metal wire mesh used for sieving and filtering. They are commonly referred to as Vee wire screens, triangular wire screens, or trapezoidal wire screens, depending on the shape of their profiled wires. This versatile structure component is widely used in various industries, including screening, dehydration, and desliming operations. Due to its high strength, stiffness, and carrying capacity, it can be made into different shapes to serve as a screening filter unit. The material used for wedge wire screens varies, commonly including stainless steel (SS205B, 304, 316, etc.), low carbon galvanized wire (LCG), mild steel wire, and iron wire.
Wedge wire screens can be found in different forms, such as wedge wire tubes/pipes (also referred to as wire-wrapped stainless steel screen pipes, water and oil well screens, changeable filter elements, screen cylinders, spiral screen pipes, strainer tubes, filter circumferences, filter drums, v wire slot tubes, screen baskets, cylindrical screens, stainless steel lateral arms, hub laterals, head laterals, etc.), wedge wire nozzles (such as water filter nozzles, johnson wire screen nozzles, and stainless steel strainer nozzles), wedge wire screen plates/pieces/flat panels (including dewatering screen panels, johnson screen plates, v wire flat panels, wire-wrapped panels, sieve bends for coal, arc screen plates, vibrating screen plates, screen plates with polyurethane frames, curved screens, and wedge wire gratings), and wedge wire screen cylinders (for applications such as rotary drum screens, DSM screens, and wedge wire filter baskets). The weaving process used for wedge wire screens is full welded, ensuring a strong and durable structure. These screens have a wide range of uses, including water wells, oil wells, mining, coal, chemicals, fertilizers, food, environmental protection, sewage treatment, food filtering, salt industry netting, and more.

Inward opening slots, also known as FOTI, are specifically designed to prevent sand from becoming lodged and blocking the filtration screen. This feature ensures that the screen maintains its effectiveness for a longer period of time, without the need for frequent maintenance or replacement.
The design of these slots also allows for minimal pressure drop, while maintaining a stable flow rate. This means that the filter is able to maintain a consistent level of performance without negatively impacting the overall system.
The high efficiency of the screen ensures that the pumping process remains consistent, ultimately contributing to a longer lifespan for oil wells. This added durability not only saves time and money on maintenance, but also increases overall efficiency.
The continuous slot wedge wire used in these screens results in a greater open area compared to perforated metal pipes or slotted pipes typically used in water well applications. This means that more material can be filtered and less debris can pass through, resulting in a cleaner end product.
To add to its durability, the wedge wire screen tubes also feature sturdy longitudinal support rods, providing excellent resistance to pressure. This makes them ideal for use in a variety of industries and applications where high pressure is involved.
One of the great benefits of wedge wire screen tubes is their versatility. They can be customized to fit a specific application by selecting the appropriate tube based on the filtration accuracy and specific scenario. This makes them a suitable choice for a wide range of industries and uses.
To ensure precise filtration performance, state-of-the-art equipment is used to manufacture these screens. This results in precise slot sizes and high roundness of the screen tube, further contributing to their efficiency and effectiveness.
There are also various types of wedge wire screen tubes available, with different edge types and diameters. This allows for further customization and flexibility in choosing the right screen for a specific application.
Wedge wire screens are widely used in industries such as water treatment, oil and gas, food and beverage, mining, and more. Their versatility, durability, and efficiency make them a popular choice for meeting filtration needs in a range of industries.
Lastly, quality assurance is a top priority when it comes to manufacturing these screens. Surface pickling and passivation treatment are used to ensure that the final product is of the highest quality, meeting industry standards and exceeding customer expectations.
