High Strength Wedge Wire Screen Tube

Name: High Strength Wedge Wire Screen Tube
Brand: AIDA
SKU: 240107260

The core of the high strength wedge wire screen tube lies in its unique wedge-shaped design. This design makes a series of tapering gaps formed inside the filter tube. These gaps act as a filter medium, which can effectively block and trap suspended solids, particulate matter and other impurities flowing through the water body.

Product Details

The high strength wedge wire screen tube, also known as profile wire screens or Johnson screens, is a specialized form of filtration and separation equipment widely used in various industries for its durability, efficiency, and versatility. The screen tube is constructed using a series of precisely formed and wrapped wedge-shaped wires around a central support rod, creating a continuous slot opening that allows fluids to pass through while trapping solids or impurities.

The core of the high strength wedge wire screen tube lies in its unique wedge-shaped design. This design makes a series of tapering gaps formed inside the filter tube. These gaps act as a filter medium, which can effectively block and trap suspended solids, particulate matter and other impurities flowing through the water body. When the water flows through these gaps, impurities are trapped, while the cleaning fluid passes smoothly, realizing the purification of the fluid. In addition, some designs allow backwashing operations, using reverse flow or mechanical vibration of the water flow to remove impurities accumulated on the filter screen, restore its filtration efficiency, and achieve continuous or periodic self-cleaning function.

Construction and Design

1. Wedge Shaped Wires. The core component of a wedge wire screen tube is the profile wire, which is shaped like a trapezoid or wedge. This design increases the strength of the wire while minimizing clogging potential and enhancing the flow rate compared to traditional mesh screens.

2. Support Structure. The wires are spirally wound around a central support rod, which provides additional stability and strength to the tube. Depending on the application, this central rod can be solid or hollow.

3. Slot Size. The size of the slots (or gaps between the wires) can vary greatly, typically ranging from microns to millimeters, to accommodate different filtration requirements. The slot size determines what particles will be retained or allowed to pass through the screen.

4. End Connections. Wedge wire screen tubes can be designed with various end connections to facilitate easy integration into existing systems. These may include flanges, threaded ends, or even custom fittings to meet specific installation needs.

Applications

The high strength wedge wire screen tubes find extensive use across multiple industries due to their adaptability and high performance:

1. Water Treatment. They are used in water wells, desalination plants, and wastewater treatment facilities for filtering out suspended solids and ensuring clean water output.

2. Oil & Gas. In the petroleum industry, they serve as sand control screens in oil wells, preventing sand and other debris from entering production tubing.

3. Food & Beverage. Food processing applications often employ wedge wire screens for juice clarification, sugar refining, and brewing processes where product purity is crucial.

4. Chemical Processing. They are utilized for filtration and separation processes in chemical plants, where resistance to corrosion and precise filtration capabilities are essential.

5. Mining & Minerals. In mineral processing, these screens help separate minerals based on particle size, contributing to efficient ore processing.

Advantages

1. High Strength & Durability. The use of sturdy materials like stainless steel makes wedge wire screens highly resistant to wear and tear, corrosion, and pressure.

2. Self-Cleaning Properties. The open slot design promotes backwashing or mechanical cleaning, allowing for continuous operation without frequent shutdowns for maintenance.

3. Low Pressure Drop. Despite their effective filtration capabilities, wedge wire screens offer relatively low resistance to fluid flow, reducing energy consumption in pumping systems.

4. Versatility. With customizable dimensions, slot sizes, and material options, they can be tailored to suit almost any filtration application.
