How to Choose a Johnson Wedge Wire Screen?

JX Filtration June 17, 2025 Wedge Wire Screen

In industrial fields such as oil extraction, water well construction, and mine filtration, Johnson wedge wire screens are core filter elements, and their performance directly determines the efficiency and life of the entire system. Faced with a wide range of products on the market, how to make accurate choices? Master the following four key points to help you easily lock in the ideal choice.

1. Gap size: Accurately match filtration needs

The soul of the screen lies in the gap! If the gap is too large, impurities can easily penetrate and cause blockage; if the gap is too small, insufficient flux will affect efficiency. It is necessary to scientifically calculate the required gap width based on the particle size distribution of the target liquid. JX Filtration can recommend the most matching V-wire gap or trapezoidal gap size based on your media characteristics.

2. Material and strength: dual guarantee of corrosion resistance and pressure resistance

Corrosion resistance: For corrosive media such as acidic water, sulfur-containing oil and gas, 316L stainless steel or higher-grade duplex steel is preferred.
Structural strength: The welding strength of the support bar and the filter wire is crucial to ensure that it will not deform or crack under deep well high pressure or formation extrusion.

3. Filtration accuracy and flux: core indicators of high efficiency and smooth flow

The unique advantage of Johnson wedge wire screens lies in their high opening rate. The trapezoidal seam or V-wire structure design can effectively prevent particle blockage and significantly increase the flux per unit area.

4. Supplier strength: endorsement of customization capabilities and professional services

High-quality screens are not standard parts and need to be adapted to local conditions. JX Filtration can flexibly adjust the base pipe diameter, gap layout and connection method according to your well diameter, well depth and geological report.

Choosing Johnson wedge wire screens means choosing long-lasting and efficient productivity. Only by deeply examining the gap accuracy, material strength, flux performance and supplier strength can we find a filter guard that truly fits the harsh working conditions.
