SS304/316 Johnson Well Screen Pipe Johnson Tube Wedge Wire Filter Mesh
Wedge wire screen Product Information
SS304/316 Johnson Well Screen Pipe, also known as Johnson Tube Wedge Wire Filter Mesh, is a premium filtration and separation product designed for water wells, oil wells, geothermal wells, environmental protection, and a wide range of industrial filtration systems. Manufactured with advanced resistance welding technology, the screen consists of precision V-shaped profile wires welded to support rods, creating continuous slot openings that provide high flow rates, accurate filtration, and outstanding mechanical strength.
The wedge wire design is one of the most efficient filtration structures available today. The V-shaped profile wires form continuous slots that are narrow on the outer surface and gradually widen toward the inside. This unique geometry minimizes clogging by preventing particles from becoming trapped within the slots, while allowing easy backwashing and self-cleaning. As a result, the screen maintains a stable flow rate, reduces maintenance frequency, and extends service life.
Manufactured from high-quality SS304 and SS316 stainless steel, the Johnson well screen pipe offers exceptional corrosion resistance, oxidation resistance, and wear resistance. SS304 is suitable for general industrial and water filtration applications, while SS316 provides superior resistance to chloride corrosion, making it ideal for seawater, chemical processing, and other aggressive environments. Additional materials such as SS316L, Duplex Stainless Steel, and special alloys are also available upon request.

Wedge wire screen Advantage
1, the mechanical strength is high and can withstand a large pressure difference;
2, the filter gap is uniform, can form a relatively uniform filter cake, which is conducive
to backwash regeneration;
3, the wedge-shaped filter gap can improve the backwash regeneration ability;
4, pressure, temperature, anti-aging, anti-corrosion, can be applied to a variety of fluids.
5, the metal wedge mesh filter core uses metal wedge wire mesh (Johnson tube) as the
filter element, which has the advantages of high mechanical strength,
high pressure difference, easy flushing and regeneration, etc. Nearly two-dimensional filter has no dead spots of particle accumulation,
and the wedge-shaped gap is reversed. The backwashing energy can be gathered
when flushing, and the backwashing effect is good
Wedge wire screen Application
The product is especially suitable for waxy oil, asphalt, diesel, beer, and high viscosity oil.
It is widely used in electric power industry, natural gas well, petrochemical industry,
chemical industry, mining, paper making, environmental protection, metallurgy, food,
sand control, Coarse filtration and fine filtration engineering for water treatment in
industries such as decoration.
