Wedge-wire screen cylinders are fully welded, cylindrical filtration elements. They are constructed by continuously wrapping a V-shaped (trapezoidal) profile wire around a series of axial support rods and securing it via resistance welding. This process creates a uniform, continuous slot that is wider on the outside and narrower on the inside. These screens are primarily used within tanks, pressure vessels, and filter towers for applications such as water collection and distribution, resin retention, sand control, fluid flow distribution, and solid-liquid separation. They are widely integrated into equipment such as resin tanks, adsorption towers, water treatment filters, and distillation column internals, serving as a core cylindrical filtration component in chemical processing, water treatment, and environmental protection systems.

Typically constructed by winding wedge-shaped wire into a cylindrical, hollow tubular form.
The support structure—consisting of ribs or support rods—is welded to the wedge-shaped wire to create precise gaps.
These gaps are generally oriented longitudinally (along the length of the screen tube).
Capable of withstanding high pressures and flow rates, these screens are widely used in applications such as well operations, filtration, and separation.

Fluid filtration (e.g., water, chemical liquids, crude oil, etc.).
Solid-liquid separation and filtration of mixed fluids.
Sand control: preventing particles from entering pipelines during downhole operations.
Downhole filtration devices for fluid extraction (in deep water wells, mines, etc.).

Water treatment: Filter pipes for surface water and groundwater, and drinking water treatment.
Oil and gas: Sand-control filter pipes for underground wells.
Chemical industry: Processing of reaction product streams (e.g., filtration of media containing sand or particulates).
Mining and metallurgy: Filtration of reclaimed wastewater and mineral slurries.
Agricultural irrigation: Well pipes for farmland irrigation.
Energy sector: Filter pipes for thermal power plants and new energy projects.

Stainless steel series: 304, 304L, 316, and 316L (the most common types; offer good corrosion and wear resistance; suitable for applications such as water treatment and food & beverage processing).
Duplex stainless steel: Used in environments requiring higher corrosion resistance, such as seawater filtration.
Special alloys: Including Hastelloy and Inconel; used in high-temperature and highly corrosive environments.
Carbon steel: An economical choice for applications with low corrosion risk; requires surface anti-corrosion treatment.

Precise slot design traps solid particles, effectively preventing pipeline clogs.
Excellent resistance to pressure and corrosion (typically constructed from stainless steel, such as grades 304 or 316L).
Highly adaptable; suitable for environments with high pressure and high flow rates.
Long service life, economical, and environmentally friendly.

Standard screen pipes: Suitable for general filtration purposes.
Bridge-slotted screen pipes: Used for downhole operations.
Pre-packed screen pipes: Equipped with additional sand-control media (such as quartz sand) for more efficient sand-control filtration.
Multi-layer screen pipes: Feature a multi-layered structure, suitable for more complex, high-precision filtration requirements.
