Bridge Slotted Well Screen is a durable and efficient sand control filter element designed for water wells, environmental wells and similar applications. Its name originates from the unique arched, bridge-like slot design, which enhances screen pipe structural strength while maintaining effective filtration. The bridge slot pattern can prevents clogging and the high open area maximizes fluid flow while maintaining structural integrity.
Bridge Slotted Screen Pipe as anti-sand filter offers three benefits:
Durability: Arched slots minimize stress concentration, making the screen highly resistant to deformation under pressure.
Effective Sand Control: Precise slot openings and staggered pattern prevent clogging and ensure optimal fluid flow.
Long Service Life: Robust and simple design reduces wear around slot edges, enhancing longevity.
These features make bridge slotted screen tube a preferred filter component for sand control in water extraction and similar applications.
Applications
Bridge slot screens are widely used to filter coarse sand and gravel in:
We supply bridge slotted well screens and casing pipes for sand control in water wells. Casing pipes provide structural support to the wellbore while effectively filtering out sand and fine particles to ensure clean water flow.

Materials used for bridge slotted well screen
For wells containing H2S, CO2, high-Cl and other special requirements, the casing and filter tubes are made from corrosion-resistant materials. Well Screens are acid and alkali resistant and salt corrosion resistant.
