Bridge Slotted Screen Pipes - Water Well Screen and Casing Tubes

Bridge Slotted Screen Pipes are perforated tube filters with precision-punched staggered bridge-slot openings. Bridge Slotted Filter Pipes have arched bridge-like perforations preventing media clogging while maximizing fluid intake.
Manufactured from carbon steel or stainless steel, bridge slot screens are widely used in well drilling and filtration due to high mechanical strength, optimal sand and gravel retention, lightweight construction and cost-effectiveness.

Bridge-slot screens are exceptionally suited for water well applications due to following advantages:
1, High Structural and Mechanical Stability:
Compared with standard perforated pipes, staggered bridge-slot pipe preserves the integrity of the pipe wall, provides superior resistance to compressive and torsional forces from surrounding earth and gravel packs.
2, Anti-Clogging: The arched "bridge" structure acts as a physical barrier to prevent sand, gravel, and sediment particles from wedging tightly into the slot openings. This self-cleaning feature maintains discharge capacity and reduces the risk of well failure due to sand pumping.
3, Maximum Hydraulic Efficiency: High percentage of open area ensures smooth water entry from the aquifer into the well with minimal pressure drop, optimizing overall well yield and pump efficiency.
4, Smooth Inner Bore: The interior surface of bridge slotted pipes remain completely smooth and unobstructed by protruding elements, allowing for the seamless installation and passage of pumps.
5, Durability and Corrosion Resistance: Manufactured from heavy-duty carbon steel or various grades of stainless steel, bridge slotted screen pipes can resist severe downhole corrosion and abrasive wear.
6, Application of anti-corrosive coating to the pipes will prolong the span lift of wells.
7, Cost-Effectiveness: Bridge slotted screen pipes are lighter in weight and more economical compared with specialized wedgewire well screens.
8, Customization: Customizable pipe diameters, wall thicknesses, and slot sizes can be manufactured to match site-specific water well requirements.

Structure:
Bridge slot metal sheet rolled into tubular screen as filter tube or casing pipe (jacket tube for center tube).
