Louver Well Screen
- Product Description:
- Louver Well Screen, also widely known as Shutter Screen, is a high-strength integral slotted pipe specially engineered for large diameter, deep, gravel envelope wells. The louvered screen adopts an integral punching forming process, ensuring extreme structural rigidity and excellent downhole durability.
- Technical Specifications:
- - Diameter range: 6.625inch – 26inch, customized large diameter available
- - Slot width: 0.5mm – 5mm according to customer demand
- - Thickness: 3mm – 10mm for different pressure grades
- - Length: 1m – 6m, extended length customizable
- - Connection type: Beveled both ends(BBE),plain ends(PE),welded rings,threaded ends(TE),flanged ends
- Material Options:
- - Carbon steel / Hot-dip galvanized steel
- - Stainless steel 304 / 316L
- - High-strength low-alloy steel(HLSA), copper-bearing steel for special corrosive environments
- Core Features & Technical Advantages:
- 1. Ultra-high Mechanical Strength
Integrated steel pipe matrix greatly improves collapse resistance, tensile strength and pressure-bearing capacity. The louver filter tube performs far better in deep wells, high-pressure aquifers and heavy
- 2. Anti-clogging & Self-cleaning Performance
The unique downward louver structure allows water to flow in smoothly while blocking most gravel and coarse sand. During pumping, backwashing and well swabbing operations, sediment will not be stuck inside the slots, maintaining stable water yield and long-term filtering efficiency.
- 3. Structural Stability & Long Service Life
No external welding wires or vulnerable parts. The reinforced punching edge prevents slot deformation, abrasion and corrosion expansion. The overall rigid structure guarantees stable filtering accuracy throughout the service period.
- 4. Smooth Internal Bore
The fully smooth inner wall facilitates pump installation, easy well development, convenient downhole maintenance and efficient swabbing operation, without flow resistance or residue accumulation.
- 5. Customizable Slot Precision & High Versatility
Slot width can be precisely customized according to formation particle size, ranging from coarse slots for gravel layers to fine slots for fine sand aquifers. Multiple slot patterns are available for different water yield requirements.
