Bridge filter bridge hole - shaped filter equipment sheet metal mesh filter
This kind of screen are punched precisely in a flat sheet which then is rolled into a pipe. The sand and gravel can't easily block the slot because of the special bridge style design, and Bridge Slot Screens has great mechanical strength and water entering capacity. Meanwhile, Bridge Slot Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating.
Technical Advantage
1. The bridge-shaped hole structure makes the gravel difficult to block the perforation and has strong water permeability.
2. Bridge hole structure can enhance the mechanical strength;
3 can be coated anti-corrosion materials, improve well life;
4. Product length, thickness, diameter custom, light weight;
Applications
Used in hydrogeological exploration, drilling, geological precipitation, geothermal utilization, mineral development, mining, petrochemical and other fields.
