Bridge Slot Screens/Water Well Screens
Bridge slot screens/Water Well Screens have openings arranged in rows and are staggered to reduce the negative effect on the screen's strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded.
Advantages offered by Bridge Slot Screens/Water Well Screens are:
- High strength through resistance to twisting, compressive, and tensile forces
- A smooth bore that does not impede the passage of probes, tools, etc.
Applications
- Formations with large particle sizes
- Large diameter wells
- Low to medium flow rates
Slot Sizes
- Between 0.5 mm / 0.002 in. and 5mm / 0.2 in., depending on the wall thickness
Materials of Construction
- All types of steel such as carbon steel, galvanized steel, coated steel and stainless steel types 304, 304L, 316, 316L & 430, for example.
Sizes (Screens can be custom made by rolling steel plates)
- Diameters from 6 5/8 in. / ND150 to 80 in. / ND2000
- Wall thickness from 3 mm / 0.12 in. to 10mm / 0.4 in.
- Lengths to 12 m / 40 ft.
