Bridge Slot water Well Screen

Bridge slot 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 water well screen 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 of water well screen

• Formations with large particle sizes
• Large diameter wells
• Low to medium flow rates

Slot Sizes

• Between 0.5 mm / 0.**2 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 **4, **4L, **6, **6L & **0, for example.

Sizes (Screens can be custom made by rolling steel plates)

• Diameters from 6 5/8 in. / ND**0 to *0 in. / ND***0
• Wall thickness from 3 mm / 0.*2 in. to *0mm / 0.4 in.
• Lengths to *2 m / *0 ft.
