haixing judy   Bridge slot 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 this type of 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

• 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.
