Product Description
ASTM a53 galvanized carbon steel bridge slot screen for well drilling

ASTM a 53 Carbon Steel Bridge Slot Screen / Bridge Slotted Screen / Bridge Slot Screen
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, Water Well Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating. We use CNC to punch, so the slot can change as your requirements. In order to give customers more convenience, we can offer any diameter Bridge Slot Screens and Water Well Screens. We also offer galvanized Well Screens to prolong the operational life. 

The bridge slot screen is manufactured on a press flat sheets or plates .The slot opening is usually vertical and provides two orifices, longitudinally aligned to the axis. The perforated steel sheet ,or plates, are then fabricated into tubes, and the seam is welded .Normally ,5-ft sections of bridge slot screen are welded together into longer lengths for field installation.
 The bridge slot screen is usually installed in gravel envelope wells .Its chief advantages is a reasonably high area of opening at a relatively low cost. Since gravel control is more difficult with any vertical opening as compared with a horizontal opening ,a smaller-aperture size relative to the pack  material should be selected.

 2.A smooth bore that does not impede the passage of probes, tools, etc.
 3.The special structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharge capacity.
 4.The special bridge slot of screens helps improving their mechanic strength.
 5.Application of Anticorrosive coasting will prolong the span life of wells.
 6. Slots and the diameter of bridge slot screens can be custom made to satisfy your needs.
7.Convenient to operate owing to various connecting methods between screens.
8. Lighter in weight and lower in price.
