Bridge slot screen have bridge opening 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.
bridge slotted screens and casings pipe is normally used in water wells for sand controlling. It is manufactured from precision punched quality metal sheet including ST37-2 or stainless steel 304/316L. The slots are punched in a flat sheet and at the same time the sheet is rolled into a tube and welded. Slots are arranged in staggered arrangement to reduce negative effect on the screen’s strength.

Features of bridge slotted screens and casings pipe
•High strength through resistance to twisting, compressive, and tensile forces. A smooth bore that does not impede the passage of probes, tools, etc.
•The special structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharge capacity.
•The special bridge slots of screens help improving their mechanic strength.
•Application of anticorrosive coasting will prolong the span lift of wells.
•Slots and the diameter of bridge slot screens can be custom made to satisfy your needs.
•Convenient to operate owing to various connecting methods between screens.
•Lighter in weight and lower in price.
