Bridge slot screen features bridge-like slot, which creates a gap between the well casing and the packed gravel. Bridge slots are spaced in rows or in staggered state.Straight seam welded bridge slot screen (ERW) is manufactured on a press from flat sheets or plates. The bridge type perforated steel sheets or plates are then rolled into cylinders and the seam welded. As well as, there is another new craft of bridge slotted pipe here, spiral welded bridge slot screen (SSAW). Meanwhile, there are 2 options of the bridge type slot patterns, straight in rows and in staggered. The slots size is precise and can be changed as practical requirements. Bridge slot pipe screens usually use low carbon steel Q235, stainless steel 304, 304L, 316L. To prolong its service life, galvanized well screens are still supplied.
Bridge slot screen tube is used in projects of water well, mining & mineral processing, municipal water supply, refining & petrochemical, water treatment, architecture and construction, etc.
