A 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 then seam welded. As well, there is another new craft of bridge slotted pipe here, a spiral welded bridge slot screen (SSAW). Meanwhile, there are 2 options for the bridge-type slot patterns, straight in rows and 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.
*non-plugging -- the unique structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharge capacity.
*high mechanical -- the special construction of bridge slot screens also enhances the mechanical.
*flexible custom-made -- slots size can be custom made to satisfy your needs.
*the bridge slot well screen is not only lighter in weight and lower in price but also easily operating.
wall thickness: 3mm - 10mm.
outside diameter: 89mm - 2000mm.
slot width: 0.5mm - 5mm.

Composition and Features:
It is composed of central tube, precise punched slotted screen jacket and stainless steel ring. It has characteristics such as exquisite controlled hole, high percentage of open area, strong integral strength, resistance to deformation and resistance to corrosion and high reliability etc.
Bridge slot screens enjoy many Unique Advantages when compared with other kinds of screens, and they can be listed as follows:
•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.
Slot Sizes
Between 0.5 mm / 0.002 in. and 5mm / 0.2 in., depending on the wall thickness
