Galvanized Bridge slotted screen is also called flower tube, it has the bridge 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.
Regarded as the best choice of well tube filter, they are widely applied in a variety of fields in the developed countries.
According to our after – sale services and the application experience at home and abroad, the advantages of bridge slot screens,
when compared with other kinds of screen, 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 mechanical strength.
Application of anticorrosive coating will prolong the span life of wells.
Slots and the diameter of bridge slot screens can be custom make to satisfy your needs.
Convenient to operate owing to various connecting methods between screens.
