Bridge slot screen , 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.
