bridge slotted casing pipe manufacture
bridge slotted screen steel pipe have openings arranged in rows and are staggered to reduce the negative effect on the screen's strength. bridge slotted casing pipe have
openings arranged in rows are staggered to reduce the negative effect on the screen’s
strength. Typically the slots are punched in a felt 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.
Optimum Exploitation Flow
Galvanized bridge Slot Screens increase its flow to three to nine times, when compared with other kinds of screens with the same slot width, diameter and length.

3 Strip Slot Screen
Advantage
1.High strength through resistance to twisting, compressive, and tensile forces.
2.A smooth bore that does not impede the passage of probes, tools, etc.
3.The special structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharg capacity.
4.The special bridge slot of screens helps improving their mechanic strength.
5.Application of Anticorrosive coasting will prolong the span life of wells.
6.Slots and the diameter of bridge slot screens can be custom made to satisfy your needs.
7.Convenient to operate owing to various connecting methods between screens.
8.Lighter in weight and lower in price.
9.Reduce the life safety during the installation process
