Bridge SLot Screen :
Characteristics: It’s a type of well screen with vertical slots that are formed by protruding "bridges” that are pushed outward from the well casing. The sand and gravel can not easily block the slot because of the special bridge design. It has great mechanical strength and water entering capacity. Meanwhile, it use steel punching technology and rolled in many ways, so it is light, cheap and easily operating.
We use CNC to punch, so the slot can change as your requirements. In order to give customers more convenience, we can offer any diameter screens. We also offer galvanized ones to prolong the operational life.
Advantages :
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 discharge capacity.
4).The special bridge slots of screens help improving their mechanical strength.
5).Application of anticorrosive coating will prolong the span life of wells.
6).Slots and the diameter of bridge slot screens can be custom make to satisfy your needs.
7).Convenient to operate owing to various connecting methods between screens.
8).Lighter in weight and lower in price.
