Product Description
What is spiral bridge type well screen pipe?
Bridge slot screens have 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 compared with other kinds of screens,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 probs,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 slot of screens help improving their mechanic strength.
Applications of Anticorrosive coasting will prolong the span life 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
The feature:
The slots of this kind of screen are punched precisely in a flat sheet which then is rolled into a pipe. The sand and gravel can't easily block the slot because of the special bridge style design, and Bridge Slot Screens has great mechanical strength and water entering capacity. Meanwhile, Bridge Slot Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating.
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) Formations with large particle sizes
4) Large diameter wells
5) Low to medium flow rates

Advantage
1.Easily for installation and replacement
2.Different material according to environmental conditions
3.High strength through resistance to twisting, compressive, and tensile forces
4.A smooth bore that does not impede the pass
5.Low to medium flow rates
Optimum Exploitation Flow
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.
1.johnson screens
2.bridge slot screen
3.strip slot screen
Precautions when laying the screens
1.checking the intensity of screen
2.preventing screens from colliding with hard substances
3.laying screens slowly and evenly
Installation length is broadly consistent with the thickness of the aquifer , thickness more than 30m 20-30m is installed in the main aquifer; aquifer water permeability is poor, can be appropriately extended (2-3m to observation wells); diameter is determined based on the amount of water.
