Spiral Style Bridge Slotted Screen
Product Description
Spiral Style Bridge Slot Screen
The Spiral style Bridge slot screen is a kind of spiral screen pipe, which has the bridge shape slot. It’s welded by the double-side automatic submerged arc welding technology. Compared with the traditional Bridge, slot screen welding line is more full and even more reasonable in design and with a unique structure, more sophisticated and with a reliable quality. The compression resistance of the screen is much higher than the traditional one’s. The screen is the ideal substitute product of modern drilling industry which is also applied in hydro-geologic prospecting, well drilling, shaft sinking, reservoir precipitation , foundation dig precipitation ,mining & mineral processing, geothermal exploitation, mineral water supply, metallurgical geology, refining& petrochemical, geothermal air-conditioner, broken well remediation, underground water lifting, agricultural transformation, city water supply, etc.
Advantages of Slot Screen:
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
