Compared with other Ordinary pipes
 
1. V wire wrap water well screen with high open area are more suitable 
for the construction of high-quality water wells, oil wells and gas wells. 
 
2.Low cost operation V wire wrap water well Screen with high open area shall favor 
groundwater infiltration. Abundant water shall reduce the water levels down, 
thus to save energy consumption.
 
3. Reduce the abrasion of the pump  
 
4. Extend the life span of wells
