Product introduction

Water Well Screens consist of V-shape profile wire and the longitudinal support rods.  theV  wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.  so Water Well Screens has sturdy constriction and good mechanical property.
The V-shape section plane can avoid blockage and make sure of the unimpeded water. The consecutive slot have more open area, and it can reduce the speed of the water entering to avoid the sand entering the Water Well Screens under the great pressure, so it can filter sand better. Meanwhile, the slot of Water Well Screens can change according to the real condition of the earth.

1.Stangard contruction
2.Axial wire construction
3.Internal circumferential wire construction
4.inverwire construction


Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime. 
Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing. 
Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media. 
Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP) 
Long live: Welded at each intersection creating a strong and durable screen. 
Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components. 
Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.
