Continuous Slot Stainless Steel Johnson Well Screen Casings

Product introduction

Water Well Screens consist of V-shape profile wire and the longitudinal support rods.  the V  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 a 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.

welded cylindrical screen

The  construction corresponds with the following drawings respectively

1. Standard construction

2. Axial wire construction

3. Internal circumferential wire construction

4. underwire construction

Advantages

l Production process continuity: V-shaped profile wires creating slots that enlarge inwardly and therefore avoid clogging and minimize downtime. 

l Low maintenance costs: Separation at the screen surface which can easily be cleaned by scraping or backwashing. 

l Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media. 

l Low operational costs: Large open area with an effective flow, high yield and a low-pressure drop (DP) 

l Long live: Welded at each intersection creating a strong and durable screen. 

l Reduced installation costs: supporting constructions eliminating costly support media and enabling maximum flexibility in the design of components. 

l Chemical and thermal resistant: A variety of corrosion-resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.

Technical parameter

The V-shaped wire can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions require these variations in a screen's construction.
