continuous slot well screen

Johnson v wire water well screen introduction

Continuous slot well screen is manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods. Each intersecting point of these wire is fusion welded.

The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities,

while at the same time keeps the majority of sand and gravel out of the well.

Specification

Advantage of water well screen

1. Screens with high open areas are more suitable for the construction of high-quality water wells, oil wells, and gas wells.

2. Low-cost operation Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus to save energy consumption.
3. Reduce the abrasion of the pump 
Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells 
Comparatively, groundwater entering into a screen with a higher open area is much easier than entering into a lower open area screen. The slow water flow shall extend the life span of wells

Characteristics

The welded stainless steel water well screen is made up of rods and warp. The rod can be round wire, triangular wire, or trapezoid wire. The warp is a triangular wire (V-shaped wire). Water well screens have a structure and high open area, as well as an accurate slot dimension. At the same time, water well screen has heat-resisting, anti-corrosive, good machine capability, last long, safety and reliability, and so on characteristics. It can be used in many kinds of medium filtering.
