219.1 mm Stainless steel 316 water well screen have two types. One type consists of two layers wedge wire screens and the middle filter. The other type consist of perforated base pipe or slotted API casing pipe and outer screen jacket. The base pipe can be stainless steel or carbon steel API 5CT casing. Having the API casing inside a wire wrap screen jacket is supporting the screen and enhance the capabilities and high tensile strength Loads. Base pipe can be made from API pipe seamless casing spiral or stainless steel casing. Opening area for the base pipe is up to 15% and for the jacket is up to 30%. Johnson type jacket slot size is between 0.15mm to 3mm.
- The V-shape section plane of Wedge wire screen pipe (Johnson screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
- The consecutive slot of Wedge wire screen pipe (Johnson screens) have wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase the water yield and prolong service time of the well.
- Wire and support rods are all-welded, which makes the Wedge wire screen pipe (Johnson screens) more robust and longer life.
- The longitudinal support rods and the continuous slot make the Wedge wire screen pipe (Johnson screens) have more excellent pressure-resistant performance.
- Specifications and end connections of Wedge wire screen pipe (Johnson screens) can be fabricated according to customers' requirements.
