Stainless Steel 304 Johnson type screens Introduction
Johnson type screens are 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.
