Low Carbon Galvanized Johnson Wire Wrapped Screen Pipe
Johnson Wire Wrapped screen pipes are manufactured by a v
or wedge shaped wire around an internal array of longitudinal
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.
