Johnson screen is manufactured by a V or wedge shaped wire around an internal array of longitudinal support rods. Each intersection point of this 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.

Advantages of Johnson screen

The Johnson Screen is composed of rod strips and V shaped wires through manufacturing on specialized welding machine. The rib strips and V shaped wires will be welded by resistance welding, has enough welding strength, equally slot gap, high corrosion resistance, large filter area, good permeability, simple structure.

Applications of Johnson screen

-- Petroleum industry. Oil filtration.

-- Water treatment industry. Desalination of seawater, treatment of industrial water and domestic water. Water softening treatment.

-- Chemical industry. End products of chemical organic solution filtration, such as acid, alkali liquid filtration, alcohol and other products filtering.

-- Hydro-geological exploration.

-- Drilling construction.

-- Geothermal development.
