The Johnson Specialty Screen pipe is made up of rods and wrap wire. The rod can be round wire, triangular wire or trapezoid wire. The wrap wire is triangular wire (Vee wire).
The Johnson Specialty Screen pipe has a delicate structure and high open area, as well as accurate slot dimension. At the same time, it has characteristics of heat-resisting, anti-corrosive, good machine capability, long service life, safety and reliability and so on. It can be used in many kinds of medium filtering. Such as oil, chemical acid, the alkali liquid filters, the ethyl alcohol, etc.

Other Speical Types
90° Reverse rolled screen pipe
Slot direction is axial and filtering direction is from the inside towards outside(FITO). Smooth surface is at the inside and supporting rods are at the outside.
Longitudinal Reverse rolled screen pipe
Slot direction is vertical and filtering direction is from the inside towards outside(FITO). Smooth surface is at the inside andsupporting rods are at the outside and longitudinal.
Inverted profiles screen pipe
Slot direction is vertical and filtering direction is from the inside towards outside(FITO). Smooth surface is at the inside andsupporting rods are at the inside and longitudinal.
The Continuous slot screens are made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods. Each jointpoint 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. Therefore the screen allows water or oil to enter the well freely in ample quantities while keeps the majority of sand and gravel out of the well at the same time.
