Johnson Type Casing Pipe Wound Screen For Water Well Oil Well Filter
Water well screen is welded by V wire and support rod.There is a fixed value slot between each v wire, and the continuous slot, designed to provide maximum open are to reduce entrance velocity, increase hydraulic efficiency and promote more effective development. The wrapped wire is V shape, and the support rod is O shape. Filter from outside to inside.
Filter out the impurities and suspended matter in the water to ensure that the water is clean and sanitary and will not cause blockage. Screens are typically made of fine-mesh stainless steel mesh that effectively removes sediment, sediment, and other small particles from the water. The design and placement of wire-wound screens can be adjusted to ensure a balance between water flow and filtration.
Special specification can be made according to your need!
Not easy to jam
the special V shaped wire, make the hole of screen outside face is smaller than inside, so the hole is not easy to jam.
The CNC machine tools strictly control the gap between the wire, so that the gap is even.
Strong corrosion resistance
Stainless steel 304 have the high corrosion resistance
Johnson Screens specific continuous-slot construction aims to optimize flow rates, minimize clogging and help develop the water-bearing geological formations faster. It is best applied in the following situations:
Geological formations comprised of small, fine particles
Water wells where gravel packs will be installed
Thin aquifers, where maximum open area is required
Large- and small-diameter deep wells
