Wire Wrap Jonson Screen is of the continuous slot, designed to provide maximum open area to reduce entrance velocity, increase hydraulic efficiency and promote more effective development. Both the inner and outer screens shall be constructed of V-shaped wire continuously wrapped around an array of equally spaced support rods of the same material. Each junction of wire/rod contact shall be resistance welded.

• Material: stainless steel 302, 304, 316, 304L, 316L or low carbon galvanized
• O.D.: 4, 6, 8, 10, 12 inch and as request
• Slot: 0.1mm - 35mm
• Discrepancy: + / - 0.05mm
• Length: 50mm-6000mm
• End Connection: welded rings or thread couplings (male / female)
• Specification of the wrap wire: 1*2mm, 2*3mm, 2.2*3.5mm, 3*4.6mm and so on
• Specification of the rod: 2.8mm, 3.0mm, 3.8mm, 4.0mm, 4.2mm, 4.5mm, 5.0mm and so on
• Special specification can be made according to your need

• Not easy to jam: The special V shaped wire makes the hole of screen outside face smaller than inside, so the hole is not easy to jam
• Slot even: The CNC machine tools strictly control the gap between the wire, so that the gap is even
• Strong corrosion resistance: Stainless steel 304 has high corrosion resistance

Wire wrap screen pipe 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
