Water Well Sand Screens
The continuous-slot wire wrapped screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry.
Our continuous-slot wire wrapped screen is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.
Slot opening for continuous-slot wire wrapped screen are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings.
Material: Mainly high-manganese steel wire, stainless steel wire, steel wire and so on.
Wedge Wire dimensions: the shape of the strip can be long rectangle, short rectangle, and trapezoid. The most common is trapezoidal. Common Size ( W × H ): 1.5 × 2.2mm, 1.5 × 2.5mm, 2.3 × 3.6mm, 1.8 × 4.3mm, 3.0 × 4.7mm and so on.
Slot dimensions: Referring to the spacing between the two strips , usually:0.1-5 .0 mm.
