Commonly referred to as continuous slot or wire wrap screen, this product was originally developed to overcome problems associated with cable tool wells drilled in fine grained, uniform sands in the North Central United States. These wells were typically completed in relatively shallow, thin aquifers that were very prolific in terms of water production. Continuous wire wrap screen are very effective in wells of this type since they can be manufactured with very small slot size and yet still maintain the necessary open area to minimize frictional head loss.
Continuous wire wrap screen is manufactured by wrapping a shaped wire around an internal array of longitudinal rods and are joined by resistance welding. Screen sections are usually twenty feet long. Most continuous wire wrap screen is manufactured from stainless steel rather than carbon steel in order to avoid problems which often lead to accelerated corrosion.
