Water Well Screens are manufactured by wrapping a shaped wire around an internal array of longitudinal rods. The wire and rod, generally made from carbon or stainless steel are joined by resistance welding. Screen sections are usually twenty feet long. The ‘V’ or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous and consistent slot opening. Most continuous wire wrap screens are manufactured from stainless steel in order to avoid problems associated with sand pumping that may result from accelerated corrosion of carbon steel screens.
