Form:0.5mm slot stainless steel johnson type water well screens crepine johnson for water water well drilling foragesare manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods. The world advanced all-weld technology is used with each intersecting point of these wire fusion welded, which creates the robust construction and excellent mechanical performance.
