Galvanized Low Carbon Steel 12 " O.D 325 Johnson Water Well Screen Pipe
Product Description:
Johnson water well screen pipe are of the continuous slot,designed to provide maximum open are 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.The wrapped wire is V shape, and the support rod is O shape. Filter from outside to inside.
