Wedge Wire Screen Pipe
Wedge Wire Screens are used through out the world for water, oil and gas wells, and for environmental well completions. It is the dominant screen type used in the water-well industry. This type of screen is constructed by winding cold-rolled triangular -shaped wire around a circular array of longitudinal rods. The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight. Wedge wire screen is also well known as continuous-slot wire-wrap screen, Johnson screen, v wire screen.
