Wedge Wire Screen Pipe

Wedge wire screen pipe is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry. Wedge wire screen pipe is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings. Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be non-clogging, are narrowest at the outer face and widen inwardly;

Advantages:

1. Long live: Welded at each intersection creating a strong and durable screen.

2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.

3. Maximum process output: Continuous-slot screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this type of screen has maximum open area. Large open area with an effective flow, high yield and a low pressure
