Pipe Based Screen for Water Well
The pipe based screen is produced by wrapping a high precision wedge wire screen around an API compliant base pipe. The built-in pipe provides extra support to the outer wrap screen layer, which makes the pipe based screen suitable for severe environments such as high pressure, high temperatures or deviated wells.
The strength of the base pipe also allows the use of smaller wedge wires, which yields a higher open area. Horizontal support rods direct the flow to the nearest pipe perforation, and advanced welding technology creates a tighter grip between the wedge wire screen and the base pipe. These pipe based screens are used in vertical wells, and horizontals in multi-lateral deployments, where a high load bearing capacity (to prevent collapse) is required. Fittings are provided as well to satisfy most well design and installation requirements.
Features
1. A built-in base pipe provides rigid support to the outer screen, allowing the screen layer to yield partially to high water pressure without the risk of the slot opening widening. It is highly recommended for severe water well requirements.
2. The outer wrap layer features continuous slots with a precise tolerance of 0.05mm. Small slots limit the sand access.
3. Densely arranged slots provide a reduced flow resistance, allowing more water to enter the well pipe.
4. The slot openings widen inwardly, allowing water to flow at a reduced speed, which alleviates pressure felt on the pipe assembly.
5. Small diameter pipes negate the need for large diameter wells.
