Wedge wire screen panels are widely used as catalyst support screens and grids for the petrochemical and refining industries.. These support grids are made from V-shaped profile wire, featuring a screen slot that is narrow at the top and wider at the bottom. This design ensures a durable structure with high strength, substantial load capacity, precise open area, and non-clogging characteristics. Additionally, the flat surface of the support grids facilitates easy installation through a manway.
Basic Principle
Support grids are removable screens with a self-supporting filtration structure. They are designed to retain active media or catalysts while allowing gas or liquid to pass through. These grids are also capable of withstanding the pressure drop over the catalyst bed throughout the entire catalyst cycle.
