Media Support Grids fabricated with wedge wire are superior screens for retaining media in vessels of all types, i.e. molecular sieves, de-sulfurizers, sand filters, and hydro-treaters.
In comparison with wire mesh and perforated metal, wedge wire continuous slot screens have more open area, have very precise openings, are stronger and more durable, are virtually non-clogging and reduce media abrasion. Wire mesh and grating may be less expensive initially, but wedge wire screens offer easier installation and long-term operating and cost benefits.
Wedge wire grids have maximum design flexibility, can be constructed in a wide variety of shapes and sizes from a variety of corrosion resistant alloys such as type 304, 316, 316L, 321, and 410S stainless steels, as well as nickel alloys such as C-276. Any process or vessel requirements can be accommodated, such as vertical or horizontal vessels, chordal or pie-shaped screen segments, with or without manway or other ports in the screens.
