TECHNICAL CATALOGUE_Gaskets
Most of the chemical processing equipment such as towers, columns , filter housings, heat exchangers, utilize plates or trays.
These plates are subjected to loads such as: thermal, corrosion, pressure, weight which can develop dramatically while in use and act constantly to deform the plate.
Very few construction materials can withstand these loads, among them one can find Stainless-steel, Exotic alloys, ceramics, Graphite and glass lined.
Until today, fluoropolymers were dismissed from the construction materials list due to their tendency to deform under mechanical loads at elevated temperatures. Only small diameter fluoropolymer plates can be used in the industry.
VELES GROUP introduces a pioneered solution for the above: if steel is strong enough and fluoropolymers are inert enough , why shouldn’t we combine them both into a rigid corrosion free plate / tray?!
- VELES GROUP‘s plates are not coated with thin layers.
- VELES GROUP‘s plates don’t have welds or seam.
