US Patent 7530574 Dynamic flange seal and sealing system

The present invention features a flange to flange dynamic seal and sealing system, particularly suited for use within high temperature, high pressure environments, such as a delayed coking process. The dynamic flange seal and sealing system comprises two primary elements or seals, each of which are capable of independently forming a flange seal between two flanged components or combining to create a flange seal. The flange seal created by the dynamic flange seal and sealing system is capable of being maintained in light of, or rather the sealing system adapts to, any structural or environmental changes within the connected flanges. As such, the flange seal may be a dynamic flange seal or a static flange seal or both.
