Patent ID: 7316762

Claim:
A delayed coking system comprising: a coke drum having at least one flange and respective sealing surfaces thereon; a component member also having a flange and a sealing surface thereon that are complimentary to said flange and said sealing surface of said coke drum, said coke drum and said component member connecting together via their respective flanges within said delayed coking system; and a high temperature, high pressure dynamic flange sealing system that seals said component member to said coke drum, said dynamic flange sealing system comprising: a bi-material gasket supported within a recess of said sealing surface of said flange of at least one of said coke drum and said component member, said bi-material gasket comprising a flexor and a flexible sealant attached thereto, wherein upon said connection of said flange of said coke drum and said flange of said component member, said flexor and said flexible sealant contact said sealing surface of said complimentary flange, and wherein said flexor is caused to contract relative to the force exerted and applied thereon, said force resulting from the pressure generated within said flanges upon connection, said flexor resultantly forcing said flexible sealant to displace against said sealing surfaces and form a seal and a flange seal between said flanges of said coke drum and said component member.
