Claim 0:
1. A flanged joint, comprising:
a first flange member having a first flat sealing surface, the first flat sealing surface extending from a radial inward edge of the first flange member to a radially outermost edge of the first flange member;
a second flange member having a second flat sealing surface, the second flat sealing surface extending from a radial inward edge of the second flange member to a radially outermost edge of the second flange member;
a hollow-metal gasket between the first flange member and the second flange member, wherein the hollow metal gasket includes a material that is chemically resistant to an alkali-metal and an inert metal coating; and wherein the hollow-metal gasket is a hollow metal O-ring; and
a spacer between the first flat sealing surface of the first flange member and the second flat sealing surface of the second flange member, the spacer defining a minimum distance between the first flange member and the second flange member, wherein:
the first flange member includes a first plurality of fastener openings, the second flange member includes a second plurality of fastener openings, wherein each fastener opening of the first plurality of fastener openings faces a fastener opening of the second plurality of fastener openings,
the flange joint comprises a plurality of fasteners for pressing the first flange member and the second flange member towards each other, wherein each fastener is disposed in a fastener opening of the first plurality of fastener openings and in a fastener opening of the second plurality of fastener openings, and
the plurality of fasteners are in contact with an exterior surface of the spacer.
