Abstract
In an example, a raised face flange assembly, comprises an upper flange to couple to a lower flange using one or more bolts: wherein the upper flange or the lower flange comprises: a bolting face defining one or more openings for the one or more bolts, respectively; a pair of raised faces including a first raised face and a second raised face to make contact with a mating surface of the other of the upper flange or the lower flange; wherein a distance between an area of the second raised face and a plane corresponding to the bolting face is greater than a distance between an area of the first raised face and the plane to distribute contact force with a mating surface over the area of the second raised face to maintain a seal.

A raised face flange, comprising:
- a bolting face defining one or more openings for one or more bolts, respectively;
- a pair of raised faces including a first raised face disposed in a first plane and a second raised face to form a seal in a nuclear reactor module, the second raised face disposed in a second plane that is different than the first plane;
- wherein the bolting face is disposed in a third plane that is different than the first and second planes;
- and
- wherein a distance between an area of the second raised face and the third plane is greater than a distance between the first plane and the third plane to distribute contact force with a mating flange over the area of the second raised face to maintain the seal.
A vessel of a nuclear reactor module, the vessel comprising:
- a vessel flange joint to couple a first cylindrical sidewall of the vessel to a second sidewall of the vessel;
- the vessel flange joint including an upper flange coupled to lower flange using one or more bolts, wherein the upper flange or the lower flange includes:
- a bolting face defining one or more openings for the one or more bolts, respectively;
- a pair of raised faces including a first raised face and a second raised face to make contact with a mating surface of the other of the upper flange or the lower flange;
- and
- wherein a distance between an area of the second raised face and a plane corresponding to the bolting face is greater than a distance between an area of the first raised face and the third plane to distribute contact force with a mating flange over the area of the second raised face to optimize a seal of the vessel flange joint.
A raised face flange assembly, comprising:
- an upper flange to couple to a lower flange using one or more bolts:
- wherein the upper flange or the lower flange comprises:
- a bolting face defining one or more openings for the one or more bolts, respectively;
- a pair of raised faces including a first raised face and a second raised face to make contact with a mating surface of the other of the upper flange or the lower flange;
- and
- wherein a distance between an area of the second raised face and a plane corresponding to the bolting face is greater than a distance between an area of the first raised face and the plane to distribute contact force with a mating surface over the area of the second raised face to maintain a seal.
