Flanged pipe joints of three kinds are described in which no loosening or leakage can take place owing to thermal expansion, even if different materials, e.g., steel and graphite, are used for the two pipes being cennected and the bolts used to clamp the flanges together. The first joint is comprised of two flanged pipes so constructed that the plane where the bolt head contacts its flange coincides with the sealing plane. In the second joint, the seal is maintained by rings surrounding the bolts that exert pressure on the sealing plane should differential expansion occur; the rings, bolts, and one pipe is steel, whereas the other pipe can be graphite. The third joint is comprised of pipes having sectional 60 deg flanges and 60 deg gaps so that the flanges interleave. Assuming a uniform temperature throughout the joints, radial, but not axial, movement of the pipe end faces is allowed. (D.L.C.)
