Abstract

A compressed seal expansion joint for fluidically connecting in a sealed relationship adjacent ends of two conduits adapted for carrying fluids of varying temperatures, the expansion joint comprising telescopically arranged outer and inner pipe members adapted to be connected to each of the conduits, the outer pipe member defining an annular packing chamber opening through its inner surface for containing at least two cylindrical guide rings disposed at opposite ends of the chamber, the rings being of a generally rectangular cross section having their long faces longitudinal to the members axis and selected of an elastic and semi-plastic packing composition pressurized by tensioned hoop bands circumscribing the outer pipe member and selected to elastically deform the outer pipe member and communicate a circumferentially compressive force to the guide rings so as to create bearing and frictional loadings and seal between guide ring surfaces and the pipe member surfaces during axial and rotational relative pipe member movement.
