Seal assembly for connecting two pipe sections
First Claim
1. A seal assembly for connecting one section of a pipeline or conduit (T1) having an axis X--X and a spigot end (1), to a second section (T2) having an axis X--X and an end socket (2), said seal assembly comprising:
- in succession within a space defined between an outer surface of the spigot end and inner surfaces of the socket, and in a direction from an innermost base end (12) of said space towards a mouth thereof, a radially compressed gasket (G) sealingly disposed between an outer surface of the spigot end and an inner surface (11) of the socket, wherein the gasket has an internal diameter (di) equal to 0.98 Dmin, with Dmin being the minimum outer diameter of the spigot end, a metal ring (3) disposed around the spigot end and having an inner axial surface (20) abutting the gasket, and an internal split metal mating flange (4) having outer axial and outer radial surfaces (26,
24) abutting first and second internal surfaces (8,
9) on a radially inturned lip of the socket, and an inner axial surface (27) abutting an outer axial surface (23) of the ring.

Abstract
A seal assembly for axially connecting a male or spigot end 1 of a pipe T1 within a female or socket end 2 of a pipe T2 includes a radially compressed gasket G set between the outer surface of the spigot end and the inner surface of the socket, and a metal ring 3 which fits around the spigot end and bears against a lateral, inwardly facing surface 27 of an internal split metal mating flange 4, which in turn abuts internal surfaces 26, 24 on the inturned lip at the mouth of the socket. The gasket abuts the inner surface 20 of the metal ring.
