A pipe joint between two metallic pipes which have been internally and/or externally coated with a material to prevent corrosion. The pipe joint includes a spigot terminating in an inverted hump supporting an elastomeric seal wherein the inverted hump is spaced from a protruding hump. The pipe joint further includes a socket adapted to fit over the spigot, the socket having an outwardly flared forward end terminating in an annular lip that engages an exterior of the protruding hump wherein the lip is welded to an exterior of the spigot. |
