<p>There is disclosed a pipe joint, and a method of forming a pipe joint, between two metallic pipes which have been internally and/or externally coated with a material to prevent corrosion. The joint includes a spigot and a socket, the socket having, or being formed with, an internal circumferential groove (6) that provides a seating for an elastomeric sealing ring (8), and forwardly of which groove an extension or lip (13) is provided which provides a welding location (14) remote from the sealing ring. The coating on the end of the socket if necessary is removed to facilitate welding, and the spigot has a heat sink member (9) to enable the lip of the socket to be welded to the metal of the spigot.</p> |
