Abstract
A method of assembling a pipe joint uses a bearing ring with closure nuts and spreader nuts. The closure nuts are used to fix the ring to a spigot, which then has a socket disposed around it. The closure nuts are loosened such that the ring expands in diameter to seat in a groove in the socket. The spreader nuts are then used to expand the ring further to be securely within the groove.
