Abstract:
A connection of two pipes each including a liner. Liner sections connected to the liners are sections joined together forming a joint of the liner sections. An electrofusion coupling may overlie the joint of the liner sections and be used to fuse the joint. A collar may be positioned to overlie the joint of the liner sections. A bushing may be positioned between the joint of the liner sections and the collar. Hubs may be connected to the ends of the pipes. The liner sections and hubs may include corresponding structure which resists movement of the liner sections away from the joint of the liner sections. A connection of two pipes each including a liner may be formed according to disclosed methods.
