Abstract
A pipe assembly includes a first pipe section having a first end and a second end, a second pipe section having a first end and a second end, and an internal collar adapted for internal engagement with both the first end of the first pipe section and the second end of the second pipe section. The collar thereby locates the first and second pipe sections in end-to-end relationship at a joint to form a composite pipe. A method of forming a pipe assembly including the steps of: forming a first pipe section having a first end and a second end; forming a second pipe section having a first end and a second end; and forming an internal collar is provided. The method further includes the step of effecting simultaneous internal engagement of the collar with the first end of the first pipe section and the second end of the second pipe section; whereby the collar locates and retains the first and second pipe sections in end-to-end relationship to form a composite pipe.
