Abstract
A pipe belling process where a heated thermoplastic pipe end is forced over a sealing gasket on a forming mandrel, with the pipe being subsequently cooled to retain the gasket in an internal groove simultaneously formed in the pipe end. The sealing gasket is a two-component gasket with an elastic component and a plastic component. The elastic component is stretched over a portion of the plastic component during assembly with the plastic component acting as a belling ramp for the gasket during the subsequent pipe belling operation.
