Abstract: The present disclosure provides a method for reducing ovality in pipe for joining to pipe components by using a plug coupled on an inside surface of the pipe and a sacrificial component coupled to the end of the pipe to establish a coupling interface. The plug, the sacrificial component, or a combination thereof assists in minimizing ovality changes during use of the pipe, particularly at the end of the pipe. When the pipe is to be coupled with a pipe component, the pipe and sacrificial component are separated at a different location than the coupling interface along the pipe in proximity to the plug. The plug is left coupled to the sacrificial component, and generally slidably engaged with the pipe. The plug and the sacrificial component can be removed from engagement with the pipe. The pipe and the pipe component can be coupled together.
