US 2016/0101453 A1 · System and Method for Reducing Pipe Ovality

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.

Dependent claims

A method for reducing ovality changes in a pipe for coupling with a pipe component, the pipe having a plug inserted into a pipe end and fixedly coupled to the pipe at a coupling distance from the pipe end and the pipe further having a sacrificial component coupled to the end of the pipe, the method comprising:

separating a portion of the pipe from the sacrificial component at a greater distance than the coupling distance, thereby transferring the coupling of the plug with the pipe independently of the sacrificial component to a coupling with the sacrificial component independently of the pipe;
and
removing the plug coupled with the sacrificial component out of an inside of the pipe.

Dependencies are inferred from the claim text.
