Abstract
A protector for protecting the internal bore of a pipeline bend from a line being pulled through the pipeline bend during servicing operations including a first liner section which will travel along the pipeline to the pipeline bend but which will not pass through the pipeline bend, a one or more of second liner sections which will pass through the bend but are connected to the first liner section, releasably connecting the liner sections to a service pig, pulling the liner sections into the pipeline with the service pig until the first liner section encounters the bend and stops, continuing travel with the service pig and releasing the service pig from the liner sections, and constraining a line connected to the service pig to be positioned within the liner sections rather than contacting the pipeline bend.
