Abstract

A graphite lubricant system for applying a coating of the lubricant to successive mandrels in a seamless pipe mill just prior to their insertion therein. The system provides for the selective application of the smokeless lubricant to the mandrels before they are inserted within the seamless pipe shell and both are run into the mill itself. In order to prevent the lubricant from clogging, the system includes a self-flushing arrangement which provides a cleaning function thereto when the system has been inactive for a given amount of time.
