This paper will demonstrate a different and proven approach to internal corrosion control in steel tubing, line pipe and casing. Polyvinyl chloride (PVC) plastic and fiberglass-epoxy (FRP) insert linings can be installed in either new or used tubulars to prevent corrosion. These rigid linings afford a smooth uniform nominal inside diameter and are not affected by the rough pitted inner surfaces usually encountered in used pipe. Protecting the connections is a large part of the battle in corrosion control. For this purpose, the lining system uses the more practical reinforced oil-resistant rubber corrosion barrier ring. This rubber corrosion barrier ring is compressed when the connection is made up in the field. The design of this system will be explained in detail as we discuss the installation, handling and running procedures that make this system corrosion resistant.
