This standard recommended practice is a general guide for the application of effective cathodic protection to all oil-treating vessels. This standard covers design criteria, the selection and installation of applicable systems, and the operation, monitoring, and maintenance of installed systems. There are many design variations in existing oil-treating vessels, with new designs being introduced continually. The preparation of a recommended practice for the cathodic protection of each individual vessel design is not practical. Therefore, this standard is not specific with respect to one or more vessel designs. 11 is intended for use by corrosion engineers involved in oil and gas production, especially those concerned with surface facilities. Nothing contained in this standard is intended to conflict with applicable codes, including OSHA< 1l regulations.

This standard was originally prepared in 1975 by Task Group T-1 E-6, a component of Unit Committee T-1 E on Cathodic Protection of Oilfield Equipment. The task group was composed of corrosion consultants, corrosion engineers from oil- and gas-producing companies, representatives from manufacturers, and others concerned with internal corrosion control in oil-treating vessels.

This standard was revised in 1995 by Task Group T-1 E-11 and is issued under the auspices of Group Committee T-1 on Corrosion Control in Petroleum Production.

This standard presents recommended practices for the cathodic protection of internal surfaces of oil-treating vessels, heat exchangers, or the water side of process vessels.
