The purpose of this NACE International technical report is to provide basic information regarding the mechanisms involved with cathodic protection (CP) shielding for external coatings applied to carbon steel pipelines, and the manner in which the breakdown of coating systems may or may not contribute to CP shielding. It is intended to be a basic reference from which the tendency of a coating system to fail and shield CP may be understood on a conceptual basis. Non-corrosion-related pipeline protection systems, including concrete weight coating, polyethylene encasement, insulation, and mechanical pipeline protection systems, are outside the scope of this report. End users of this report may include pipeline designers, corrosion engineers, integrity management specialists, regulators, CP service providers, coating suppliers, coating service providers, equipment suppliers, and pipeline/facility owners.

This AMPP standard practice presents guidelines for galvanic cathodic protection (GCP) of reinforcing steel in atmospherically exposed concrete elements or structures. These guidelines are intended for owners, engineers, architects, contractors, and those concerned with the mitigation of reinforced concrete corrosion through the application of GCP systems. The information in this standard as it relates to GCP systems is intended for atmospherically exposed concrete structures and is not applicable to concrete with nonferrous reinforcement or epoxy-coated, galvanized, or other types of coated reinforcement. GCP applications for buried and submerged reinforced concrete structures are not addressed in this standard.
This standard covers surface preparation, material requirements, application, and handling of hot- and cold-applied wax and component wrappers and wax-based tape coating systems for the protection of underground pipelines, and valves. This standard is intended for use by corrosion control personnel, design engineers, project managers, purchasers, application contractors, and construction engineers and managers. The use of this standard in coordination with the manufacturer of the referenced materials herein will reduce the chance of their misapplication and will maximize their potential to provide long-term corrosion protection. This standard is also referenced by NACE SP0169, “Control of External Corrosion on Underground or Submerged Metallic Piping Systems.”
This standard presents methods and practices for achieving effective control of external corrosion on underground or submerged metallic piping systems and is intended for use by corrosion control personnel concerned with piping used for the transport of oil, gas, water, and other fluids. It is applicable to underground structures and piping buried on land, or submerged in water bodies such as lakes, rivers, bayous, and creeks.
Procedures to (1) assess corrosion (2) determine risk of corrosion and degradation (3) make decisions whether coating repair is needed (4) apply repair coatings.
Wax coating systems are designed to provide underground pipes with protection against corrosive environments. This standard recommended practice covers surface preparation, material requirements, application, and handling of hot- and cold-applied wax and component wrappers and wax-tape coating systems for the protection of underground pipe, fittings, and valves. This standard is intended for use by corrosion control personnel, design engineers, project managers, purchasers, and construction engineers and managers.

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.
