NACE SP0394 Application, Performance, and Quality Control of Plant-Applied Single Layer Fusion-Bonded Epoxy External Pipe Coating
This NACE standard describes methods for qualifying and controlling the quality of plant-applied, single-layer fusion-bonded epoxy (FBE) coatings to the external surfaces of carbon steel pipe, provides guidelines for proper application, and identifies inspection and repair techniques to obtain the best applied FBE coating system. It is intended for use by corrosion control personnel concerned with mitigation of corrosion on buried and submerged piping used for transportation and storage of oil, gas, water, and similar products.

Provides the most current technology and industry practices for the use of field-applied fusion-bonded epoxy (FBE) external pipe coating systems for girth weld joints. This standard is intended for use by corrosion control personnel, design engineers, project managers, purchasing personnel, and construction engineers and managers. It is applicable to underground steel pipelines in the oil and gas gathering, distribution, and transmission industries. Key words: coatings, field joints, fusion-bonded epoxy, pipelines, protective coatings.
NACE SP0100 Cathodic Protection to Control External Corrosion of Concrete Pressure Pipelines and Mortar-Coated Steel Pipelines for Water or Wastewater Service
Furnishes guidelines that provide corrosion control personnel, owners, operators, designers, manufacturers, and contractors information on corrosion control of prestressed concrete cylinder pipe (PCCP) and mortar-coated steel pipelines for water or wastewater service through the application of cathodic protection. The guidelines presented are applicable to new or existing buried pipelines with or without a supplemental coating.
ASTM G8 – Standard Test Methods for Cathodic Disbonding of Pipeline Coatings
Significance and Use
Breaks or holidays in pipe coatings may expose the pipe to possible corrosion, since after a pipe has been installed underground, the surrounding earth will be more or less moisture-bearing and it constitutes an effective electrolyte. Damage to pipe coating is almost unavoidable during transportation and construction. Normal soil potentials as well as applied cathodic protection potentials may cause loosening of the coating, beginning at holiday edges, in some cases increasing the apparent size of the holiday. Holidays may also be caused by such potentials. While apparently loosened coating and cathodic holidays may not result in corrosion, this test provides accelerated conditions for loosening to occur and therefore gives a measure of resistance of coatings to this type of action.
AWWA C210 Liquid-Epoxy Coatings and Linings for Steel Water Pipe and Fittings
This standard describes the material and application for shop- and field-applied, liquid-epoxy coatings and linings used in the water-supply industry for steel water pipelines installed underground or underwater, under normal construction conditions.
The coating and lining systems may consist of any of the following three types:
1 A two-part chemically cured epoxy primer and one or more coats of a different two-part chemically cured epoxy top-coat;
2 Two or more coats of the same two-part chemically cured epoxy, in which case the first coat shall be considered the prine coat; or
3 A single coat of a two-part chemically cured epoxy.
This edition of the standard includes numerous updates and additions, including a new name, and various sections were renamed, rearranged, and revised.
AWWA C213 Fusion-Bonded Epoxy Coatings and Linings for Steel Water Pipe and Fittings
This standard describes the material, application, and testing requirements for fusion-bonded epoxy coatings and linings for steel water pipe, special sections, welded joints, connections, and fittings for steel water pipelines installed underground or underwater. Fusion-bonded epoxy coatings are heat-activated, chemically cured systems. This standard provides the minimum requirements for product.

Paints and Coatings
For all paints and coatings, the manufacturer shall submit detailed use instructions for the laboratory preparation and application that are representative of their published use instructions for factory or field applications. Use instructions shall specify the appropriate preparation and application procedures, including order of application for multiple layer systems, substrate preparation (including use of specific primer), subcomponent mixing ratio, induction time, thinning, application method, application thickness(es), curing schedule, and final cure time prior to water immersion. Coating systems that are composed of multiple products (e.g., primer, intermediate coats), and top coat, including any thinners) shall be evaluated as an applied system. Use instructions indicating the coating/paint will rehabilitate existing pipe and that the water system can be returned to service within 48 hours following the final cure shall be evaluated as immediate return to service paint/coating systems.
Public listing for a coating/paint shall include application procedures including order of application for multiple layer systems, use of a specific primer if one is used, subcomponent mixing ratio, thinning, application method, application thickness(es), curing schedule and final cure time and temperature prior to water immersion. Paint/coating system intended to be applied to pipe shall be designated as “certified for use on new pipe” or “certified for use on pipe intended for immediate return to service”.

ASME A13.1 Scheme for the Identification of Piping Systems
A13.1 is intended to establish a common system to assist in identification of hazardous materials conveyed in piping systems and their hazards when released in the environment. This scheme concerns identification of contents of piping systems in industrial and power plants. It is also recommended for the identification of piping systems used in commercial and institutional installations, and in buildings used for public assembly. It does not apply to pipes buried in the ground nor to electrical conduits.
3.2 Color: “Color should be used to identify the characteristic hazards of the contents. Color should be displayed on, or contiguous to, the piping by any physical means, but its use shall be in combination with the legend…”
“The applicable GHS pictograms as illustrated in Fig. 1 may be included as part of the legend. Where piping is connected to containers that are labeled in accordance with GHS requirements, a corresponding label on the piping may be provided. The corresponding label should contain at least the product name or identifier, the pictogram, the signal word, and the physical, health and environmental hazard statements.”
CorrCompilations: FBE External Coatings for Pipelines (E-Book), https://store.nace.org/corrcompilations-fbe-external-coatings-for-pipelines-e-book-
This compilation is intended for designers, corrosion and pipeline engineers with a working knowledge of fusion-bonded epoxy (FBE) pipeline coatings, and coating engineers seeking an in-depth understanding of current FBE practices. These papers present issues of current interest in the field or are a useful resource for those seeking a solid foundation in the topic.
The expectation is that the reader will leave with a better understanding of failure modes, the mechanisms of protection and limitations of the technology, and will have more confidence when specifying FBE for field applications.
The emphasis is exclusively on external FBE coatings on buried or submerged pipelines. Inevitably, there is some overlap with pipeline-related fields such as cathodic protection, corrosion, integrity management, inspection, and qualification testing for coating products. Also in this compilation is a comprehensive listing of coating standards and specifications which the reader may find a helpful resource. Almost all of the papers selected were published within the last decade and address contemporary issues pertinent to pipeline coatings.
