Four-point bend testing is used extensively in the oil and gas industry to evaluate resistance of metals to sulfide stress cracking and stress corrosion cracking. The face of the specimen to be tested is stressed in tension and the reverse face in compression. The test is carried out for a specified exposure period with the specimen held under constant displacement using compact loading jigs. The compact nature of the jigs enables testing of several specimens in the test vessel simultaneously. Despite the apparent simplicity of the test, there are many factors that can influence the test results. The purpose of this standard is to establish a reliable methodology for conducting the tests to enhance repeatability and reproducibility of test data. The results of the tests can then be used with greater confidence to rank the performance of metals, the relative aggressiveness of environments, and to provide a basis for qualifying metals for service application. As such, the standard will be of particular benefit to materials and corrosion engineers in the oil and gas sector and to test laboratories providing critical data.

This technical report describes the associated corrosion mechanisms in refinery crude distillation unit (CDU) distillation tower overhead systems and current industry practices for mitigating or controlling this corrosion. Distillation towers in a typical CDU include a pre-flash tower, an atmospheric tower, and a vacuum tower. Feedstock, unit configurations, and associated process variables are addressed, from the crude oil storage tanks to the distillation tower overhead drums.
This standard practice provides the material characteristics, minimum system performance requirements, application methods, handling, shipping, and installation procedures for tape coatings for the prevention of external corrosion of underground or submerged pipelines. This standard is applicable to both carbon steel (CS) pipe and ductile iron (DI) pipe when the application of a tape coating system is desirable. This standard is intended for use by coating applicators, engineers, and pipeline owners as a guide to specifying application parameters.
The tape coatings covered in this standard are used as the external corrosion protection for new and existing pipes, girth welds, and fittings, and for repair and rehabilitation. The primary function of these tape coating systems is to pre- vent corrosion of the pipeline when used with or without cathodic protection (CP).
This nondestructive test method describes a procedure to detect discontinuities (“holidays”) in thin-film polymeric coatings of less than 330 µm (13 mils) dry film thickness (DFT) applied to the internal surfaces of metallic tubular goods used in the oil and gas industry. The apparatus and the recommended procedure for performing the test are described, as are methods of reporting the test data.
A separate test method, NACE TM0186, addresses holiday detection of internal tubular good coatings of 330 to 760 µm (13 to 30 mils) dry-film thickness.
This NACE/SSPC joint standard defines the Light Cleaning (WJ-4) degree of surface cleanliness of coated or uncoated metallic substrates achieved by the use of waterjet cleaning prior to the application of a protective coating or lining. Waterjet cleaning is the use of pressurized surface preparation water for removing coatings and other materials, including hazardous materials, from a substrate to achieve a defined degree of surface cleanliness. Waterjet cleaning includes various methods such as low-pressure water cleaning (LP WC), high-pressure water cleaning (HP WC), high-pressure waterjetting (HP WJ), and ultrahigh-pressure waterjetting (UHP WJ).
Asset owners, engineers, consultants, coating contractors, inspectors, and others are specifying allowable levels of surface soluble salts to prevent premature coating failures. The purpose of this standard is to provide guidance about the number of and locations for soluble salt tests on steel surfaces.
This standard establishes siting and frequency requirements for soluble salt testing before the application of a subsequent coating system to previously coated substrates and replacement substrate material. It does not include allowable limits of soluble salts, which are typically addressed by the procurement documents or the coating manufacturer’s documentation.
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 AMPP standard practice 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.
This NACE/SSPC joint standard defines the Very Thorough Cleaning (WJ-2) degree of surface cleanliness of coated or uncoated metallic substrates achieved by the use of waterjet cleaning prior to the application of a protective coating or lining. Waterjet cleaning is the use of pressurized surface preparation water for removing coatings and other materials, including hazardous materials, from a substrate to achieve a defined degree of surface cleanliness. Waterjet clean- ing includes various methods such as low-pressure water cleaning (LP WC), high-pressure water cleaning (HP WC), high-pressure waterjetting (HP WJ), and ultrahigh-pressure waterjetting (UHP WJ).
This standard practice provides technical and quality assurance guidelines for handling and installing nickel alloy, stainless steel, and titanium linings in air pollution control equipment (e.g., FGD systems, ducts, and stacks). The concepts and guidance included in this standard may also be useful in other process industries, but may require modification to meet the requirements of a particular process. This standard is intended to be a basis for preparation of a specification to be agreed on by contracting parties for the installation of wallpaper lining in air pollution control and other process equipment. It is the responsibility of users of this standard to determine the suitability of specific procedures, metals, and alloys for particular applications.
Note: This document was originally published with an error in Section H4.4, Equation (H2), page 33, Section H4.3.3 has a note added, page 33, and Figure H2, Figure H3, Figure H4, and Figure H5, pages 35-38 were enlarged to improve accuracy. These identified errors are corrected. The Errata sheet is included.
This standard practice presents guidelines for establishing requirements to ensure proper application and performance of plant-applied single-layer fusion-bonded epoxy (FBE) coatings to the external surfaces of carbon steel pipe.
The purpose of this AMPP test method is to standardize the testing methods and conditions used to determine the substrate and surface temperature limits for different thicknesses of insulative coatings used for personnel protection to be in compliance with ASTM C1055. The temperature limits determined when using this test method are specific for each coating tested at a particular thickness and substrate temperature. A standardized test method can validate the temperature limits of a coating used for personnel protection and enable direct comparison of its performance to other commercially available coatings. This test method is intended for use by facility owners, engineers, health and safety specialists, coatings manufacturers, and other interested parties.
