This AMPP standard practice identifies procedures to determine the need for cathodic protection (CP) and the current requirements to achieve CP of well casings associated with land-based and offshore oil and gas production and gas storage. The standard is applicable to single or multi-phase production (oil, gas and water), reinjection (for product stor- age, product disposal, or reservoir maintenance) as well as for geothermal wells. It also outlines practices for the design and installation of CP systems and for their operation and maintenance. The purpose of this standard is to ensure more effective prevention of corrosion of well casings by making available reliable information about CP as it relates to well casings. This standard is intended for use by corrosion engineers in oil and gas production, especially those concerned with the CP of steel well casings.

Provides a procedure for electrical detection of minute discontinuities in coating systems that are liquid-applied to conductive substrates other than pipelines.
The purpose of this standard is to provide the means of detecting pinholes, flaws, or holidays in a coating system that may result in its premature failure, thereby possibly decreasing the life expectancy of the asset. This standard documents the equipment and the process of using electrical current to identify these holidays in a repeatable and realistic manner for both field and shop coating applications.
HISTORICAL DOCUMENT. This standard presents guidelines for the proper application of plastic coatings to the internal surfaces of oilfield tubular goods and accessories. This standard addresses initial inspection of the tubular goods and accessories prior to coating, surface preparation, coating application, coating inspection, coupling/connection make-up, quality control, handling, storage, shipping, and marking.

HISTORICAL DOCUMENT. Describes the use of iron counts as a corrosion monitoring method and some problems encountered. Includes sections on sampling, analysis, and interpretation.
This standard practice describes the use of iron counts as a corrosion-monitoring method and some common problems encountered when using this method. This standard is a guide for those designing corrosion-monitoring programs as well as those carrying out the programs in the field.
HISTORICAL DOCUMENT. Guidelines for fabrication, welding, and installation of clad plate bonded to air pollution control or other equipment such as FGD systems, ducts, and stacks.
The purpose of this standard practice is to provide technical and quality assurance guidelines for the fabrication, welding, and installation of stainless chromium-nickel steel and nickel-alloy roll-bonded and explosion-bonded clad plate in air pollution control equipment. It is intended for use by personnel including architect-engineers, designers, fabricators, and personnel from electric utilities.
HISTORICAL DOCUMENT. Acceptable practices for the design, fabrication, installation, and maintenance of steel-cased metallic pipelines. For use by personnel in the pipeline industry.
The use of cased carrier pipe for pipelines crossing under highways and railroads has been common practice in the industry. The first cased crossings were made using large-diameter pipe. The carrier pipe was mechanically coupled and pushed through the casing, and the coupling or collars were in direct contact with it. When coatings came into general use, isolating spacers were made of hemp rope saturated with pipe-coating enamel. End seals consisting of either concrete or pipe-coating enamel were poured into each end of the casing. The current practice of installing cased carrier pipe has changed only slightly since the beginning of its use. External loading of the carrier pipe has now been eliminated by the installation of heavy-wall casing pipe, and isolating spacers are used to prevent electrical contact between the casing and the carrier pipe. End seals are used to keep electrolyte (e.g., mud, water) out of the annular space between the carrier pipe and casing.
HISTORICAL DOCUMENT. Stress corrosion cracking direct assessment (SCCDA) is a structured process that is intended to assist pipeline companies in assessing the extent of stress corrosion cracking (SCC) on a section of buried pipeline and thus contribute to their efforts to improve safety by reducing the impact of external SCC on pipeline integrity. Primary guidance for assessing the structural integrity of a pipeline that has a significant risk of containing stress corrosion cracks is provided in Part A3 of ASME(1) B31.8S,1 which identifies several options for inspection and mitigation activities. The recommended practice for SCCDA presented in this standard addresses the situation in which a pipeline company has identified a portion of its pipeline as an area of interest with respect to SCC based on its history, operations, and risk assessment process and has decided that direct assessment is an appropriate approach for integrity assessment. This standard provides guidance for managing SCC by selecting potential pipeline segments, selecting dig sites within those segments, inspecting the pipe, collecting and analyzing data during the dig, establishing a mitigation program, defining the reevaluation interval, and evaluating the effectiveness of the SCCDA process.
