This standard provides a general guide for the application of effective cathodic protection (CP) to all types of oil-treating vessels containing a free water phase (the electrolyte). It is intended to be used by facility owners, contractors, inspectors, vessels equipment specialists, CP system designers, manufacturers, and others concerned with corrosion mitigation by using cathodic protection systems. The procedures in this standard may best be applied under the direction of a corrosion engineer and by persons with experience and knowledge of the design, installation, operation, maintenance, and control of corrosion protection in the oil-treating vessels containing the electrolyte.
Coatings and materials are discussed in this document in conjunction with the cathodic protection design, as the coating is a major factor when designing a cathodic protection system.
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 standard is presented for the use of metallic corrosion coupons in hydrocarbon production and processing facilities, including but not limited to drilling, production, and transportation operations on land, onshore and offshore. Hydrocarbon operations handle fluids including but not limited to oil, water, gas, condensate, and drilling fluids.
This NACE Standard Practice aims to provide guidance for selection and application of Corrosion Inhibitors (CI) for upstream oil and gas processes conditions exposed to corrosive environments.
The application of effective Corrosion Inhibitors (CI) in Oil and Gas production is essential to enable long term use of carbon steel in corrosive production environments. These chemical CI products can be applied continuously, or on a Batch (BI) basis. The effectiveness of CIs(products) that are applied has to be assured for the range of conditions associated with the application and for the lifetime of the facility. The assurance is predominantly achieved through laboratory testing. However, field evaluation of CIs can be a significant part of the assurance process.
This Association for Materials Protection and Performance (AMPP) standard test method presents guidelines and procedures for use primarily by corrosion control personnel in the pipeline industry to determine the general condition of a pipeline coating. These techniques are used to measure the coating conductance (inverse of coating resistance) on sections of underground pipelines. This test method applies only to pipe coated with dielectric coatings.
When surveying a coated pipeline system, it may be necessary to determine the conductance of the coating. The conductance of a coating can vary considerably along the pipeline. Variations may be caused by changes in average soil resistivity, terrain, and quality of construction. To obtain data for coating conductance calculations, interrupted structure-to-electrolyte potentials and line current readings are taken at pre-selected intervals. It should be noted that the average soil resistivity has a direct effect on the coating conductance measurement. Because soil resistivity can affect the coating conductance, it must be known when evaluating a section of a pipeline coating.
HISTORICAL DOCUMENT.
This standard addresses the testing of metals for resistance to cracking failure under the combined action of tensile stress and corrosion in aqueous environments containing hydrogen sulfide (H2S). This phenomenon is generally termed sulfide stress cracking (SSC) when operating at room temperature and stress corrosion cracking (SCC) when operating at higher temperatures. In recognition of the variation with temperature and with different materials this phenomenon is herein called environmental cracking (EC). For the purposes of this standard, EC includes only SSC, SCC, and hydrogen stress cracking (HSC).
Testing of metals subjected to tensile stresses for resistance to cracking failure in low-pH aqueous environments containing hydrogen sulfide (H2S). Covers sulfide stress cracking and stress corrosion cracking.
HISTORICAL DOCUMENT. Nondestructive test method for the detection of holidays in polymeric coatings of 250 to 760 µm (10 to 30 mils) in metallic tubular goods used in the oil and gas industry. Apparatus, Procedure, Reporting.
This standard covers internal tubular polymeric coatings on a steel pipe/piping substrate. The standard defines and provides a procedure for the determination of the presence of holidays in a thick-film coating. This test method is based on the current technology and experience of the petroleum production industry This standard is intended for end users, manufacturers, applicators, corrosion engineers, and quality inspectors of internally coated metallic tubular goods.
This standard test method describes a quality assurance procedure for determining the potential and current capacity characteristics under laboratory conditions for aluminum and zinc alloy anodes used for cathodic protection (CP). Field performance of anodes should be evaluated to correspond to actual anode performance.
This standard is intended primarily for users, designers, and manufacturers involved with the application of CP in marine environments. This standard can be used by manufacturers and users of aluminum and zinc anodes for quality control verification. The most common usage is expected to be by manufacturers to meet quality control requirements requested by the purchasing user.
HISTORICAL DOCUMENT. This standard describes a test method to screen scale inhibitors for their ability to prevent precipitation of BaSO4 or SrSO4, or both, from oilfield brines. This standard test method is intended to provide the user with a relative and quantitative measure of the ability of scale inhibitors to prevent (1) the formation and (2) the precipitation of solid BaSO4 or SrSO4, or both, which are necessary and critical stages in scale deposition
