API RP 578-2018 pdf download.Guidelines for a Material Verification Program (MVP) for New and Existing Assets.
1 1.1 Scope Purpose The purpose of this recommended practice (RP) is to provide guidelines for an owner/user to develop and implement a material verification program (MVP) as part of an asset integrity program. The MVP uses positive material identification and other methods to verify that the nominal composition of an asset, an asset component, or weldment within the pressure envelope is consistent with the selected or specified construction materials. A well-designed and well-implemented MVP is an important management system used to minimize the potential for release of hazardous substances due to nonconforming materials of construction. 1.2 About this Document This recommended practice provides the guidelines for material verification programs involving ferrous and nonferrous alloys during the construction, installation, maintenance, and inspection of new and existing process equipment. It applies to metallic materials purchased for use either directly by the owner/user or indirectly through distributors, fabricators, or contractors, and includes the supply, fabrication, and installation of these materials. This recommended practice is applicable to all refining and petrochemical industries, and may be applied in other industries and or businesses at the discretion of the owner/user. It is intended to be applied by any owner/user wishing to verify and/or validate that the materials of construction received, fabricated, and/or installed are in accordance with material and/or company specification(s). 1.3 Supersedes Notice This version of API RP 578 (third edition) supersedes and wholly replaces the second edition (201 0) of API RP 578 (Material Verification Program for New and Existing Alloy Piping Systems). The third edition contains many of the same paragraphs and language of the second edition, but it has been revised, reformatted, and re-visualized into a more encompassing document for all types of assets that may have an applicable material verification program.
3.1.2 asset Property or equipment owned by a company that is either directly or indirectly involved with the manufacturing process. 3.1.3 distributor A warehousing supplier for manufacturers or suppliers of materials or components. 3.1.4 extent of examination The specified percentage of the number of items to be examined in an inspection lot. 3.1.5 fabricator An organization that utilizes the materials of construction affected by this recommended practice in order to create an asset. 3.1.6 heat A batch of metal made at the same time, able to be traced from its original constituents and manufacturing process. 3.1.7 inspection lot A group of items or materials of the same type from a common source from which a sample is to be drawn for examination. NOTE An inspection lot does not include items from more than one heat. 3.1.8 lot size The number of items available in the inspection lot at the time a representative sample is selected. 3.1.9 material certifications (certificates of compliance) See “mill test report.” 3.1.10 material manufacturer An organization that performs or supervises and directly controls one or more of the operations that affect the chemical composition or mechanical properties of a metallic material. 3.1.11 material nonconformance A positive material identification (PMI) result that does not conform with material specified. 3.1.12 material supplier An organization that supplies material furnished and certified by a material manufacturer, but does not perform any operation intended to alter the material properties required by the applicable material specification. 3.1.13 mill test report (MTR) A quality assurance document used in the steelmaking industry that certifies a material’s compliance with appropriate standards, including physical and chemical specifications, and applicable dimensions. The MTR also includes a date of production and testing, and may include notation about method of fabrication.
