b) Classes of piping systems that are excluded are as follows. 1) Piping systems on movable structures covered by jurisdictional regulations, including piping systems on trucks, ships, barges, and other mobile equipment. 2) Piping systems that are an integral part or component of rotating or reciprocating mechanical devices, such as pumps, compressors, turbines, generators, engines, and hydraulic or pneumatic cylinders where the primary design considerations and/or stresses are derived from the functional requirements of the device. 3) Internal piping or tubing of fired heaters and boilers, including tubes, tube headers, return bends, external crossovers, and manifolds. 4) Pressure vessels, heaters, furnaces, heat exchangers, and other fluid handling or processing equipment, including internal piping and connections for external piping. 5) Plumbing, sanitary sewers, process waste sewers, and storm sewers. 6) Piping or tubing with an outside diameter not exceeding that of NPS 1 / 2 . 7) Nonmetallic piping and polymeric or glass-lined piping. 8) Cryogenic piping systems (e.g. liquefied natural gas [LNG]). 9) Piping regulated under USDOT 49 CFR 195. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. API Publication 340, Liquid Release Prevention and Detection Measures for Aboveground Storage Facilities API 570, Piping Inspection Code: Inspection, Repair, Alteration, and Rerating of In-service Piping Systems API Recommended Practice 571, Damage Mechanisms Affecting Fixed Equipment in the Refining Industry API Recommended Practice 574, Inspection of Piping System Components API Recommended Practice 577, Welding Inspection and Metallurgy API Standard 579-1, Fitness-For-Service
3 Terms, Acronyms, and Definitions 3.1 Definitions For the purposes of this document, the following definitions apply. 3.1.1 alteration Physical change, approved by a piping engineer, having design implications in any component that may affect the pressure containing capability or flexibility of a piping system beyond the scope of its original design. NOTE The following are not considered alterations: comparable or duplicate replacements and the addition of small-bore attachments that do not require reinforcement or additional support. 3.1.2 applicable code Requirement(s), requirement section(s), or other recognized and generally accepted engineering Standard or practice to which the piping system was built or which is deemed by the Owner/User or the piping engineer to be most appropriate for the situation. 3.1.3 authorized inspection agency Defined as any of the following. a) An organization representing an insurance company that is licensed or registered to write insurance for piping systems. b) An Owner/User of piping systems that has designated a certified company or person to function as the authorized inspector. c) An independent organization employed by or under contract to the Owner/User of piping systems that are used only by the Owner. d) An independent organization licensed or recognized by the jurisdiction in which the piping system is used and employed by or under contract to the Owner/User. 3.1.4 authorized piping inspector Employee of an authorized inspection agency who is qualified by experience, training and accredited testing to perform the functions specified in this document. NOTE Whenever the term inspector is used in this document, it refers to an authorized piping inspector. A nondestructive (NDE) examiner is not required to be an authorized piping inspector.
3.1.5 corrosion under insulation Generalized corrosion that developed on the outer surface of unprotected piping beneath fully encompassing insulation when moisture is apparent. 3.1.6 deadlegs Internal areas of a piping system that are isolated by valves or location having no flow for more than three consecutive months. 3.1.7 defect Flaw or other discontinuity noted during inspection of a type or magnitude exceeding the acceptable criteria. 3.1.8 distribution terminal See definition for “terminal”. 3.1.9 environmental cracking The intergranular or transgranular cracking of a material due to the combined action of tensile stress and a specific environment. 3.1.10 examiner Person trained and qualified to provide quality functions of a component manufacturer, fabricator or erector. 3.1.11 guided wave ultrasonic testing Nondestructive examination technique that utilizes ultrasonic waves that travel down the length of pipe, screening areas that are otherwise difficult to access.
