API 570. An NDE examiner is not required to be an authorized piping inspector. Whenever the term inspector is used in API 570, it refers to an authorized piping inspector. auxiliary piping Instrument and machinery piping, typically small-bore secondary process piping that can be isolated from primary piping systems. Examples include flush lines, seal oil lines, analyzer lines, balance lines, buffer gas lines, drains, and vents. condition monitoring locations CMLs construction code The code or standard to which the piping system was originally built (. ASME B31.3). corrosion barrier The corrosion allowance in FRP equipment typically composed of an inner surface and an interior layer which is specified as necessary to provide the best overall resistance to chemical attack. corrosion rate The rate of metal loss due to erosion, erosion/corrosion or the chemical reaction(s) with the environment, either internal and/or external. corrosion specialist A person acceptable to the owner/user who is knowledgeable and experienced in the specific process chemistries, corrosion degradation mechanisms, materials selection, corrosion mitigation methods, corrosion monitoring techniques, and their impact on piping systems. critical check valves Check valves in piping systems that have been identified as vital to process safety. damage mechanism Any type of deterioration encountered in the refining and chemical process industry that can result in flaws/defects that can affect the integrity of piping (e.g. corrosion, cracking, erosion, dents, and other mechanical, physical or chemical impacts). See API 571 for a comprehensive list and description of damage mechanisms.
