API 571 Corrosion and Materials Course Scope
This recommended practice discusses damage mechanisms applicable to oil refineries; however, much of the information herein can also be applied to petrochemical and other industrial applications, as the user deems appropriate. API 571 Corrosion and Materials Course covers, it is up to the user to determine the applicability and appropriateness of the information contained herein as it applies to their facility.
API 571 is a reference document that provides useful information by itself and also complements other
API standards and recommended practices. The document should be utilized as a reference to other integrity related documents. It is intended to contribute to the overall management of pressure equipment integrity and is a useful resource for many mechanical integrity program activities including:
a) identification of existing damage or deterioration and anticipated rates of degradation,
b) identification of future damage mechanism susceptibilities,
c) development and maintenance of inspection and monitoring strategies, programs, and plans (e.g. per
API 510, API 570, and API 653),
d) implementation and monitoring of integrity operating windows (IOWs) (see API 584),
e) development of corrosion control documents (CCDs) (see API 970),
f) implementation of Risk-Based Inspection (RBI) programs (see API 580 and API 581),
g) conducting Fitness-For-Service (FFS) assessments (see API 579-1/ASME FFS-1),
h) application of proper examination techniques, and
i) conducting pressure equipment integrity incident investigations (see API 585).
The information for each damage mechanism is provided in a set format as shown below.
— Name of the Mechanism—The term commonly used to describe or name the mechanism.
— Description of Damage—A basic description of the damage mechanism.
— Affected Materials—A list of the materials prone to the damage mechanism.
— Critical Factors—A list of factors that affect the damage mechanism (i.e. rate of damage).
— Affected Units or Equipment—A list of the affected equipment and/or units where the damage mechanism commonly occurs. This information is also shown on generic process flow diagrams (PFDs) for typical process units.
— Appearance or Morphology of Damage—A description of the damage mechanism, with pictures in some cases, to assist with recognition of the damage.
— Prevention/Mitigation—API 571 Corrosion and Materials Course Methods to prevent or mitigate the damage and in some cases to evaluate by engineering analysis.
— Inspection and Monitoring—Guidance for nondestructive examination (NDE) and other methods for
detecting, monitoring, characterizing, sizing, and determining the severity or extent of damage or
deterioration.
— Related Mechanisms—A list of related damage mechanisms.
— References—A list of references cited, relied upon, or that provide background and other pertinent
information.
API 571 Corrosion and Materials Course Generic PFDs are provided in Section 4 to assist the user in determining primary locations where some of the significant damage mechanisms are commonly found.
Terms and Definitions
For the purposes of this document, the following definitions apply.
austenitic
API 571 Corrosion and Materials Course covers A term that refers to a type of metallurgical structure (austenite) normally found in 300 series stainless steel (SS) and nickel-based alloys. These materials have a face centered cubic crystallographic structure and are generally nonmagnetic.
austenitic stainless steels
The 300 series SS, which commonly include Types 304, 304L, 304H, 309, 310, 316, 316L, 316H, 317, 317L,
321, 321H, 347, and 347H. The “L” and “H” suffixes refer to controlled ranges of low and high carbon content, respectively. These alloys are characterized by an austenitic structure.
carbon steel
An alloy consisting primarily of iron (Fe) with a small amount of carbon (C). Carbon steels do not have alloying elements intentionally added. API 571 Corrosion and Materials Course However, there may be small amounts of elements permitted by specifications such as ASTM A516 and ASTM A106, for example, that can affect corrosion-related properties, hardness after welding, and toughness. Elements that may be found in small quantities include Mn, Cr, Ni, Mo, Cu, S, Si, P, Al, V, and B.
