API-571 Corrosion and Materials Professional Exam | Free Practice Demos (2026)

Описание: API-571 Corrosion and Materials Professional Exam | Free Practice Demos (2026)

The API-571 Corrosion and Materials Professional certification is one of the most respected credentials for corrosion engineers, inspectors, and materials professionals in the refining and petrochemical industry. It validates your understanding of damage mechanisms, corrosion processes, and material degradation affecting fixed equipment—critical knowledge for inspection, integrity management, and risk-based decision-making.

What Does the API-571 Exam Test?

The API-571 exam is based entirely on API RP 571 (Damage Mechanisms Affecting Fixed Equipment in the Refining Industry, 3rd Edition) and focuses on real-world corrosion scenarios, not just theory. It will test your knowledge, including:
1. Terms, Definitions, and Acronyms
2. Damage Mechanisms
Name of the Mechanism
Description of Damage
Affected Materials
Critical Factors
Affected Units or Equipment
Appearance or Morphology of Damage
Prevention/Mitigation
Inspection and Monitoring

1. Which of the following is the primary cause of internal damage in carbon steel during High Temperature Hydrogen Attack?
A. The formation of methane gas bubbles at grain boundaries.
B. The migration of chromium to the surface of the metal.
C. The absorption of atomic oxygen into the crystal lattice.
D. The rapid increase in hardness due to martensite formation.
Answer: A
Mechanism of hydrogen-related internal damage in carbon steel at elevated temperatures. High Temperature Hydrogen Attack is a damage mechanism that occurs when carbon steel is exposed to high-temperature hydrogen environments. Hydrogen atoms diffuse into the steel and react with carbon to form methane. Because methane cannot diffuse out of the metal lattice, it accumulates at grain boundaries, causing internal pressure, microfissuring, decarburization, and loss of mechanical strength. HTHA is typically irreversible and can lead to sudden failure.

2. Which statement best describes the nature of Creep damage in refinery equipment?
A. It is a time-dependent deformation occurring under stress at high temperatures.
B. It occurs rapidly during sudden cooling of the metal.
C. It only affects equipment exposed to high pressure hydrogen.
D. It can be completely reversed by performing a full anneal.
Answer: A
Time-dependent deformation of metals at high temperature. Creep is a damage mechanism characterized by slow, progressive deformation of metal under sustained stress at elevated temperatures. It is a function of time, temperature, and applied stress. Over long periods, creep can lead to void formation, grain boundary cracking, and eventual rupture. Creep damage accumulates gradually and is not fully reversible.
