API RP 982 - Inspection and Assessment of Refractory Linings

Explore this topic

API RP 982, Inspection and Assessment of Refractory Linings, is a recommended practice developed and published by the American Petroleum Institute (API) that details industry practices, requirements, and guidance for the installation, in-service inspection, and repair assessment of refractory lining in equipment used in general refinery services. The purpose of this recommended practice is to enhance equipment reliability, bolster operating efficiency, increase personnel safety, and promote operational process safety across the natural gas and oil industry. The first edition of API RP 982 was published in October 2023.

While numerous existing API standards have covered refractory inspection methods and the qualifications of refractory inspectors, there has been little guidance on what constitutes a refractory inspection. API RP 982 fills in these critical gaps, providing guidelines on what equipment should be inspected, what elements to consider during an inspection, appropriate inspection tools, and the requisite competencies for inspectors.

API RP 982 encompasses an extensive array of refinery equipment, including fluid solid units, fluid catalytic cracker units, reforming units, fired heaters, incinerators, sulfur recovery units, flue gas ducts, calcines, steam-methane reformers, hydrogen plant and transfer lines, cracker furnaces, boilers, and flue gas stacks. The refractory linings in these units serve essential purposes, including:

  • Providing thermal protection for equipment;
  • Increasing energy retention and process efficiency;
  • Resisting processes that cause abrasion and corrosion; and
  • Enhancing personnel safety

API RP 982 includes applications for fired furnaces, which are used extensively in the industry to heat hydrocarbon feedstocks for various high-temperature processes. These furnaces manage the interaction and flow of liquids, solids, and gases at elevated temperatures. Performing a reliable assessment of this lining is crucial for maximizing the furnace’s productivity and durability.

Following API RP 982 can help organizations optimize furnace performance, reduce energy consumption, and minimize downtime. It can also foster better and more informed decision-making regarding the condition of the existing lining and the necessity of making repairs.

An API Individual Certification Program (ICP) certification for API RP 982 was released in 2024 to help identify individuals possessing knowledge of API RP 982 Inspection and Assessment of Refractory Linings. API RP 982 complements several other ICP certifications and API standards, including API 936, Refractory Installation Quality Control—Inspection and Testing Monolithic Refractory; API 975, Refractory Installation Quality Control—Inspection and Testing of Refractory Brick Systems and Materials; and API 976, Refractory Installation Quality Control—Inspection and Testing of AES/RCF Fiber Linings. Collectively, with the release of API RP 982, they strengthen the quality and reliability of refractory installations.
