API RP 573 - Inspection of Fired Boilers and Heaters

Last update: Jan 16, 2017

API RP 573, Inspection of Fired Boilers and Heaters, is a recommended practice published and developed by the American Petroleum Institute (API) that covers the inspection practices for fired boilers and process heaters (furnaces) used in petroleum refineries and petrochemical plants. This document, and the recommendations within, are intended to improve equipment reliability and plant safety. It describes the operating variables which impact reliability to guarantee that the appropriate data is obtained via inspection, both on- and off-stream, to guarantee the current and future performance of the equipment. The first edition of the practice was originally published in February of 2003 and the most recent release was the third edition, which was published in October of 2013.

This recommended practice covers a variety of different topics related to boilers and heaters, including a list of common boiler and heater designs and types, mechanical reliability and reliability programs, and various topics related to inspection, such as the purpose of inspection and inspector qualifications. It also provides a list of damage mechanisms commonly affecting boiler and heater tubes along with other components.
