API RP 572 - Inspection of Pressure Vessels

Last update: Jan 16, 2017

API RP 572, Inspection of Pressure Vessels, is a recommended practice developed and published by the American Petroleum Institute (API) that covers the inspection of pressure vessels, including those with a design pressure under 15 psig, and the standards for their construction and maintenance. In addition, RP 572 also discusses, with relation to pressure vessels, the reasons for inspection, causes of deterioration, the frequency and methods of inspection, methods of repair, and preparation of records and reports.

This recommended practice covers a large variety of different topics related to the inspection of pressure vessels including safety precautions, thickness measurements, both internal and external inspections, and special methods of detecting mechanical damage. The first edition of the recommended practice was originally published in January of 1992, with the most recent 4th Edition published in December of 2016.

To be most effective, this recommended practice requires knowledge of other API standards and practices. Some of these standards include, but are not limited to:

It is also helpful to have a general familiarity with the ASME Boiler and Pressure Vessel Code, Section VIII: Pressure Vessels when using API RP 572.
