Which API publication is specifically focused on the inspection of pressure vessels?

API Recommended Practice 572 specifically addresses the inspection of pressure vessels. This publication provides guidelines and standards for conducting inspections throughout the lifecycle of pressure vessels. It includes recommendations on determining the condition of the vessels, identifying potential degradation mechanisms, and ensuring compliance with both industry and regulatory standards.

The importance of RP 572 lies in its thorough coverage of various aspects involved in pressure vessel inspection, including maintenance practices, inspection schedules, and documentation requirements, all aimed at safeguarding against failures and ensuring operational integrity. This makes it a key resource for inspectors who are tasked with evaluating the safety and performance of pressurized equipment.

In comparison, the other API Recommended Practices relate to different aspects or types of equipment and do not specifically focus on the inspection procedures necessary for pressure vessels.
