API 570 Certification Overview

The API 570 Piping Inspector certification is recognized across the refining, petrochemical, power generation, and chemical manufacturing industries. This credential demonstrates that an inspector possesses the knowledge and skills necessary to inspect in-service piping systems, assess their mechanical integrity, and determine fitness-for-service.

API 570 inspectors are responsible for evaluating piping systems for corrosion, erosion, and other degradation mechanisms. They establish inspection plans, interpret inspection results, and make recommendations for continued operation, repair, or replacement of piping components. This certification is essential for professionals working in refining and petrochemical facilities where piping reliability is critical to safe operations.

The certification standard covers standard and specialty piping, including carbon steel, stainless steel, and specialty alloy systems. It requires comprehensive knowledge of materials, corrosion mechanisms, inspection techniques, applicable codes and standards, and fitness-for-service assessment methodologies.
