Overview of API 570 - Piping Inspection Code
API 570, Piping Inspection Code: In-Service Inspection, Repair, and Alteration of Piping Systems, is an inspection code developed and published by the American Petroleum Institute (API). The inspection code covers in-service inspection, rating repair, and alteration of metallic and fiberglass-reinforced plastic (FRP) piping systems and their respective pressure relieving devices. The most recent edition (4th Ed.) was released February 2016.

First published in 1993, API 570 establishes the requirements and guidelines needed to maintain the safety and mechanical integrity of piping systems after they have been commissioned. While it was primarily intended for those systems in the petroleum and chemical processing industries, this code can be applied to any industry that uses piping systems.

API 570 does not cover inspection, repair, or alteration procedures for specialty equipment or equipment that has been decommissioned. However, piping systems that are temporarily out of service and may be recommissioned in the future are covered by API 570.

API RP 574 supplements API 570 to provide information and best practices that assist practitioners in the “how to” inspect piping and common piping components.

Who is API 570 Pipe Inspector ?
Certified API 570 Piping inspectors must have a broad knowledge base relating to maintenance, inspection, alteration and repair of in-service metallic piping systems. The API 570 examination is designed to determine if applicants have such knowledge.

This certification program benefits employers and the industry as a whole by helping to:

• Provide a continued high level of safety through the use of inspectors specialized in process piping
• Improve management control of process unit inspection, repair, alteration and rerating
• Reduce the potential for inspection delays resulting from regulatory requirements

API 570 certification is valid for a three-year term and is accredited by the American National Standards Institute (ANSI). This accreditation ensures that the exam has been developed to the highest standard for openness and integrity and meets the rigorous requirements established under the International Organization for Standardization (ISO) 17024.

Industry Application
API 570 applies to piping systems that involve process fluids, hydrocarbons, chemical products, natural gas, high-pressure gasses, and other flammable or toxic fluids. Some piping systems such as fluid services operating below a certain threshold or fluid services involving water are optional in regards to API 570 requirements. Furthermore, fitness-for-service assessments and risk-based inspection are accepted methods under API 570 for evaluating on-stream piping systems and pressure containing components.
