Ensuring the safety and reliability of industrial facilities requires inspecting in-service piping. Industry standards like API 570 mandate this inspection. By following these guidelines, operators can identify potential issues early on, take corrective measures to prevent failures, and ensure the continued safe and reliable operation of their piping systems. In this article, we will cover the definition, the scope, and the latest update of API 570. We also add guidelines on how you can gain API 570 certification.

What Is API 570?

API 570 is a standard covering inspection, rating, repair, and alteration procedures for in-service metallic and fiberglass-reinforced plastic (FRP) piping systems and other pressure relief devices. The inspection code is for all hydrocarbon and chemical process piping in 1.2.1, placed in service, unless optional as per 1.2.2.

With the latest edition released in 2016, API 570 has been revised four times since it was published in 1993. At first, petroleum and chemical industries intended to use API 570, but it became widely used by any industry that utilizes piping systems.

What Is The Scope of API 570?

The API 570 standard addresses piping systems currently in service or those that might be recommissioned. However, retired or decommissioned process piping systems are not encompassed by this standard.

In the API 570 second edition (1998), the standard pertains to piping systems used for managing process fluids, hydrocarbons, and other hazardous fluids that could be flammable or toxic. Examples of such services include:

  1. Raw, intermediate, and finished petroleum products
  2. Raw, intermediate, and finished chemical products
  3. Catalyst lines
  4. Hydrogen, natural gas, fuel gas, and flare systems
  5. Sour water and hazardous waste streams above threshold limits, as defined by jurisdictional regulations
  6. Hazardous chemicals above threshold limits, as defined by jurisdictional regulations

What Is API 570 Latest Edition Update?

API 570 latest update was released in 2016, making it the fourth edition. The latest edition introduces several changes aimed at improving the inspection and maintenance of in-service piping systems. Further, there are hundreds of changes and edits made on its fourth edition, but some of the changes are mentioned as follows.

  1. The scope and definitions section of API 570 has been revised to provide more clarity regarding the types of piping systems covered under the standard.
  2. API 570 now includes new requirements for documenting the inspection and testing of piping systems, with specific criteria provided for the recording and retention of inspection and testing results.
  3. API 570 has changed with some information being relocated to RP 574, which is extensively cited in API 570. This means that the use of RP 574 has become crucial for the application of API 570.
  4. The standard now includes updated guidelines for the repair and alteration of piping systems, with new criteria used to evaluate the suitability of repaired or altered components.
  5. API 570 latest edition places greater emphasis on the use of non-destructive examination (NDE) techniques for monitoring Corrosion Under Insulation (CUI) and references the new RP 583, which provides guidelines for managing CUI in process equipment.
  6. The requirements for pressure testing of piping systems have been revised, with new criteria provided for establishing test pressure and duration.\

How Is The Inspection Frequency According to API 570?

Under API 570 rules, inspection schedules for piping systems are divided into circuits, which are further categorized into classes #1 through #4.

These classes are arranged according to risk level, with #1 representing the highest risk. The greater the risk posed by the piping system and its pressure-relieving components, the more often inspections are required.

Class #1: Highest Risk Potential

Requires Ultrasonic Thickness Test (UTT) and Visual External Inspection every five years.

Class #2: Moderate Risk Potential

Requires UTT every 10 years and Visual External Inspection every five years.

Class #3: Lower Risk Potential

Requires UTT and Visual External Inspection every 10 years.

Class #4: Minimal Risk Potential

Inspections are optional for this class.

What Is API 570 Certification?

API 570 certification validates piping inspectors who have a broad knowledge base relating to maintenance, inspection, alteration, and repair of in-service metallic piping systems. The API 570 examination assesses the piping inspectors’ knowledge in the related area including performing piping inspection.
