API 570 - Piping Inspection Code

API 570, Piping Inspection Code, Fourth Edition, is an inspection code developed and published by the American Petroleum Institute (API) that covers the in-service inspection, repair, alteration, and rerating activities for piping systems and their associated pressure relieving devices in the petroleum and chemical process industries. It applies to metallic piping and those plastic ones that are either fiberglass reinforced (FRP) or glass reinforced (GRP). The first edition of the code was originally published in October of 1998 and the most recent edition was published on February 1, 2016.

API 570 establishes requirements and guidelines for maintaining the safety and mechanical integrity of piping systems after they have been placed into service/commissioned. While it was primarily intended for those systems in the petroleum and chemical process industries, this code can be applied to any piping system where practical.

This code also covers pipelines that carry process fluids, hydrocarbons, and other flammable or toxic fluids. Some specific fluids covered include petroleum and chemical products, natural gas, flare systems, sour water, and high pressure gasses. API 570 specifically does not govern the construction of pipelines or set forth any standards relating to them before they are placed into service.
