# API 570 Piping Inspection Code

> API 570, Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems, is the API code for metallic and FRP process piping after commissioning, defining piping service classes, inspection types and intervals, condition monitoring locations and repair rules.

## Key facts

- Piping is classed by consequence of failure (Class 1 highest); higher class means shorter maximum inspection intervals
- Thickness measurements at CMLs establish corrosion rates and remaining life per circuit
- Special attention to injection points, dead legs, corrosion under insulation and soil-to-air interfaces
- Widely applied in refineries, petrochemical and gas plants in Australia and New Zealand

Also known as: API 570 inspector, piping inspection code.

## The inspection company's scope

Thickness surveys, external visual, targeted advanced NDT (corrosion mapping, guided wave) and post-repair examination, all recorded per circuit and CML.

## API 570 work in AMPS

Piping circuits and CMLs can be modelled as assets and sub-assets in AMPS, each with a QR code and its own job history, so successive surveys for the same location are one scan away. All AMPS data is available to Power BI, which is how customers compare job or shutdown performance, costs and time allocation.
