API 570 provides the framework for the in-service inspection, rating, repair, alteration, and rerating of process piping systems operating throughout the petroleum, petrochemical, and process industries.
Effective piping programs depend upon understanding degradation mechanisms, operating conditions, inspection history, and risk exposure.
API 570 inspection programs commonly integrate damage mechanism reviews and risk-based inspection methodologies to support mechanical integrity decision-making.
At Advanced Inspection Solutions, process piping inspections are not developed around pipe size, service class, or inspection intervals alone.
T
hey are built around understanding:
AIS develops inspection strategies that combine:
The objective is simple:
Inspect the locations most susceptible to degradation
before deterioration becomes failure.
Piping systems often experience different degradation patterns than pressure vessels due to flow conditions, turbulence, injection points, dead legs, and changing process chemistry.
AIS utilizes API 571 principles to identify credible damage mechanisms that may affect specific piping systems.
Potential degradation mechanisms may include:
Understanding damage mechanisms is the foundation of effective inspection planning.
Effective API 570 programs begin by defining piping systems.
AIS assists clients with organizing piping assets into manageable inspection systems that consider:
Process Service
Operating Conditions
Consequence Considerations
System classification helps establish inspection priorities and supports long-term integrity management.
AIS develops Inspection Test Plans specific to each piping system and corrosion circuit.
Typical considerations include:
Process Conditions
Process Chemistry
Mechanical Features
Historical Data
This approach maximizes inspection effectiveness while reducing unnecessary inspection activity.
AIS integrates API 580 Risk-Based Inspection methodologies into process piping inspection programs.

Inspection programs are only as effective as the process conditions supporting them.
AIS encourages owner-operators to establish Integrity Operating Windows for variables known to influence piping degradation.
Examples include:
Monitoring operating conditions helps identify changing degradation risks before failures develop.
Many piping inspection programs focus primarily on inspection intervals.
AIS focuses on:
By combining API 570 inspection practices with API 571 damage mechanism identification and API 580 risk-based methodologies.
AIS develops inspection strategies that support safer operations, improved reliability, and more informed integrity decisions.
"Effective piping integrity begins with understanding where degradation develops, why it occurs, and what must be protected before failure happens."
