Piping systems are among the most critical assets in refineries, petrochemical plant, and other process facilities. These systems transport hazardous and high-temperature fluids, making their integrity essential for safe and reliable operations. As a result, companies rely on qualified piping inspectors who understand how to inspect, assess, and maintain piping systems throughout their service life.

The API 570 certification, administered by the American Petroleum Institute (API) through its Individual Certification Program (ICP), is one of the most recognized credentials for piping inspectors worldwide. However, candidates cannot simply register for the examination. They must first meet specific eligibility requirements related to education, industry experience, and technical knowledge.

This guide explains the API 570 certification requirements and helps you determine whether you are ready to pursue certification.

What Are the API 570 Certification Requirements?

To qualify for API 570 certification, candidates generally need to meet the required education and experience criteria, possess relevant piping inspection experience, understand the applicable codes and publications, and be familiar with the certification and recertification requirements.

1. Meet the Education and Experience Requirements

API uses an eligibility matrix that combines formal education and relevant industry experience. In general, candidates with higher educational qualifications require fewer years of experience to become eligible for certification.

Bachelor’s Degree Path

Candidates with a bachelor’s degree in engineering or technology require:

• Minimum one year of experience in the supervision or performance of inspection activities as described in API 570.

Degrees commonly associated with this pathway include:

• Mechanical Engineering
• Chemical Engineering
• Materials Engineering
• Metallurgical Engineering
• Industrial Engineering

Two-Year Technical Degree Path

Candidates with a two-year technical degree or engineering technology diploma require:

• Minimum two years of experience in the design, fabrication, repair, operation, or inspection of piping systems.
• At least one year must involve supervision or performance of inspection activities described in API 570.

High School Diploma or Equivalent Path

Candidates with a high school diploma or equivalent qualification require:

• Minimum three years of experience in the design, fabrication, repair, operation, or inspection of piping systems.
• At least one year must involve supervision or performance of inspection activities described in API 570.

This pathway is common among experienced inspectors, technicians, and maintenance personnel who have built their expertise through hands-on work.

No Formal Education Path

API also provides a pathway for candidates without formal educational qualifications.

These candidates require:

• Minimum five years of experience in the design, fabrication, repair, operation, or inspection of piping systems.
• At least one year must involve supervision or performance of inspection activities described in API 570.

This pathway recognizes professionals who have gained substantial technical knowledge through extensive field experience.

2. Build Experience in Piping Inspection and Integrity Management

Meeting the education requirement alone is not enough. Candidates also need practical experience related to piping inspection and integrity management.

API places significant emphasis on field experience because piping inspectors are expected to make decisions that directly affect equipment reliability and process safety.

Inspection and Integrity Management Experience

Examples of qualifying activities may include:

• Performing in-service piping inspections
• Developing inspection plans
• Conducting remaining life assessments
• Participating in mechanical integrity programs
• Preparing inspection reports
• Supporting fitness-for-service evaluations

Experience involving process piping systems is generally considered highly relevant.

Engineering and Design Experience

Certain engineering activities may also contribute to eligibility if they involve piping systems and integrity management.

Examples include:

• Piping design review
• Corrosion assessments
• Failure investigations
• Inspection planning support
• Technical evaluations of piping systems
• Repair recommendations

The key consideration is whether the work contributes to understanding piping inspection and integrity management.

Operations and Maintenance Experience

Professionals working in operations and maintenance may also possess relevant experience if their responsibilities involve piping systems and pressure equipment.

Examples include:

• Turnaround inspections
• Shutdown activities
• Equipment condition assessments
• Maintenance planning
• Repair coordination
• Mechanical integrity activities

Experience That May Not Qualify

Not every maintenance or manufacturing role automatically meets API 570 requirements.

For example, experience that is primarily administrative or unrelated to process piping systems may not be considered sufficient.

Candidates who are unsure about their eligibility should carefully review the latest API ICP guidance before submitting an application.

3. Become Familiar with the Required Codes and Publications

API 570 certification candidates are expected to have a working understanding of the standards and publications referenced in the API 570 Body of Knowledge.

These publications form the technical foundation of piping inspection and integrity management.

API 570 Piping Inspection Code

API 570 is the primary standard governing:

• Inspection of in-service piping systems
• Repair of piping systems
• Alteration and rerating of piping systems
• Inspection intervals and assessment methodologies

Candidates should understand the principles and requirements contained in this standard because it serves as the basis for professional piping inspection practices.

API 574 Inspection Practices for Piping System Components

API 574 provides practical guidance on:

• Piping components and their functions
• Inspection methodologies
• Deterioration mechanisms
• Inspection planning
• Inspection techniques

It complements API 570 by helping inspectors understand how inspections are performed in real operating facilities.

API 571 Damage Mechanisms Affecting Fixed Equipment

Understanding damage mechanisms is essential because many inspection decisions depend on recognizing potential degradation.

API 571 discusses:

• Corrosion mechanisms
• High-temperature damage
• Mechanical damage
• Environment-assisted cracking
• Metallurgical degradation

A solid understanding of these topics helps inspectors identify risks before failures occur.

Relevant ASME and API Reference Publications

The API 570 Body of Knowledge also references additional standards and publications.

These may include selected sections from:

• ASME B31.3 Process Piping
• ASME Boiler and Pressure Vessel Code
• Other API standard and recommended practices

Candidates should review the latest Body of Knowledge published by API to determine which references are currently included in the examination scope.

4. Understand the Certification and Recertification Requirements

In addition to meeting the eligibility requirements, candidates should understand several administrative requirements before pursuing certification.

Application and Examination Fees

The API Individual Certification Program currently charges:

• Admin fee: USD 100
• Examination fee: USD 1125 per attempt

Because fees may change over time, candidates should always consult the latest information published by API.

Certification Validity Period

API 570 certification is valid for three years from the certification date.

To maintain an active certification status, inspectors must renew their certification before it expires.

Recertification Requirements

To maintain certification, inspectors are generally expected to:

• Renew their certification every three years.
• Demonstrate continued involvement in relevant inspection activities.
• Meet the latest API ICP renewal requirements.

Why Do API 570 Requirements Matter for Your Career?

The API 570 requirements are designed to ensure that certified inspectors possess both theoretical knowledge and practical experience.

Piping inspectors often make decisions that directly affect:

• Process safety
