What is API 570?
The global standard for in-service piping inspection
API 570 is the American Petroleum Institute's inspection code for in-service piping in petroleum and chemical facilities. It governs the inspection, repair, alteration, and rerating of metallic piping systems that have been placed in service — complementing the construction code ASME B31.3.
The matching individual certification, Certified API 570 Piping Inspector, is one of the most internationally recognised credentials in plant integrity work. Refinery operators, petrochemical plants, LNG terminals, and third-party inspection firms (DEKRA, Applus+, Bureau Veritas, Intertek, SGS) maintain large populations of certified inspectors because the credential is often a mandatory hiring filter on turnarounds and shutdowns.
Pair API 570 with API 510 (pressure vessels) and API 653 (storage tanks), and you hold the full "fixed equipment" inspector trio — a credential set that unlocks senior integrity roles and international day-rate work across the Gulf, North America, and South-East Asia.
What You Will Learn
A complete API 570 skillset — free on EveryEng
Six focused pillars covering the API 570 body of knowledge and every reference standard on the exam.
NDE Methods
Radiography (RT), ultrasonic testing (UT), magnetic particle (MT), and liquid penetrant (PT) — interpretation and acceptance.
Repair & Alteration
Weld repair procedures, temporary repairs (clamps, sleeves), alteration categories, and rerating methodology per API 570.
Codes & Standards
Deep dives into API 570, API 574 (inspection practices), API 577 (welding), API 578 (PMI), ASME B31.3, and ASME Section V.
Corrosion & Damage
All 20+ damage mechanisms in API 571 — CUI, sulfidation, HIC, amine cracking, high-temperature H₂ attack, and more.
Exam Preparation
Open-book document navigation drills, closed-book memorisation sets, and full-length timed mock papers.
Curriculum
11 modules — zero to exam-ready
Follow the full track or dip into any module. Every module awards its own CPD-accredited certificate.
