API 570 Piping Inspection Code โ Frequently Asked Questions
Authoritative answers about API 570 Piping Inspection Code, inspection intervals, qualifications, RBI, and ISO Xpert consulting.
What is API 570?
API 570 is the American Petroleum Institute's Piping Inspection Code covering the in-service inspection, rating, repair, and alteration of piping systems used in the petroleum refining and chemical process industries. It establishes inspection intervals, acceptable inspection methods, corrosion monitoring requirements, fitness-for-service evaluations, and repair and alteration procedures for in-service piping.
What are the piping circuit classes in API 570?
API 570 classifies piping circuits into three classes based on safety and environmental risk. Class 1 includes the most severe service piping such as hydrogen, flammable materials near ignition sources, strong acids, and high-pressure/temperature systems โ requiring the shortest inspection intervals (not to exceed 5 years external or 3 years for thickness measurement, or half the remaining life). Class 2 is general process service piping with maximum 10-year external and 5-year thickness intervals. Class 3 covers low-risk service piping with maximum 10-year intervals for both external and thickness inspection.
What is the significance of injection points in API 570 piping inspection?
Injection points are locations where chemicals, water, or other substances are injected into a piping system. They are critical inspection locations under API 570 because the mixing of injected fluids with process fluids can cause accelerated corrosion, erosion, or other damage mechanisms. API 570 requires enhanced inspection at injection points, typically within 12 inches (300 mm) upstream and 25 pipe diameters downstream of the injection point, at intervals not to exceed half those of the surrounding circuit.
What is a dead leg in piping and why does API 570 require special inspection?
A dead leg is a section of piping that normally has no or minimal flow, such as bypasses, stubs, sample connections, or instrument connections. Under API 570, dead legs receive special inspection attention because the lack of flow can allow stagnant liquids to accumulate, concentrate corrosive species, and cause accelerated corrosion that is not representative of the main flowing circuit. Dead legs shall be included in the inspection programme and monitored for the specific damage mechanisms applicable to their service.
Can ISO Xpert help develop an API 570 piping inspection programme?
Yes. ISO Xpert provides API 570 piping inspection programme gap analysis, inspection procedure development, RBI implementation, piping circuit classification review, injection point and dead leg surveys, inspector qualification guidance, and training for piping inspection professionals.
