API 510 Pressure Vessel Inspection Code โ Frequently Asked Questions
Authoritative answers about API 510 Pressure Vessel Inspection Code, inspection intervals, qualifications, RBI, and ISO Xpert consulting.
What is API 510?
API 510 is the American Petroleum Institute's Pressure Vessel Inspection Code covering the in-service inspection, rating, repair, and alteration of pressure vessels used in the petroleum refining and chemical process industries. It establishes inspection intervals, acceptable inspection methods, corrosion monitoring requirements, fitness-for-service evaluation, and repair and alteration procedures for in-service vessels.
What is the maximum inspection interval for internal inspection under API 510?
Under API 510, the maximum interval for internal or on-stream inspection is 10 years, or half the remaining corrosion life of the vessel, whichever is less. For vessels subject to risk-based inspection (RBI), this interval may be extended based on a documented RBI analysis, but shall not exceed 20 years for external inspection and 10 years for internal inspection without RBI justification.
What is Risk-Based Inspection (RBI) in the context of API 510?
Risk-Based Inspection (RBI) under API 510 is a systematic process for assessing the likelihood and consequences of failure of pressure vessels to prioritise and optimise inspection resources. An RBI analysis considers damage mechanisms, historical inspection findings, operating conditions, fluid toxicity, and consequence of failure to determine appropriate inspection intervals, methods, and extent.
Who is qualified to perform API 510 inspections?
API 510 inspections must be performed by or under the supervision of a Pressure Vessel Inspector who is certified in accordance with API 510. Inspectors may be employed by the owner/operator or by an Authorised Inspection Agency (AIA). The AIA inspector holds a valid API 510 certification (APICE). Pressure Vessel Engineers may also be involved in fitness-for-service evaluations and alteration approvals.
Can ISO Xpert help with API 510 inspection programme compliance?
Yes. ISO Xpert provides API 510 inspection programme gap analysis, inspection procedure development, RBI implementation support, inspector qualification guidance, and training for pressure vessel inspection professionals. Contact us at info@iso-xpert.com or call +44 7853 109840.
