Annotation

GENERAL APPLICATION

This inspection code covers the maintenance inspection, repair, alteration, and rerating procedures for pressure vessels used by the petroleum and chemical process industries. The application of this inspection code is restricted to organizations that employ or have access to an authorized inspection agency as defined in 1.2.4. Except as provided in 1.1.2, the use of this inspection code is restricted to organizations that employ or have access to engineering and inspection personnel or organizations that are technically qualified to maintain, inspect, repair, alter, or rerate pressure vessels. Pressure vessel inspectors are to be certified as stated in this inspection code. Since other codes that cover specific industries and general service applications already exist (for example, Sections VI, VII, and XI of the ASME Boiler & Pressure Vessel Code and the National Board Inspection Code), the industries that fit within the restrictions above have developed this inspection code to fulfill their own specific requirements.

This inspection code applies to vessels constructed in accordance with the API/ASME Code for Unfired Pressure Vessels for Petroleum Liquids and Gases, Section VIII of the ASME Code, and other recognized pressure vessel codes; to nonstandard vessels; and to other vessels constructed non-code or approved as jurisdictional special. This inspection code is only applicable to vessels that have been placed in service (including items further described in 1.1.2) and have been inspected by an authorized inspection agency or repaired by a repair organization as defined in 1.2.13.

Adoption and use of this inspection code does not permit its use in conflict with any prevailing regulatory requirements.
