This document is based on the PAS55 asset management standard of the British Standards Institution, the Center for Chemical Process Safety (CCPS) of the American Institute of Chemical Engineers "Guidelines for Asset Integrity Management" and the ISO 55000 international asset management standard family as a reference, drawing on Sinopec, PetroChina, the national pipeline network, etc: Based on the excellent experience in plant integrity management, it is compiled based on the basic national conditions of my country's petrochemical equipment integrity management: this document It standardizes the content, main technical methods and requirements of the integrity management of the complete set of equipment, and clarifies the risk management of the whole life cycle of the complete set of equipment: Supporting technologies, application conditions, and analysis procedures provide a basis for enterprises to carry out integrity management of complete sets of equipment under the guidance of factory integrity management: It is of great significance to ensure the safe, economical and efficient operation of the complete set of equipment: Plant Integrity Management

1 Scope

China's national standard for the integrity management of process units. Integrity management extends beyond the individual pressure vessel or pipeline to the operating unit as a whole - a distillation train, a reactor section, a compressor house - and its premise is that the reliability of a plant is a property of the system rather than of its components. A unit whose every item has passed its inspection can still be unfit for service if the inspection intervals were set without regard to the actual degradation mechanisms, if the corrosion loops were drawn wrongly so that a line was assessed against the wrong fluid, or if a change was made without anyone reassessing what it affected. The standard sets out the framework: identifying the mechanisms, defining the assessment, setting intervals by risk, and closing the loop so that what an inspection finds changes what is inspected next.

This document specifies the static equipment (pressure vessels, atmospheric storage tanks, industrial pipelines, furnace tubes, valves, etc:) Contents, methods and requirements of life cycle integrity management of dynamic equipment (pumps, compressors, fans, etc:), instrumentation systems, and electrical equipment, including Integrity management content of equipment design, manufacturing and installation, commissioning and operation, decommissioning and scrapping: This document is applicable to the integrity management of oil refining, chemical, and coal chemical complete sets of equipment, as well as the integrity management of oil and gas gathering stations and oil reserve bases: Can refer to use:
