Analysis of the Relationship between Mechanical Integrity Management and Equipment Integrity Management I. Definition of Mechanical Integrity Management Mechanical Integrity (MI) is one of the core elements of Process Safety Management (PSM). It aims to ensure that critical equipment maintains a safe and reliable operational state throughout its lifetime, by combining technical improvements with standardized management practices, thereby preventing safety accidents caused by equipment failures. Its management scope covers high-risk equipment such as pressure vessels, safety instrumented systems, and fire protection facilities, emphasizing risk-based approaches (such as FMEA and RCM) for maintenance. II. Contents and Requirements for Mechanical Integrity Management 1. Scope of management: Includes all life-cycle activities such as equipment installation, maintenance, inspection, disposal, modification, and training. 2. Technical requirements: Ø Use risk control methods such as Failure Mode and Effects Analysis (FMEA) and Reliability-Centered Maintenance (RCM) ； Ø Conduct regular inspections on special equipment, such as pressure vessels and safety valves. 3. Regulatory standards: Ø It is necessary to comply with the provisions regarding mechanical integrity in AQ 3034-2010 \"Guidelines for the Implementation of Process Safety Management in Chemical Enterprises\" ； Ø Comply with the framework requirements for equipment management systems as specified in standards such as GB/T 44692.1. III. Contents of Equipment Integrity Management Equipment integrity management is centered on mechanical integrity, but its scope is broader: 1. Full life cycle management: From equipment design, procurement, installation to disposal, technical improvements and standardized management are required to ensure its physical and functional integrity. 2. Systematic approach: Ø Build a management system based on risk thinking, covering equipment lists, spare parts management, operating procedures, etc ； Ø Continuously optimize management processes by integrating a dynamic improvement mechanism. 3. Key elements: include equipment identification and classification, preventive maintenance, anomaly management, personnel training, etc. IV. The relationship between mechanical integrity management and equipment integrity management 1. Subsidiary relationship: Mechanical integrity management is a core component of equipment integrity management; especially within the PSM framework, it focuses on ensuring the reliability of high-risk equipment. 2. Scope differences: Ø Mechanical integrity focuses on the safety protection of process equipment (such as pressure vessels, safety instrument systems) ； Ø Equipment integrity covers a wider range of asset types (such as electrical systems, piping, etc.), with an emphasis on systematic management throughout the entire life cycle. 3. Coordination: Both are based on risk control methods; they need to achieve their objectives through a combination of technical measures and management standards, and they share tools such as FMEA and RCM.
