Mechanical Integrity

What is Mechanical Integrity (MI)?

MI is a management system that addresses the quality of critical process equipment at every stage of the asset life cycle from the design of new facilities to maintenance management to decommissioning.


A robust MI system enhances product quality and reduces the overall cost of finished goods through increased availability (onstream time) and consistency.

MI includes equipment such as pressure vessels, relief devices, piping, tanks, and associated hardware. Essentially anything on the P&ID is included in MI!

Inspections, testing, auditing, and overall quality processes are just some of the tools designed to make an effective MI management system.
