Fixed Equipment

Stationary pressure-containing or structural equipment that remains permanently installed during normal operation.

Definition

Fixed Equipment refers to stationary assets that are permanently installed within industrial facilities and are not intended to rotate or move during normal operation. Typical examples include pressure vessels, heat exchangers, columns, reactors, storage tanks, boilers and piping systems. Fixed Equipment is a primary focus of mechanical integrity programs because degradation mechanisms can significantly affect safety and reliability.

Why It Matters

Managing the integrity of Fixed Equipment is essential for preventing loss of containment, maintaining regulatory compliance and ensuring safe plant operation.

In Practice

Inspection and maintenance activities for Fixed Equipment commonly include thickness monitoring, corrosion assessment, pressure testing, risk-based inspection and fitness-for-service evaluations.

Common Misuse

Fixed Equipment generally excludes rotating machinery and other equipment with significant moving components, which are typically managed using different maintenance and reliability approaches.
