Centrifugal Compressor Overhauling

Overview

Introduction:

Centrifugal compressors are critical assets in oil, gas, and industrial operations where reliability, efficiency, and mechanical integrity directly impact production continuity. Overhauling represents a structured process to restore operational capability, ensure compliance with safety standards, and extend equipment lifecycle. This training program provides participants with advanced methodologies, inspection frameworks, diagnostic structures, and technical procedures for managing comprehensive centrifugal compressor overhauls. It emphasizes OEM guidelines, international standards, and engineering frameworks that support overhaul quality and performance assurance.
