High Temperature Ultrasonic Inspection of Pressure Vessels Piping Systems

摘要

Corrosion is one of the petrochemical industry's leading causes of equipment failure, repair, and replacement. Pressure vessels and piping systems and are subject to various attack mechanisms at elevated temperature, which if undetected can reduce their reliability. This can result in various safety issues, unscheduled shutdowns and catastrophic failures.Detecting corrosion and identifying corrosion rates while equipment is on-stream can assist Engineers and operational personnel in managing Plant shutdowns by forecasting equipment life and scheduling repairs and replacement. This paper describes the equipment and procedure to inspect pressure vessels and piping systems at elevated temperatures up to 385°C.
