Remaining Life Assessment of Coker Heater Tubes

Presented By

Atul Ganpatye - Stress Engineering Services, Inc.

Conference: Mumbai 2016

courtesy of SESRemaining life assessment of coker heater tubes will be discussed, with emphasis on insights gained from the accelerated creep testing of service-exposed tube samples. The impact of service conditions, tube removal procedures for testing, and assessment methodology on the results will be discussed. For remaining life predictions, the industry has traditionally relied on the Larson-Miller parameter, though the MPC Omega method has gained industry-wide acceptance in the recent years partly due to its inclusion in API 579-1. The applicability of the two methodologies will be discussed in relation to accelerated creep testing of 9Cr-1Mo steel and 347H stainless steel, two of the commonly used tube materials in Coker heaters.
