Stress Engineering Services provides complete Coke Drum engineering support & analysis from life assessment and extension to the design of new drums. We draw on our extensive design, testing, analysis, measuring, and monitoring capabilities, along with our vast industry experience, to solve problems that improve plant integrity, safety, and profitability.
Our engineers and technicians are skilled in a variety of engineering disciplines and areas of expertise including failure analysis, metallurgy, acoustic-emissions testing, welding engineering, fitness for service, and forensics.
We assist plant operators with problems that arise from the harsh demands of refinery operation, shorter cycles, and zero-leak tolerances. We utilize state-of-the-art technology and more than 30 years of applied experience to monitor, assess and extend the life and reliability of delayed coker components, especially coke drums. Our objective is to give operators a better understanding of how to optimize daily operation, inspection, and maintenance practices to maximize both production and drum life.
Most existing coke drums were not designed for low-cycle fatigue, which did not become an issue until drums began operating on shorter cycles which increased local stresses above yield causing cracking. Even newer drums have experienced through-wall cracking in as little as 5 years. In addition, actual measured transients, which are much more severe than anticipated, were not used for these designs.
Stress Engineering personnel have been involved with the latest state-of-the-art coke drum design and can help you design and build drums that last.
We have the following downstream plant services:
