Coke drum services address coker-specific challenges with advanced weld automation

For decades, WSI has provided advanced coke drum services and repair options to address prevalent coke drum failures. Our unique process uses highly engineered weld metal overlay to modify the vessel’s structure, mitigating bulging and cracking of the pressure boundary shell, support skirt-to-shell interface weld area, and lower cone cladding damage. As the industry’s largest provider of structural repairs for coke drums, WSI excels in coke drum maintenance and coker drum repair.

Our process involves installing a highly engineered weld metal overlay on existing vessels and modifying their structure to mitigate bulging and cracking caused by low-cycle fatigue.

Precision weld automation for optimal coker drum repair

Our tightly controlled welding parameters, managed by closed-loop automated welding systems, employ controlled deposition techniques (temper bead) to eliminate the need for post-weld heat treatment. This approach has been successfully implemented in over 100 coke drums worldwide, ensuring reliable coke drum automated weld overlay repairs.

For support skirt crack repairs, WSI uses proprietary welding processes to replace critical welds and install new skirt sections without post-weld heat treatment. This method has been proven superior, with dozens of successful skirt repairs across the industry.

WSI engineered solutions for coke drum reliability

Delayed coking, which has been in use since the 1950s, subjects components to significant temperature and pressure fluctuations, causing low cycle fatigue failures in coker drums. These drums are costly to replace and are critical assets, making life extension, shortened turnaround cycles, and improved reliability and safety essential.

As the largest provider of structural repairs for coke drums, WSI extends life, shortens turnaround cycles, and enhances the reliability and safety of these critical assets through our automated coker drum weld overlay.
