For decades, WSI South America 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.
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 South America 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.
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 reliable provider of structural repairs for coke drums, WSI South America extends life, shortens turnaround cycles, and enhances the reliability and safety of these critical assets through our automated coker drum weld overlay.
With our extensive experience and cutting-edge technology, WSI South America provides industry-leading coker weld overlay repair and coke drum services, ensuring the highest quality and reliability for your critical assets.
WSI’s proprietary HF40™ overlay is a Fe-Cr-C-Zr hardfacing alloy with approximately 20% chromium (Cr) that provides exceptional resistance to erosion and wear as well as erosion/corrosion attack.
With roots dating back to the 1700’s, steam-generating boilers have evolved greatly based on industrial and residential demand. Learn how WSI's advanced welding technologies have kept pace.
Because of the significant deposition rates achievable with this technology, justification for repair at sea vs. dry-dock was clear.

To ensure the longevity and performance of RIG-A-LITE fixtures, no chemicals that can damage metal, aluminum, glass, or polycarbonate should be used to clean or come into contact with the luminaire or lens surfaces. For any concerns or questions about chemical compatibility, please contact RIG-A-LITE Customer Service.
Polycarbonate experiences noticeable deterioration when exposed to certain chemicals —whether through direct contact, airborne mist, or vapor. These chemicals can compromise the luminaire lenses and lead to defects and product failures such as:
These types of damage are not covered under warranty.
If exposure to any of these chemicals is unavoidable, we recommend alternative lens materials such as acrylic, silicone, or borosilicate glass. If you notice visible deterioration to an existing product, it is crucial to replace the product immediately with a more suitable option.
Any of the following chemicals is potentially detrimental to polycarbonate lens material*:
