24-Hour Emergency Refractory Repair: Critical Failure Averted

An oil production facility experienced a sudden catastrophic refractory failure in their primary combustion chamber. A thermal shock event caused a section of the 9-inch castable lining to spall, exposing the carbon steel shell to direct flame impingement. Internal shell temperatures were rising toward the 800°F threshold, at which point structural integrity would be compromised, necessitating a full vessel replacement. Every hour of delay increased the risk of a total loss event.

Our emergency response team was mobilized and on-site within 4 hours of the initial call. We utilized rapid-cure, low-cement castable refractory materials rated to 2,800°F, combined with specialized pneumatic gunning equipment to bypass traditional form-and-pour installation methods. Our technicians worked in continuous 12-hour shifts to complete the full reline and structural reinforcement. Ultrasonic thickness testing (UTT) was performed on the shell to verify structural integrity before restart authorization.

• Completed full structural repair and refractory reline within 24 hours of team arrival on-site.
• Prevented an estimated $1.2M in lost production revenue from an extended multi-day shutdown.
• UTT confirmed shell integrity with zero areas of concern, enabling safe and immediate restart.
• Zero safety incidents recorded during the emergency repair operation.
