An emergency shutdown occurred due to hex spalling and cracking on the riser feed nozzle shields, jeopardizing the possibility of making it to the official Turnaround early 2025. SILICON SpeedHex ® was requested because of its reputation for both quality and speed of installation, using Rapid Arc Welding.
Initially, SILICON SpeedHex® was requested for the quality and installation . However, upon evaluation, it was deemed too large for this area. Consequently, a smaller hex pattern was needed. SpeedHex® Minis emerged as the perfect solution and were promply approved for installation to meet the deadline.
To expedite installation, a day and night shift rotation involving three crew members was implemented for optimal efficiency. Additionally,
SpeedVee® anchors were installed in the lower regenerator sidewalls.

The SpeedHex®3 is designed to remove the direct path to the shell for gasses and enable continuous refractory protection across the surface of the shell, rather than only cookies/small pockets of protection and allows for more refractory material to flow through, over, under AND in between each cell.
SpeedVee® has outperformed conventional V anchors in every vessel they have been installed in. They're safer, more reliable and more cost-effective by having huge positive schedule impacts. With these full fusion welds, V anchors are no longer just little refractory attachments - they become mechanical upgrades, with refractory features.
