In some petrochemical applications, turnaround teams still rely on conventional hex metal as a familiar anchoring solution. However, hex mesh installations are prone to refractory failure mechanisms such as break‑off, spalling, carburization, biscuiting, and bypass. They are particularly evident at corners, terminations, and tight geometries, where maintaining weld quality and continuity is difficult, and where local process conditions can further accelerate refractory degradation.
Petrochemical FCC units and their major components as Cyclones, Risers, Regenerator and Reactors demand anchoring systems that can withstand severe thermal cycling, abrasion, and difficult installation areas. The SILICON SpeedSeries addresses these challenges with two dedicated systems.
Use the guide below to determine the most suitable solution. Identify your unit and the corresponding failure mode. If you are unsure, please request a configuration recommendation.
Areas of application: Abrasion‑prone FCC Units, ducts and transfer lines; Coking and non‑coking services; Edges, corners, terminations, and tight geometries
By combining a primary SpeedHex® anchoring (SpeedHex® 3, SpeedHex® Mini, or SpeedHex® 6) with auxiliary components and Rapid Arc Welding (RAW) full‑fusion welding, the system helps prolong lining life and reduce unplanned shutdowns.
Areas of application: FCC Units, reactors and vessels, ducts and transition sections; Coking and non‑coking services.
The SpeedVee® System is designed for monolithic refractory linings where secure attachment, controlled movement, and reliable welding are critical. It offers dual alloy configuration. This system combines SpeedVee® anchors with auxiliary components like SpeedTab® and SpeedClip.
