Expansion Joint for FCC Unit Reactor to Fractionator Line

MACOGA has successfully designed, manufactured, and delivered a high-performance metallic expansion joint for a Fluid Catalytic Cracking (FCC) unit, specifically for the transfer line between the reactor and the fractionator.

This critical component is engineered to withstand the extreme operating conditions of the FCC process, ensuring safe and reliable absorption of thermal expansion and vibration.

Key Specifications:

• Nominal diameter: DN 900
• Design pressure: 3.4 barg
• Test pressure: 6.72 barg
• Design temperature: +543 °C
• Medium: Steam + Hydrocarbon vapors
• Construction code: EJMA 10th Edition
• Certification: CE Marking – Module H
• Post-weld heat treatment: Full cycle per ASME VIII-1
• Non-destructive testing: 100% RT, LPT, MT, UT on critical welds

This expansion joint was manufactured under strict quality protocols to ensure performance under highly demanding conditions, typical of FCC process units.
