Metallurgy Grade & Material Selection
Choosing the right alloy prevents high-temperature corrosion and creep rupture in the radiant section firebox and convection zones. We select materials based on your specific process temperature and fluid chemistry:
Carbon Steel: Used for low-temperature structural components and external casing.
Low Alloy Steels : Ideal for moderate temperature process tubes resisting sulfur corrosion.
High Alloy Steels & Stainless (e.g., 304H, 316H, 347H, HK40): Deployed in high-severity zones like ethylene cracking furnace coils to withstand extreme heat and oxidation.
Key Component Engineering in Petrochemical Furnaces
We engineer every petrochemical furnace to withstand extreme thermal stress while maintaining maximum uptime. By focusing on high-grade metallurgy and precision fluid dynamics, our fired heaters deliver uniform heat transfer and long-term structural integrity.
Radiant Section Firebox
The radiant section firebox is the heart of the heating process. We design this zone for optimal spatial layout to ensure uniform heat flux and absolute tube flame impingement prevention.
Tube Arrangement
Configured for maximum exposure to radiant heat.
Metallurgy
High-alloy stainless steels chosen for oxidation resistance.
Design Focus
Elimination of hot spots to extend process tube life.
Convection and Shield Section
Positioned above the firebox, this zone recovers residual heat from the flue gas to boost overall thermal efficiency.
Convection section finned tubes maximize the surface area for heat recovery.
Studded or bare tubes are used in the shield section to handle the initial impact of hot flue gases.
Optimized tube cleaning access points minimize maintenance downtime.
