ASME SA335 P9 Studded Longitudinal Finned Tube Stainless Steel For Heater Furnace

A studded finned tube is a high-performance heat exchanger component featuring welded studs that significantly enhance heat transfer efficiency between fluids and gases. The stud design maximizes surface area while maintaining a compact footprint, making it ideal for demanding industrial applications.

The 9% Cr-1% Mo composition provides exceptional high-temperature strength and oxidation resistance, while low carbon content ensures good weldability.

Supplied in normalized & tempered condition for optimal strength and ductility. Retains strength up to ~650°C (1200°F) and requires preheating (~200-300°C) with post-weld heat treatment (PWHT) to prevent cracking.

• Increased Surface Area: Studs significantly enhance heat transfer surface for superior thermal efficiency
• Compact Design: Maximizes heat transfer capacity without increasing physical footprint
• High-Temperature Performance: Resilient in extreme conditions up to 650°C (1200°F)
• Reduced Fouling: Smooth stud surfaces minimize deposit buildup compared to traditional fins
• Enhanced Durability: Superior erosion/corrosion resistance in harsh industrial environments

• Power Generation: Heat Recovery Steam Generators (HRSGs), Fluidized Bed Boilers, Superheaters
• Petrochemical: Fired Heaters, Catalytic Cracking Units (FCCU), Coker Units
• Waste Treatment: Waste-to-Energy Plants, Air Preheaters (APH)
• Chemical Processing: Sulfuric Acid Plants, Ammonia Production, Syngas Coolers
• Heavy Industry: Cement Clinker Coolers, Blast Furnace Gas Ducts
