Product Overview

Ensure optimal thermal efficiency and structural longevity in your industrial furnaces with our premium ASTM A351 Gr. HK40 Intermediate Tube Sheet. Engineered specifically for fired heaters, reformer furnaces, and petrochemical processing units, this high-temperature alloy casting is designed to support, guide, and protect vital radiant tubes under extreme operating conditions.

Why Choose Our HK40 Intermediate Tube Sheets?
  • Exceptional Heat Resistance: Manufactured from ASTM A351 Grade HK40 (Austenitic stainless steel), our tube sheets deliver unmatched structural stability at temperatures up to 1050 °C (1920 °F).
  • Superior Creep & Carburization Resistance: The specialized chemical composition (approx. 25% Chromium and 20% Nickel) ensures maximum durability against thermal cycling, carburization, and oxidation in harsh process environments.
  • Precision Casting & Machining: Produced using advanced static or centrifugal casting techniques, resulting in a fine-grained, high-density microstructure free from casting defects like porosity and slag inclusions.
  • Custom OEM Capabilities: Fully machined and fabricated according to your exact engineering blueprints, ensuring perfect alignment and seamless integration into your existing fired heater or cracking furnace.
