Product Description

1.What is ASME SA335 P9 Alloy Steel HFW Solid Finned Tube with Carbon Fin?

ASME SA335 P9 HFW Solid Finned Tube with Carbon Fin is a high-temperature solution engineered for sulfur-rich environments. It combines a seamless chromium-molybdenum alloy steel base tube (ASME SA335 P9) with helically wound solid carbon steel fins bonded via high-frequency welding (HFW). This robust design delivers exceptional resistance to sulfidation and oxidation up to 600°C (1,112°F), making it ideal for refinery heaters, coker units, and high-sulfur flue gas applications.
