Seamless Studded Fin Tube

Product Description

1. What is ASTM A213 T9 Studded Fin Tube?

ASTM A213 T9 Studded Fin Tube is a high-temperature heat transfer component engineered for extreme thermal and corrosive service. It consists of a seamless chromium-molybdenum alloy steel base tube (ASTM A213 T9) with stud-type fins resistance-welded perpendicularly to the surface. This robust construction maximizes heat flux in high-ash/flue gas environments (up to 600°C/1,112°F), offering superior oxidation resistance and 3x longer life than carbon steel tubes in waste heat boilers, reformers, and fired heaters.

3. Key Applications & Competitive Advantages

· Refinery Heaters: Convection sections in CDU/VDU heaters (resists sulfidation).

· Chemical Reformers: Syngas coolers in methanol/ammonia plants.

· Waste Heat Recovery: Boilers in cement/steel mills (handles >80g/Nm³ fly ash).

· Power Generation: SCR system heat exchangers for coal-fired plants.

· Petrochemical: Cracking furnace convection tubes.

4. Why This Solution Dominates:
· 10-Year Lifespan: Withstands 650°C cyclic operation per NACE RP0492.
· Ash Erosion Resistance: Stud spacing blocks ash buildup – 40% lower fouling vs. helical fins.
· Cost Saving: 35% lower OPEX than refractory-lined carbon steel tubes.
· Customization: Stud height (15–40mm), diameter (3–8mm), and pitch optimization.
