Serrated Fin Tube ASME SA335 11 Alloy Steel Seamless Pipe For Heater

Serrated Fin Tube ASME SA335 11 Alloy Steel Seamless Pipe For Heater

Product Description
ASME SA335 P22 alloy steel seamless pipe serrated fin tube is manufactured by attaching serrated fin strips onto the base tube surface through high-frequency welding (HFW). The serrated fins are slit along their length to create small interruptions, which significantly improve turbulence and heat transfer efficiency. This makes the product highly suitable for Heat Recovery Steam Generator (HRSG) systems, boilers, and furnaces, where high-temperature and high-pressure performance is essential.

Chemical Composition – ASME SA335 P11

Mechanical Properties – ASME SA335 P11

Features of Serrated Fin Tube

• Enhanced heat transfer: serrated fins break boundary layers, improving heat transfer efficiency

• High-temperature resistance: P11 alloy steel performs well in elevated temperature environments

• Strong metallurgical bonding: HFW ensures excellent fin-to-tube attachment strength

• Durability: withstands oxidation, creep, and thermal cycling in HRSG systems

Advantages

• Enhanced heat transfer due to serrated fin geometry

• High-temperature resistance suitable for heater and furnace service

• Strong welded joint provides excellent durability

• Improved gas-side turbulence and efficiency

Applications

• Process Heaters

• Petrochemical Furnace Coils

• Waste Heat Recovery Units

• Refinery Heating Systems
