Product Description

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

Element	C	Mn	Si	Cr	Mo	P	S
%	0.05–0.15	0.30–0.60	0.50–1.00	1.00–1.50	0.44–0.65	≤0.025	≤0.025

Mechanical Properties – ASME SA335 P11

Property (Row)	Requirement
Tensile Strength (MPa)	≥ 415
Yield Strength (MPa)	≥ 205
Elongation (%)	≥ 30

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

Using these in mining cooling equipment under pretty rough conditions. They’ve been running for a month now and are super stable.

Good oxidation resistance, matches well with the T9. No scaling or thinning noticed.

Really good quality, the ASME SA249 standard is the real deal. I was worried about the fins getting crushed during the long trip, but the packaging was top-notch—not a single one was bent.
