ASTM A335 P11 HFW Helical Serrated Finned Tube With Gr.11 Fins For Refinery

Product Specifications

Attribute	Value
Product Name	Alloy Steel HFW Serrated Finned Tube
Bare Tube Specification & Material	ASTM A335 P11
Bare Tube Length	Custom-sized
Bare Tube O.D.	25mm~219mm
Fin Material	Gr.11
Fin Height	0.375'' to 1.25''
Fin Segment	5/32'' or 5/16''
Fin Pitch	1 to 7 fins per inch
Application	Used in boilers, superheaters, economizers, fired heaters, reformers, and cracking furnaces

Product Description

The HFW Helical Serrated Finned Tube is a specialized heat exchange component where "HFW" denotes the High Frequency Welding process used to securely attach fins to the tube. This advanced welding technique ensures superior bond strength and thermal performance.

Key Features

Helical Design: Spiral fin arrangement enhances heat transfer efficiency through increased surface area and optimized fluid turbulence.
Serrated Fins: Notched edges maximize surface contact while accommodating thermal expansion, reducing stress and fouling.
Material Compatibility: Gr.11 fins match the ASTM A335 P11 tube composition for consistent high-temperature performance and corrosion resistance.

ASTM A335 P11 Material Properties

Chemical Composition (Weight %)

Element	Composition
Carbon (C)	0.05 - 0.15
Manganese (Mn)	0.30 - 0.60
Phosphorus (P) (max)	0.025
Sulfur (S) (max)	0.025
Silicon (Si)	0.50 - 1.00
Chromium (Cr)	1.00 - 1.50
Molybdenum (Mo)	0.44 - 0.65
Nickel (Ni) (max)	0.25
Vanadium (V) (max)	0.08

Note: Trace residual elements are restricted to maintain weldability and creep resistance.

Mechanical Properties

Property	Value
Tensile Strength (min)	415 MPa (60,000 psi)
Yield Strength (min)	205 MPa (30,000 psi)
Elongation (min, % in 50mm)	30%
Hardness (max, Brinell HBW)	179 HBW

Performance Characteristics

Heat treated in normalized + tempered condition for optimal strength
Maintains creep resistance up to 600°C (1,112°F)
Superior oxidation resistance due to chromium content
Impact testing available for low-temperature applications

Industrial Applications

Power Generation: Boilers, superheaters, and economizers in coal/gas-fired plants
Petrochemical: Fired heaters, reformers, and cracking furnaces
Chemical Processing: Heat recovery systems and reactors
Waste Heat Recovery: Industrial exhaust gas systems
HVAC: Large-scale industrial heating systems
