Product Description

Stainless Steel Seamless Pipe HFW Serrated Fin Tube ASTM A312 TP304H, for Convection Coil

Key Features:

his is a high-performance high frequency welded (HFW) serrated fin tube made from ASTM A312 TP304H stainless steel base tube, with stainless steel (SS304) serrated fins welded on the outer surface. The serrated fins are precisely cut to increase turbulence and improve thermal efficiency.

Technical Specifications:

Property	Base Tube (ASTM A312 TP304H)	Fin Material (SS304)
Outer Diameter (OD)	19.05 mm - 50.8 mm	Customizable based on design
Wall Thickness	2.0 mm - 5.0 mm	-
Fin Thickness	-	0.3 mm - 0.5 mm
Fin Pitch	-	5 - 10 fins per inch
Fin Height	-	10 mm - 25 mm
Fin Attachment	High-Frequency Welded

Chemical Composition:

Element	ASTM A312 TP304H (Base Tube)	SS304 (Fin Material)
Carbon (C)	≤ 0.04%	≤ 0.08%
Manganese (Mn)	≤ 2.00%	≤ 2.00%
Phosphorus (P)	≤ 0.045%	≤ 0.045%
Sulfur (S)	≤ 0.030%	≤ 0.030%
Silicon (Si)	≤ 1.00%	≤ 1.00%
Chromium (Cr)	18.00 - 20.00%	18.00 - 20.00%
Nickel (Ni)	8.00 - 11.00%	8.00 - 10.50%

Mechanical Properties:

Property	ASTM A312 TP304H (Base Tube)	SS304 (Fin Material)
Tensile Strength	≥ 515 MPa	≥ 515 MPa
Yield Strength	≥ 205 MPa	≥ 205 MPa
Elongation	≥ 35%	≥ 40%

Advantages:

High Temperature Resistance: TP304H has elevated carbon content, making it more stable at high temperatures.
Corrosion Resistance: Excellent resistance to oxidation and various corrosive environments.
Improved Heat Transfer: Serrated fins break the boundary layer, increasing turbulence and heat exchange.
Durability: HFW process ensures strong fin-to-tube bonding, with minimal thermal stress issues.
Reduced Fouling: Stainless steel surfaces resist fouling and scale formation better than carbon steel.

Applications:

Convection Coils: Ideal for furnaces, boilers, and heat exchangers where high-efficiency heat transfer is required.
Industrial Heating Systems: Used in power plants, chemical plants, and refineries where heat recovery and thermal management are crucial.
Air-Cooled Heat Exchangers: Effective in air-cooled heat exchangers for HVAC systems and cooling towers where compactness and efficiency are essential.
Energy Recovery Systems: Commonly used in waste heat recovery and energy-efficient systems where convection heat transfer is needed to maximize energy savings.

Tube ends were clean, dimensions accurate. Our fitters didn't complain about fit-up.

Been running about 6 months now in cyclic service. No leaks, no failures. Heat transfer still where it should be.

We checked a few before installation — wall thickness consistent, roundness good. Welded in without problems.
