Product Description

ASME SA179 Embedded Fin Tube with Al1060 Fin

I. Product Overview

This is an embedded (G-type) fin tube designed for industrial heat exchangers. The base tube is manufactured from ASME SA179 seamless low-carbon steel, offering good thermal conductivity and pressure resistance for heat transfer service. High-purity 1060 aluminum fins (Al ≥ 99.6%) are precisely embedded into grooves on the tube's outer wall. This mechanical bonding ensures excellent contact, minimizing thermal resistance and preventing fin loosening.Compared to plain tubes, it greatly increases the heat exchange surface area, significantly boosting overall thermal efficiency. It is ideal for condensers, coolers, and waste heat recovery units operating in moderate temperature and corrosive environments.

Range	99.60	0.35	0.05	0.03	0.03	0.05	0.03

Mechanical Properties (Base Tube)

Tensile Strength (min)	Yield Strength (min)	Elongation (min)
325 MPa	180 MPa	35%

Ⅲ. Comparison: Embedded Fin vs. L VS. Type Wound Fin for SA179 Tubes

Feature	ASME SA179 (Seamless)	ASME SA106 Gr.B (Seamless)
Primary Use	Heat Exchangers & Condensers	High-Temperature Pressure Piping
Form Factor	Tube (Specified by OD & BWG)	Pipe (Specified by NPS & Schedule)
Manufacturing	Cold Drawn (Better surface finish)	Hot Finished (Rougher surface)
Carbon Content	Low Carbon (0.06% - 0.18%)	Medium Carbon (Max 0.30%)
Tensile Strength	Min 325 MPa (Lower)	Min 415 MPa (Higher)
Yield Strength	Min 180 MPa	Min 240 MPa
Ductility	Excellent (Better for grooving/finning)	Moderate
Heat Transfer	Slightly higher due to thinner walls	Lower due to heavier wall thickness
Finning Suitability	Ideal for Embedded (G) Fins	Suitable, but harder to groove
Price	Higher (Due to cold drawing process)	Lower (Mass-produced hot finish)

Ⅳ. Key Applications

• Air-Cooled Heat Exchangers (AFC): Widely used in oil refineries and petrochemical plants for cooling process fluids, especially where high thermal stability is required.

• Power Generation: Applied in steam condensers, feed-water heaters, and Heat Recovery Steam Generators (HRSG) for efficient energy recovery.

• High-Temperature Services: Ideal for operating environments up to 400°C - 450°C, as the "G-fin" design prevents fin loosening during thermal expansion.

• Chemical Processing: Used in reactors and specialized heat transfer equipment where precise temperature control and seamless tube reliability are critical.

• Boiler Systems: Integrated into industrial boilers as economizer tubes to preheat water using flue gas, maximizing fuel efficiency.

• Oil & Gas Midstream: Utilized in gas compression stations and dehydration units for cooling natural gas.

The 13Cr pins add some cost, but for sour service in furnaces, it's worth it. Already seeing longer run times between turnarounds compared to before.

With high firebox temps and some sour gas in the mix, regular carbon tubes don't last. These have been solid.

Helpful (2)

the SS409 pins resist sulfur corrosion better than carbon steel pins we used earlier. In furnace service, that means longer runs between maintenance.
