ASTM A179 Carbon Steel Seamless Tube Low Fin Tube For Heat Exchanger
Product Description
ASTM A179 carbon steel seamless tube low fin tube is manufactured by rolling external fins directly from the base tube wall. Unlike high fins, the low fins are shorter in height but provide increased surface area, while maintaining the mechanical strength of the seamless tube. This type of fin tube is widely applied in heat exchangers, condensers, and coolers where compact size and efficient heat transfer are required.

|---|---|---|---|---|
| Content (%) | 0.06–0.18 | 0.27–0.63 | 0.035 | 0.035 |
| Property | Requirement |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
| Hardness | ≤ 72 HRB |
Compact design: increased surface area without enlarging tube bundle size
Stronger bonding: fins are an integral part of the tube (not attached separately)
Good heat transfer efficiency: especially suitable for gas–liquid and liquid–liquid heat exchange
Durability: seamless structure ensures high reliability under high temperature and pressure conditions
Enhanced heat transfer compared with plain tubes
No risk of fin detachment since fins are extruded from the base tube
Cost-effective and efficient solution for compact heat exchanger design
Long service life with stable performance in demanding environments
Applications
Heat exchangers in power plants, petrochemical plants, and refineries
Condensers in refrigeration and air conditioning systems
Oil & gas processing units
Boiler and economizer equipment
