Chemical composition and physical properties of A179 steel pipe
The chemical composition of A179 steel pipe is mainly 10# steel, which belongs to low-carbon steel with good ductility and toughness. This steel pipe is usually used in equipment that requires high heat transfer efficiency. Because of its small wall thickness, it is particularly suitable for heat transfer equipment such as tubular heat exchangers and condensers.
Application field of A179 steel pipe
A179 steel pipe is mainly used to manufacture heat exchangers and condensers, which play a key role in industrial production and refrigeration systems. Due to its excellent heat transfer performance and corrosion resistance, A179 steel pipe is widely used in the petroleum, chemical, electric power and other industries.
What is A179 embedded fin tube?
A179 embedded fin tube is a special fin tube, which is mainly used in heat exchange equipment to improve heat exchange efficiency. A179 material usually refers to seamless tubes used in heat exchangers and condensers, while embedded fin tubes are directly processed on the surface of steel tubes to form a fin-like structure, thereby providing a larger heat dissipation area in a smaller space.

Notes:
- Base tube hardness ≤72 HRB (Rockwell B scale) for low-carbon steel variants.
- Custom specifications (e.g., alternative steel grades/non-ferrous alloys) negotiable with manufacturers.
- Fin dimensions (height/density) and materials (e.g., aluminum/copper fins) vary by thermal design requirements.
Embedded fin tubes primarily utilize seamless cold-drawn tubes compliant with ASTM A179/ASME SA179 standards for base construction.
A179 embedded fin tube structure and manufacturing process
The structural feature of A179 embedded fin tube is that multiple grooves are processed on the surface of the steel tube to form a fin-like structure. This design enables the heat dissipation area to be increased in a limited space, thereby improving the heat exchange efficiency. In terms of manufacturing process, embedded fin tubes require special processing on the surface of the steel tube, and the process is relatively complicated.
A179 embedded fin tube application scenarios and advantages
Due to its unique structure and manufacturing process, the A179 embedded fin tube is particularly suitable for use in space-constrained occasions.
Its advantage is that it can provide a large heat dissipation area in a small space, which is suitable for occasions that require efficient heat transfer. In addition, fin tubes are also widely used in industries such as industry, agriculture, and chemical industry, and have excellent heat dissipation and corrosion resistance.
