Product Description

Carbon Steel SA179 Tubes are used widely due to its excellent tensile strength and yield strength. The properties of the SA179 grade is highly unmatched, some of them are good corrosion resistance, oxidation resistance, pitting resistance, resistance to acid, crevice corrosion resistance and excellent strength. ASTM A179 / ASME SA179 Seamless ColdDrawn Heat Exchanger Tubes offer excellent performance, durability, and heat transfer efficiency in industries such as petrochemical, power generation, and chemical processing. Their reliable, seamless construction ensures long-term functionality in demanding industrial applications. ASTM A179 / ASME SA179 is the specification for seamless colddrawn lowcarbon steel tubes used in heat exchangers, condensers, and similar systems that require high heat transfer efficiency. These tubes are extensively used in industries such as petrochemical, power generation, and oil and gas.

Longitudinal finned tubes are used to give a great performance in any heat transfer application, especially in petrochemical area. They are the heart of heat exchangers that use their effective characteristics. The finned tube are particularly efficient as the channels are welded on the external surface of the tube by means of resistance weld technique. Every channel is the result of a fin strip shaped into a Uform, such that each leg of the U will form a fin. The number of fins will be always a multiple of four with a maximum number depending on the outside diameter of the tube and on the thermodynamic calculations promoted for a specific job. This resistance weld gives the channels a very high adhesion to the external surface of the tubes. This characteristic grants a great heat transfer efficiency, so that thermodynamic calculations can also design heat exchangers equipments at the best way.
