Product Overview – ASTM A179 Pipes & Tubes
ASTM A179 pipes and tubes are manufactured using low carbon steel, specifically designed for heat transfer applications.
These seamless tubes are produced through cold drawing processes, ensuring high dimensional accuracy, smooth internal surface, and consistent wall thickness— all critical for efficient heat exchange.
Unlike general-purpose pipes, ASTM A179 tubes are optimized for thermal conductivity and pressure handling in heat exchangers and condensers.
They are widely used in boilers, power plants, chemical industries, and process equipment.
Their reliability and performance make them a preferred choice for thermal system manufacturers and EPC contractors.
