ASTM A179 Seamless Heat Exchanger Tube | SA179 Carbon Steel Boiler & Condenser Tube
Product Overview
ASTM A179 / ASME SA179 seamless heat exchanger tubes are low carbon steel cold drawn tubes designed for heat transfer equipment such as heat exchangers, condensers, boilers, and similar thermal processing systems.
Manufactured through seamless cold drawing technology, A179 tubes provide stable dimensional consistency, uniform wall thickness, and reliable surface quality for industrial heat transfer applications. Compared with welded tubes, seamless construction helps reduce welding-related leakage risks and improves reliability under continuous thermal cycling conditions.
