ASTM A179 Boiler Tubes Manufacturer & Supplier

ASTM A179 boiler tubes are seamless cold-drawn low-carbon steel tubes designed for heat exchangers, condensers, and similar heat transfer equipment. The standard, also designated ASME SA-179 and UNS K01200, covers tubes manufactured by cold drawing from low-carbon steel with a carbon content of 0.06 to 0.18% and manganese at 0.27 to 0.63%. Phosphorus and sulphur are each limited to 0.035% maximum.

These tubes offer a minimum tensile strength of 325 MPa (47 ksi), a minimum yield strength of 180 MPa (26 ksi), and a minimum elongation of 35%. Cold drawing produces a smooth surface finish and tight dimensional tolerances, both critical for efficient heat transfer.

ASTM A179 Boiler Tube Applications

ASTM A179 heat exchanger tubes serve 3 primary industrial sectors.

Power Generation and Boiler Systems

A179 tubes line fire-tube and water-tube boilers in low-pressure power generation applications. Coal-fired and gas-fired plants use these tubes in economisers and feedwater heaters.

Petrochemical and Refinery Heat Exchangers

Refineries use ASTM A179 seamless tubes in shell-and-tube heat exchangers to cool process streams and maintain controlled operating temperatures.

HVAC and Condenser Systems

Many central chillers and industrial HVAC systems use ASTM A179 seamless condenser tubes for effective cooling and heat removal.

ASTM A179 vs ASTM A192 vs ASTM A210 Boiler Tubes

ASTM A179, A192, and A210 seamless tubes are used in heat exchangers and boilers. They are chosen based on the needed pressure, temperature, and strength.

ASTM Standard	Tube Type / Application	Key Features
ASTM A179	Cold-drawn seamless tubes	For heat exchangers and condensers
