ASTM A179/A179M,  ASME SA179/SA179M is the standard applicable to Seamless cold drawn low carbon steel heat exchanger and condenser tubes.

ASTM A179 covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.

ASTM A179 is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

General scope of ASTM A179

1.ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.
2.ASTM A179 covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. Note 1Tubing smaller in outside diameter and having a thinner wall than indicated in this specification is available. Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm].
3.The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the ‘M’ designation of this specification is specified in the order.

Note:

• Mill test certificates will be issued according to EN10204.3
• All tubes shall be supplied as per applicable ASTM Specification.
• The tubes Shall be Seamless and the testing shall be as per A 450 / A450M.

Application: apply to the heat exchangers, condensers and heat transfer equipment and similar pipe.

Packing:

• Packed in wooden crates, wrapped in plastic, and suitably protected for sea-worthly delivery or as requested.
• Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles.
