To ensure the tubes meet the required standards, they are subjected to several tests like the Product Analysis, Hardness, Mechanical, Flattening, Flaring, Hydrostatic, or NDT tests, based on the client’s test requirements. The tubes must also conform to the applicable provisions of the current edition of Specification A 450/A 450M.
The ASTM A179 Tubes come in different sizes and varying wall thicknesses, and U-bending tubes can also be offered. Additionally, the tubes are subject to various test requirements, including ASTM A179 Tubes (ASME SA179 Tubes) Chemical Compositions, Mechanical Properties, Wall Thickness Tolerance, Outside Diameter Tolerance, Cut Length Tolerance, and Hydrostatic Test Pressures, to ensure quality.

Applications

The applications include tubular heat exchangers, condensers, and similar heat transfer apparatuses.

Typical Size

It is important to note that the ASTM A179/ASME SA179 is a standard that covers tubes ranging from 1/8 to 3 in. [3.2 to 76.2 mm] as typical size, inclusive, in outside diameter. Mechanical property requirements do not apply to tubing smaller than 1/8 in, [3.2 mm] in outer diameter or with a wall thickness under 0.015 inches [0.4 mm].

Scope of ASTM A179 Tubes

1. ASTM A179 Tubes (ASME SA179 Tubes) cover minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.
2. ASTM A179 Tubes (ASME SA179 Tubes) cover tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. Tubing smaller in outer 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 inches [0.4 mm].
3. The values stated in inch-pound, or SI units, are 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 this specification’s “M” designation is specified in the order.

Note

• The tubes are typically used in heat exchangers, condensers, heat transfer equipment, and similar pipe applications.

• Mill test certificates are issued according to EN10204.3, and the tubes shall be seamless with testing conducted as per A 450 / A450M.

• The application includes heat exchangers, condensers, heat transfer equipment, and similar pipe.

Packing of ASTM A179 Tubes

To protect the tubes during transportation, they are packed in wooden boxes or bundles with plastic paper and suitably protected for sea-worthy delivery. The product marking includes ASTM A179 or ASME SA179, size, heat no., lot number, and Manufacture name or logo.
