STANDARD SPECIFICATION FOR SEAMLESS COLD-DRAWN LOW-CARBON STEEL HEAT-EXCHANGER AND CONDENSER TUBES


Document Abstract
This specification(Footnote 2) covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

This specification covers tubes â…› to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.

NOTE 1 - Tubing 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 â…› in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm].

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.

Footnote 2 - For ASME Boiler and Pressure Vessel Code applications see related Specification SA-179 in Section II of that Code.
