SA 179 Tubes / ASTM A179 Tubing for Heat Exchanger

ASTM A179 (ASME SA179) Seamless Carbon Cold Drawn Steel Tubes

Applications: For Heat exchanger, condensers tubes, heat transfer thermal equipment

OD Dimensions: Up to 3 inch

ASME SA179 or ASTM A179 tubes is a type of seamless pipe material in carbon, with small wall thickness and diameters. (Most is required below 3 inch.)

What is ASME SA 179 (ASTM A179) Standard Specification

ASTM A179 (SA 179) standard specification covers seamless cold drawn low carbon steel pipe, for tubular heat exchanger, condensers and other similar heat transfer equipment.

The ASTM A179 tube covers the OD from 1/8” to 3”, which is 3.2m m to 76.2 mm. Other diameters and thickness smaller than the specified sizes also applicable to this standard, but mechanical properties is not applicable for the size smaller than 1/8” and 3.2 mm, or thickness smaller than 0.015 inch 0.4 mm.

Referred standards for manufacturing SA 179 tubes

Related ASTM standards is ASTM A450/A 450M The standard specification for the general requirements for carbon steel, ferritic alloy, austenitic alloy steel tubes.
