Product Introduction

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.
