ASTM A179 Seamless Carbon Steel Tubes

ASTM A179 or ASME SA179 tubes is a type of seamless pipe material in carbon, with small wall thickness and diameters. (Most is required below 3 inch.)
It covers seamless cold drawn low carbon steel pipe, for tubular heat exchanger, condensers and other similar heat transfer equipment.


ASTM A179 alloy steel piep usually used in high temperature boiler tubes.

Production Process Introduction

Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube’s physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.

CDS seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.
