A179 pipe

This specification covers tubes 1/8 to 3 in. [3.2 to 76.2 mm],

inclusive,in outside diameter. Note 1Tubing smaller in outside

diameter and havinga thinner wall than indicated in this

specification is available. Mechanical property requirements

A179 pipe

do not apply to tubing smaller than 1/8 in. [3.2 mm] in

outside diameter or with a wall thickness under 0.015 in. [0.4 mm].

This specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat

transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn.

Heat and product analysis shall be performed wherein steel materials shall conform to

required chemical compositions of carbon, manganese, phosphorus, and sulfur.

The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.
