ASME SA179 Seamless Boiler Tube

ASTM A179 Tube specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.
Product introduction

ASME SA179 Seamless Boiler Tube Specification
ASTM A179 Tube specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers,
condensers, and similar heat transfer apparatus. SA 179 tube 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.
