What is ASTM A179 specification?
The specifications of ASTM A179 steel pipe mainly include the thinnest wall seamless steel pipe with an outer diameter range of 3.2 mm to 76.2 mm, which is suitable for tube heat exchangers, condensers and similar heat transfer devices. This kind of steel pipe is usually made of low carbon steel, and its chemical composition and mechanical properties should meet specific standards to ensure its safety and reliability in high temperature and high pressure environments.
