ASTM A106 steel, fully designated as ASTM A106, is a seamless carbon steel pipe material under American standards, specifically designed for high-temperature and high-pressure applications. Renowned for its exceptional high-temperature resistance, high-pressure performance, and good corrosion resistance, it is widely used in high-temperature and high-pressure environments such as oil refining, chemical processing, power generation, and boiler systems.
ASTM A106 pipes are categorized into three types:
Type A: Drawn to reduce machinability or hot-finished.
Type B: Annealed and tempered.
Type C: Cold-worked.
Specification
Size:ranging from 1/2 to 28 inches
