ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures.
ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 pipe) covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations. ASTM/ ASME A106/SA106 Seamless ASTM A106 Grade B Pipe is heat resistant and ideal for industrial applications with elevated temperatures. ASTM/ASME A106/SA106 seamless carbon steel pipe is used in industrial applications involving high heat, including process piping, boiling plants, compression stations and refineries. The additional silicon boosts this product’s performance in high-temperature environments, such as steam lines and processing applications.

Process
Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.
Steel cast in ingots or strand cast is permissible.
Hot-finished pipe need not be heat treated.
Cold-drawn pipe shall be heat treated after the final cold draw pass.
