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.

ASTM Specification A106 covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending, flanging and similar forming operations. NPS 1-1/2 and under may be either hot finished or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface finish standards are outlined in the specification.

Process of ASTM A106 seamless steel pipes
The steel shall be killed steel, with the primary meltling process being open-hearth,basic-oxygen,or electric-furnace,possibly combined with separate degassing or refining. If secondary melting, using electroslag remelting or vacuum-arc remelting is subsequently employed, the heat shall be defined as all of the ingots remelted from a single primary heat.

Steel cast in ingots or strand cast is permissible. When steels of different grades are sequentially strand cast, identification of the resultant transition material is required. The producer shall remove the transition material by any established procedure that positively separates the grades.

Heat treatment of
Hot-finished pipe need not be heat treated.When hot finished pipe is heat treated, it shall be heat treated at a temperature of 1200°F(650℃) or higher.

Cold drawn pipe shall be heat treated after the final cold draw pass at a temperature of 1200°F(650℃) or higher.
