ASTM A106 Seamless Carbon Steel Pipe – Definition & Use Cases

ASTM A106 (Grades A/B/C) covers seamless carbon steel pipe for high-temperature service, widely used in refineries, chemical plants, power stations, boilers and heat-exchangers. Pipes can be hot-finished or cold-drawn, with optional normalizing or stress-relief per service requirements.
