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.
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.

Buildings, infrastructure, tools, ships, automobiles, machines and appliances are all made from steel. Steel is frequently used because it is durable and safe. Building materials underground may be susceptible to rotting and pests. Since steel is non-combustible and makes it harder for fire to spread, it is good to use when building homes. ASTM A106 Carbon steel pipe is highly resistant to shock and vibration. A106 GR. B Carbon Steel Seamless Pipes is Environmentally Friendly as well Cost-Effective.
Carbon steel pipe – Examples of use
Bridges, Flood control, Harbors and airports, Building construction, Petroleum and natural gas, Wind power generation, Solar power and solar heat power generation, Geothermal power generation, Batteries and power devices etc.
