Seamless Steel Pipe-ASME106 is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gasses that exhibit higher temperatures and pressure levels.Seamless Steel Pipe-ASME106 also known as ASME SA106 pipe.
Process | Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possible 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. |
