ASTM A106 Seamless Steel Pipe Specifications
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. Federal Steel Supply is a world leader in the supply of A106 / SA 106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/8″ to NPS 48″, with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification*. Pipe ordered under this specification shall be suitable for bending, for flanging, for welding, and for similar forming operations. A full range of A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.
