ASTM SA/A106 Seamless Steel Pipe Specifications
ASTM SA/A106 pipe (also covered in ASME specifications as SA/A106) 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 / SA106 pipe and stocks a full range of grades B/C in a size rage of NPS 1/2″ to NPS 36″, 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 SA/A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.
