ASTM A106 seamless steel pipe

ASTM A106 seamless steel pipe is a type of American standard seamless steel pipe designed for use in high-temperature environments. It comes in two grades: ASTM A106 Grade A and ASTM A106 Grade B, equivalent to China's #10 and #20 materials, respectively. As part of the ordinary carbon steel series, ASTM A106 seamless steel pipe is manufactured using two different processes: cold drawing and hot rolling. These processes impact the pipe's accuracy, surface quality, minimum size, and mechanical properties.

The nominal size range for these pipes is from NPS 1/8 to NPS 48, with nominal wall thickness prescribed by ANSI B36.1. Other dimensions can be supplied as long as they meet this standard. According to ASTM A106, the raw materials used must be suitable for bending, curling, and similar forming operations.
