A106 Pipe is the black carbon steel pipe, A106 Gr B Sch 40, A106 Gr B Erw Pipe and ASTM A106 Seamless Pipe for high-temperature and high-pressure service. ASTM/ASME A-106/SA-106 grade seamless pipes are one of our most widely used grade of carbon steel and are readily available ex-stock for all standard thicknesses up to SCH160. These A106 Seamless Pipes, SA106 Pipe, ASTM A106 Grade B Line pipe are available in three grades A, B, and C of varying strength. NPS 1-1/2 and under may be either A106 grade b hot finished or A106 grade b cold drawn. NPS 2 and larger shall be A106 grade b hot finished unless otherwise specified. Surface finish standards are outlined in the specification. SA106 Material, ASTM A106 Grades A and ASTM A106 B are obtainable in most sizes and schedule numbers, SA106 Grade B permits higher carbon and manganese contents than Grade A. The A106 Grade B Pipe, ASTM A106 Grade B Schedule 40 Pipe and A106 Black Pipe supplied by ASTM Seamless Pipes has a maximum carbon content of 0.23%.
Its known for superior
grade of pipe.

Hydrostatic Testing |
Inspection test pressures produce
a stress in the pipe wall equal to 60% or specified minimum yield strength
(SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for
NPS 3 and under and 2800 psi for the larger sizes. Pressure is
maintained for not less than 5 seconds. |
