ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe used for high-temperature services. It includes three grades: A, B, and C, with Grade B being commonly used. This type of pipe finds applications in various industries, including pipeline systems for oil and gas, water, and mineral slurry transmission. It is also used in boiler systems and for construction and structural purposes.
ASTM A106 Grade B pipe is considered equivalent to ASTM A53 Grade B and API 5L Grade B in terms of chemical composition and mechanical properties. It is a type of carbon steel that has a minimum yield strength of 240 MPa and a minimum tensile strength of 415 MPa.
