Construction

ASTM A 106

ASTM A106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

ASTM A106/ASME SA106 is the standard specification for seamless carbon steel pipe applied for high temperature services. It includes three grades A, B and C, and common use grade is A106 Grade B. It used in different industries not only for pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.
ASTM A106 Grade B pipe is equivalent to ASTM A53 Grade B and API 5L B on chemical position and mechanical properties, in general use carbon steel and yield strength minimum 240 MPa, tensile strength 415 Mpa.
