ASTM A106 Seamless Pressure Pipe
ASTM A106 Seamless Pressure Pipe (also known as ASME SA106) is a standard specification for seamless carbon steel pipes for high-temperature service. It is widely used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where piping must transport fluids and gases at higher temperatures and pressure levels. Gnee Steel offers Grades B and C in various sizes from NPS 1/8 to NPS 30 and schedules ranging from 10 to 160.
