The standard specification for seamless carbon steel pipe used in high-temperature services is ASTM A106/ASME SA106. It comes in three different grades—A, B, and C—with A106 Grade B being the most widely used. It is utilised in a variety of industries for boilers, building, and structural needs in addition to pipeline systems for the transmission of water, mineral slurry, oil, and gas.
According to chemical composition and mechanical characteristics, ASTM A106 GR. B CS Pipes are comparable to ASTM A53 Grade B and API 5L Grade B. It is made of carbon steel and has a minimum yield strength of 240 MPa and maximum tensile strength of 415 MPa for general use.
In terms of composition, the alloy’s carbon content in the A106 carbon steel pipe is 0.30 per cent. Carbon is not the only alloying element included in SA 106 Gr B Sch 40 pipes; there is also 1.20 % manganese, 0.05 % phosphorus, and 0.05 % sulphur. The ASTM A106 Gr. B Material also contains the following minerals: 0.15% molybdenum, 0.08% vanadium, 0.40% chromium, 0.40% copper, 0.40% niobium, and 0.40% vanadium. In the ASTM A106 GR. B CS Pipes overall composition, these trace elements shouldn’t make up more than 1%.
In industries where it is necessary to carry gases and fluids from the site to the refineries, ASTM A106 GR. B CS Pipes are used. These locations could be either on- or offshore. The A106 Gr B Erw Pipe is preferred for use in industries like boilers, power plants, oil and natural gas pipelines, petroleum refineries, and petrochemical facilities. These pipes, which are graded A106 gr. B, are strong and can endure high pressure and temperature when carrying fluids or gases. A106 Gr B Welded Pipe is therefore preferred by numerous businesses.
