A106 Grade B Seamless Carbon Steel Pipe is a seamless carbon steel pipe produced according to the ASTM A106 standard set by the American Society for Testing and Materials (ASTM).
The standard divides seamless carbon steel pipe into three grades: A, B and C, of which grade B is the most widely used grade.
The chemical composition of A106 Grade B seamless carbon steel pipe is as follows:
Element | Maximum | Minimum |
---|---|---|
Carbon (C) | 0.30% | - |
Manganese (Mn) | 1.06% | 0.29% |
Phosphorus (P) | 0.035% | - |
Sulfur (S) | 0.035% | - |
Silicon (Si) | - | 0.10% |
Chromium (Cr) | 0.40% | - |
Copper (Cu) | 0.40% | - |
Molybdenum (Mo) | 0.15% | - |
Nickel (Ni) | 0.40% | - |
Vanadium (V) | 0.08% | - |
The mechanical properties of ASTM A106 Grade B Carbon Steel Seamless Pipes are as follows:
Property | Value |
---|---|
Tensile Strength (T.S) | ≥415 MPa |
Yield Strength (Y.S) | ≥240 MPa |
Elongation (EL) | ≥22% |
ASTM A106 Seamless Carbon Steel Pipes can be manufactured by cold drawing or hot working process:
Cold-drawn: high dimensional accuracy and smooth surface, suitable for applications requiring high dimensional accuracy and strength.
Hot working: the surface may have oxidized skin or other traces of hot working, suitable for applications requiring low dimensional accuracy but high plasticity of the material.
The dimensional range of A106 Grade B carbon steel seamless pipe is:
OD: NPS 1/8 - NPS 48 (DN 6 - DN 1200)
Wall thickness: in accordance with ASME B36.10.
A106 B grade carbon Seamless Steel Pipes are widely used in the following fields:
Oil and gas industry: used for extraction, transportation and storage of oil and gas.
Chemical industry: used for transportation of various chemical raw materials, intermediate products and finished products.
Electric power industry: used for steam piping and water supply piping in thermal power stations.
Construction industry: used in building water supply and drainage systems, heating piping systems, etc.
