Seamless steel pipe (SMLS pipe) is a widely used material with no welds, offering good pressure resistance and corrosion resistance. It is extensively utilized in construction, mechanical processing, electrical, petrochemical, and other industries. This type of steel pipe is ideal for transporting high-temperature fluids such as water, oil, and gas due to its excellent mechanical properties and chemical composition.
Execution Standards:
The A106 seamless steel pipe adheres to American standards ASTM A106-ASME SA106, with mechanical performance indicators including tensile strength and yield strength, ensuring reliability in high-temperature fluid transportation. The chemical composition of A106 seamless steel pipe is strictly controlled, including elements like carbon, silicon, manganese, phosphorus, and sulfur, which ensure corrosion resistance and strength.
Classification of ASTM A106 Seamless Steel Pipe:
A106A: Primarily composed of carbon (C) and silicon (Si), with a tensile strength of 330 MPa.
A106B: Composed of carbon (C), manganese (Mn), and silicon (Si), with a tensile strength of 415 MPa.
A106C: Composed of carbon (C), manganese (Mn), and silicon (Si), with a tensile strength of 485 MPa.
Each grade has specific characteristics and applications, determined by the use environment and requirements.
