ASTM A106M is one of the standards set by the American Society for Testing and Materials (ASTM). It mainly specifies the mechanical performance requirements, chemical composition, shape, size and Allowable deviations, test methods, etc. This standard applies to mild steel pipes used in piping systems in areas such as heating, gas supply, oil and gas transmission.
The chemical composition of ASTM A106M seamless steel pipe mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), nickel (Ni), chromium (Cr), copper (Cu), Elements such as molybdenum (Mo) and vanadium (V). The specific chemical composition content is as follows:
The content of carbon (C) does not exceed 0.25%. The content of silicon (Si) does not exceed 0.10%. The content of manganese (Mn) is between 0.27~0.93%. The content of phosphorus (P) does not exceed 0.035%. Sulfur (S) content does not exceed 0.035%. The content of nickel (Ni) does not exceed 0.40%. The content of chromium (Cr) does not exceed 0.40%. The content of copper (Cu) does not exceed 0.40%. The content of molybdenum (Mo) does not exceed 0.15%. The content of vanadium (V) does not exceed 0.08%.
The production methods of ASTM A106M seamless steel pipe mainly include hot rolling, cold drawing and hot expansion. The choice of these production methods depends on the specification and material of the steel pipe and the required performance characteristics.
The characteristics of ASTM A106M seamless steel pipe are mainly reflected in the following aspects:
1. Excellent mechanical properties: It has high strength and hardness, can withstand harsh environmental conditions such as high pressure, high temperature and vipation, and shows excellent mechanical properties.
2. Good corrosion resistance: Because it contains a small amount of alloy elements, it shows good corrosion resistance in corrosive environments such as acid, alkali and salt, and is not easy to rust even in humid or acid-base environments.
3. Good processing performance: It has excellent plasticity and processability, can easily undergo hot and cold deformation, realize processing of various shapes and sizes, and is easy to install and maintain.
ASTM A106M seamless steel pipe has a wide range of applications, mainly including the following fields: Petroleum industry: used for the transportation of oil and natural gas. Its excellent high temperature resistance and high pressure resistance enable it to cope with harsh environmental conditions. Chemical industry: In the chemical industry, it is used for the transportation and storage of process fluids. Its corrosion resistance and high pressure resistance allow it to cope with the complex composition of chemical fluids and harsh working environments. Electric power industry: used for the transportation of high-temperature fluids such as steam and hot water. Its high temperature resistance ensures the stable operation of pipelines in high temperature environments. Machinery manufacturing industry: used in the manufacturing of various mechanical equipment, such as pumps, valves, compressors, etc. Its high strength and corrosion resistance make mechanical equipment more durable and reliable. Used in the boiler industry, such as water wall tubes in water walls, economizers, and reheater steam pipes. In addition, it also plays an important role in various industries such as shipbuilding, aviation, aerospace, energy, geology, construction and military industry.
