SA-210C boiler steel pipe, also known as SA210C high-temperature boiler steel pipe, is a seamless steel pipe for boilers designed for high-temperature and high-pressure environments. The following is a detailed introduction to it:
First, the definition and use of SA210C high-temperature boiler steel pipe
Definition: SA-210C boiler steel pipe is a steel grade in the ASME SA-210 standard. It belongs to small-diameter carbon-manganese steel pipes for boilers and superheaters, pearlite-type heat-resistant steel.
Use: Mainly used to manufacture economizers, water-cooled walls, low-temperature superheaters, and other components in boiler pressure components, suitable for operating temperatures below 500°C (some say below 450°C).
Second, the chemical composition and physical and mechanical properties of SA210C high-temperature boiler steel pipe
- Chemical composition: The main chemical composition of SA-210C boiler steel pipe includes carbon ≤ 0.35%, manganese 0.29~1.06%, phosphorus ≤ 0.035%, sulfur ≤ 0.035%, silicon ≥ 0.10%. These components make SA-210C boiler steel pipe have excellent mechanical properties and thermal strength.
- Physical and mechanical properties: The tensile strength of SA-210C boiler steel pipe is ≥ 485MPa, the yield strength is ≥ 275MPa, the elongation is ≥ 30%, and the hardness is ≤ 89HRB. These performance parameters ensure that SA-210C boiler steel pipe has good strength and toughness under high temperature and high pressure environments.
Third, the production process and specifications of SA210C high-temperature boiler steel pipe
- Production process: The production process of SA-210C boiler steel pipe mainly includes hot rolling, cold drawing, continuous rolling, etc., among which hot rolling is a commonly used production method. These processes ensure that SA-210C boiler steel pipes have precise dimensions and good surface quality.
- Specifications: The outer diameter range of SA-210C boiler steel pipes is usually 57mm762mm (there are also different specifications such as 1mm80mm, 4mm80mm, 8mm50mm, 1mm300mm, etc.), and the wall thickness range is usually 3.0mm130mm (there are also specific specifications such as 3.91mm, 9mm, 12mm, 13.5mm, etc.). These specifications meet the manufacturing needs of different boiler equipment.
Fourth, the application cases and advantages of SA210C high-temperature boiler steel pipes
- Application cases: SA-210C boiler steel pipes are widely used in large domestic thermal power generation boilers.
- Advantages: Compared with materials such as 20G, SA-210C boiler steel pipes have higher yield strength and good cold and hot processing performance. Using SA-210C boiler steel pipes can reduce wall thickness and reduce material consumption, thereby improving the heat transfer of boilers and saving steel.
Fifth, precautions and maintenance of SA210C high-temperature boiler steel pipes
- Precautions: When using SA-210C boiler steel pipes, ensure that the working environment temperature does not exceed the maximum allowable use temperature to avoid material performance degradation or safety accidents.
- Maintenance: Regularly inspect and maintain SA-210C boiler steel pipes, including checking whether the pipes have cracks, corrosion, and other defects, and performing necessary cleaning and maintenance work to ensure long-term safe and reliable operation.
In summary, SA210C high-temperature boiler steel pipes are high-performance, high-quality seamless steel pipes for boilers, which have a wide range of applications and important use value. During use, various parameters and precautions must be strictly controlled to ensure safe and reliable operation.
