First, Definition and Application of SA210C High-Temperature Boiler Steel Pipe
Definition: SA-210C boiler steel pipe is a carbon-manganese steel small-diameter pipe specified in the ASME SA-210 standard. It is a pearlitic heat-resistant steel used for boilers and superheaters.
Application: Primarily used in the manufacture of boiler pressure components such as economizers, water walls, and low-temperature superheaters. It is suitable for operating temperatures below 500°C (some say below 450°C).
Second, 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%, and silicon ≥ 0.10%. These components give the SA-210C boiler steel pipe excellent mechanical properties and thermal strength. Physical and Mechanical Properties: SA-210C boiler steel pipes have a tensile strength of≥485 MPa, a yield strength of≥275 MPa, an elongation of≥30%, and a hardness of ≤89 HRB. These performance parameters ensure SA-210C boiler steel pipes maintain excellent strength and toughness in high-temperature and high-pressure environments.
Third, Production Process and Specifications of SA210C High-Temperature Boiler Steel Pipes
Production Process: The production process for SA-210C boiler steel pipes primarily includes hot rolling, cold drawing, and continuous rolling, with hot rolling being the most common method. These processes ensure SA-210C boiler steel pipes maintain precise dimensions and excellent surface quality.
Specifications: The outer diameter of SA-210C boiler steel pipes typically ranges from 57mm to 762mm (also known as 1mm to 80mm, 4mm to 80mm, 8mm to 50mm, or 1mm to 300mm). Wall thicknesses typically range from 3.0mm to 130mm (also known as 3.91mm, 9mm, 12mm, and 13.5mm). These specifications meet the manufacturing requirements of various boiler equipment.
Fourth, Application Cases and Advantages of SA210C High-Temperature Boiler Steel Pipes
Application Cases: SA-210C boiler steel pipes are widely used in large-scale domestic thermal power generation boilers.
Advantages: Compared with materials such as 20G, SA-210C boiler steel pipes have higher yield strength and excellent hot and cold workability. Using SA-210C boiler steel pipes can reduce wall thickness and material usage, thereby improving boiler heat transfer and conserving steel.
Fifth, Precautions and Maintenance of SA210C High-Temperature Boiler Steel Pipes
- Precautions: When using SA-210C boiler steel pipes, ensure that the operating temperature does not exceed the maximum allowable operating temperature to avoid material performance degradation or safety accidents.
- Maintenance: Regularly inspect and maintain SA-210C boiler steel pipes, including checking for defects such as cracks and corrosion, and performing necessary cleaning and maintenance to ensure long-term safe and reliable operation.
In summary, SA-210C boiler steel pipe (SA210C high-temperature boiler steel pipe) is a high-performance, high-quality seamless steel pipe for boilers with a wide range of applications and significant value. During use, various parameters and precautions must be strictly controlled to ensure safe and reliable operation.
