ASME SA213 is the standard of the American ASME (The American Society of Mechanical Engineers, that is, the American Machinery Engineer Association). This standard is mainly suitable for equipment and components working in high temperature and high -pressure environments, such as boilers, furnaces, and heat exchangers. The SA213 standard defines the requirements of different materials, size and strength levels to ensure the quality and reliability of the product. It involves the material and manufacturing process of the steel pipe, and the material of the steel pipe must meet the relevant chemical composition and mechanical performance requirements.
There are a variety of different material pands under the ASME SA213 standard, and the chemical composition requirements of each material pand number are different. Here are some common ASME SA213 materials and their chemical composition requirements: SA213 T5: carbon content does not exceed 0.15%, manganese content is between 0.30 ~ 0.60%, the content of phosphorus and sulfur does not exceed 0.025%, and the silicon content does not exceed more than exceed 0.50%, chromium content between 4.0 and 6.0%, and molybdenum content between 0.45 and 0.65%. SA213 T12: The carbon content is about 0.15%, the manganese content is between 0.30 ~ 0.61%, the chromium content is between 0.80 and 1.25%, and the molybdenum content is between 0.44 and 0.65%.
The ASME SA213 standard mainly specifies the manufacturing of seamless medium -carbon alloy steel boilers and furnaces, so its production method mainly involves the manufacturing process of seamless steel pipes. Material preparation, perforation, heat treatment, cold processing, inspection and testing, marking and packaging.
The characteristics of the ASME SA213 standard are mainly reflected in the following aspects:
1. Strict material requirements: there are strict regulations for the chemical composition and mechanical properties of the material to ensure that the steel pipe has excellent performance in high temperature and high pressure environment.
2. Squity of the manufacturing process: Requires fine control of each process to ensure the quality and reliability of the steel pipe.
3. Excellent performance: High -strength, highly resistant corrosion, and good welding performance. They make them perform well in various complex environments, especially in the application of high -temperature and high -pressure boilers and furnaces.
4. Strict inspection and test requirements: Seamless steel pipes are required to perform strict chemical analysis, stretch tests, impact tests, hardness tests, heat treatment tests, and non -destructive testing to ensure the quality and safety of the product.
The seamless steel pipes under the ASME SA213 standard are mainly used for boiler and furnace hubs, especially equipment and components working in high temperature and high -pressure environments. Specifically, its application scope includes: boiler heating surface tube: heating surface tube used for various boilers, such as low -medium pressure boilers and high -voltage boilers. Provincial coal -saving, overheated and heating device; petrochemical industry pipes: used for the petrochemical industry, used to transport various corrosive media and high -temperature and high -pressure fluids to ensure the safe and stable operation of the petrochemical production line.
