Product Description
The GB 30813 standard pertains to welded austenitic stainless steel tubes and pipes specifically designed for use in nuclear power plants. These tubes and pipes play a critical role in ensuring the safe and efficient operation of nuclear power plants. This article will provide an overview of the material, specifications, chemical composition, mechanical properties, and applications of GB 30813 stainless steel tubes and pipes.
The GB 30813 standard specifies the use of austenitic stainless steel for the production of tubes and pipes. Austenitic stainless steel is known for its excellent corrosion resistance, high strength, and durability. These qualities are highly desirable in the harsh and demanding environments found in nuclear power plants. The use of austenitic stainless steel ensures the longevity and reliability of the tubes and pipes, contributing to the overall safety and efficiency of the nuclear power plant.
The GB 30813 standard provides detailed specifications for the production and quality control of austenitic stainless steel tubes and pipes. It covers various aspects, including dimensions, tolerances, surface conditions, and testing requirements. The specifications ensure that the tubes and pipes adhere to strict quality standards and meet the necessary criteria for their intended use in nuclear power plants.
The following table presents the chemical composition requirements specified in GB 30813 for the austenitic stainless steel used in the production of tubes and pipes for nuclear power plants:
| Element | Chemical Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.035 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.030 |
| Nickel (Ni) | 9.0 - 12.0 |
| Chromium (Cr) | 17.0 - 20.0 |
| Molybdenum (Mo) | ≤ 0.65 |
| Nitrogen (N) | ≤ 0.10 |
Note: These values are for reference only and should be verified with the updated GB 30813 standard.
The mechanical properties of the austenitic stainless steel tubes and pipes conforming to GB 30813 are as follows:
| Property | Minimum Value |
|---|---|
| Tensile Strength (MPa) | ≥ 520 |
| Yield Strength (MPa) | ≥ 205 |
| Elongation (%) | ≥ 35 |
| Hardness (HRB) | ≤ 90 |
| Impact Toughness (J/cm²) | ≥ 50 |
Note: These values are for reference only and should be verified with the updated GB 30813 standard.
GB 30813 welded Austenitic Stainless Steel Tubes and Pipes find their application in nuclear power plants for various purposes, including:
Coolant Circulation: These tubes and pipes are used to circulate coolant within the nuclear power plant to remove excess heat generated during the power generation process.
Steam Generation: Austenitic stainless steel tubes and pipes are utilized to generate steam in the nuclear power plant, which drives the turbines and generates electricity.
Containment Systems: These tubes and pipes are also employed in the construction of containment systems that ensure the safe confinement of radioactive materials within the power plant.
The high-quality and durable nature of GB 30813 welded Austenitic Stainless Steel Tubes and Pipes make them the ideal choice for critical applications in nuclear power plants.
