Does it include -20 degrees Celsius, or are there other standard definitions? Which clause of that standard, thank you! (Pressure vessels have a clear definition)
For low-temperature pipelines made of carbon steel and low-alloy steel, the definition of temperature may vary depending on different standards and application scenarios. Generally speaking, temperature ranges below minus 20 degrees Celsius can be considered low-temperature conditions. But to answer your question accurately, we need to consult the specific relevant standards and industry guidelines. Regarding the relevant definitions of pressure vessels, in accordance with the \"Regulations on Safety Supervision of Pressure Vessels\" (TSG R0004-2009), Appendix A classifies the steels used in pressure vessels and specifies the corresponding temperature ranges. Among them, carbon steel containers can be used in temperature ranges from -20°C to 400°C, while low-alloy steel containers can be used in temperature ranges from -40°C to 450°C. At the same time, the \"Steel Pressure Vessels\" standard (GB150.1-2011) also specifies the temperature limits for the use of relevant steel materials. In general, the definition of low-temperature pipelines for carbon steel and low-alloy steel can refer to the standards mentioned above, with judgments made based on specific application scenarios and industry requirements. If you have further inquiry needs, please provide more contextual information so that we can help you find more detailed information. .
