What is the approach to determining the operating pressure and operating temperature, as well as the design pressure and design temperature, when creating a pipeline characteristic table?
Thread Content
I’m very afraid of creating pipeline characteristic tables, because I’m not always clear about the operating pressure, temperature, and design pressure, temperature for a particular pipeline in such tables. I really want to know how experts think about determining these values. Thank you!
The operating temperature and operating pressure are set to be 1.1–1.15 times higher than the design temperature and design pressure, depending on the actual operating conditions of the device.
This issue is too complex – it’s like asking a tiger to eat the sky! I’ll go back and check the design manuals and specifications before giving you an answer. However, there is one question: are the design pressure and design temperature of the pipes in a unit determined uniformly by the person in charge of the project?
The operating temperature and operating pressure can be determined based on the properties of the raw materials and the processing methods used. The design pressure, on the other hand, needs to be determined considering factors such as internal and external pressures; it is advisable to consult relevant standards and books for more information.
I’ve encountered the same problem as well; I hope some experts can provide additional information
I agree with LS; the operating temperature and pressure are determined by the production process, taking into account various factors such as conversion rate, product yield, reaction rate, and properties of the materials. The design pressure and temperature can be determined with reference to the standard \"Determination of Design Pressure and Design Temperature for Equipment and Pipeline Systems\", HG/T 20570.1–95. . . .
I also need to learn how to create pipeline property tables. Yes, I’m not sure how to determine the operating pressure and operating temperature for pipelines. I’m asking experts for help – could you provide a more detailed example?
The design pressure and temperature are higher than the maximum operating pressure and temperature; under normal conditions, the maximum operating pressure and temperature are higher than those specified on the nameplate
When I carry out design work, the operating temperature and pressure I use are the maximum values that may occur during production, while the design temperature and pressure are 1.1 times those operating values.
