How to design the long-distance transmission of superheated steam?
Thread Content
How should the design of a high-temperature and high-pressure pipeline be approached, which is used to transport superheated steam at 270°C and 1.0 MPa to a destination where the pressure is greater than 0.6 MPa and the temperature is above 185°C, over a length of more than 3 km? Could everyone please help recommend what standards should be used for design and which manuals can be referred to? I have no prior experience with this type of pipeline design; thank you!
This pressure isn’t very high. I’m not sure how much you know about steam pipelines; if you haven’t studied heating systems, you’ll likely need to learn from scratch. There are many things to keep in mind: resistance, compensation, material selection, and supports
This mainly relates to the calculation of pipeline stresses, that is, things like thermal compensation mentioned above; ordinary carbon steel can be used for the materials, and the rest is not a problem.
Thank you all. Is there any software for calculating superheated steam? If there are any, please help me introduce them!
There’s a lot of information on the forum regarding diameter calculation, compensator design, and insulation thickness. If you search through previous posts, you’ll be able to learn a lot. I’m afraid that if I try to upload that information to you, it will likely get reported as duplicate content. . . .

You may refer to the \"Code for Design of Boiler Steam and Water Pipelines\"
For the design of steam pipelines using such parameters, one can refer to the \"Power Pipeline Design Manual\"; it is also possible to use Excel to develop the software, or employ tools such as AutoPipe, CaesarII, and Youyi AutoPSA for these calculations. It’s not hard to calculate. However, this applies only to pipes laid overhead or in trenches; for pipes buried directly in the ground, the calculation using AUtoPSA is incorrect. It is said that it can be considered part of the improved version of AUtopipe; I have not used the direct burial version of CaesarII.
I’ve never heard of pipes under such temperature and pressure being buried directly underground in China
What was said on the second floor is correct; there’s not much of a problem with the equipment itself. The key lies in compensation and stress calculation. Since the delivery location is far away, the losses will be significant
The \"Heating and Ventilation Design Manual\" can be used as a reference
