This post was last edited by llu85 on 2016-8-5 09:41. Technical discussant: llu85. Specialization: Pipeline stress. My area of expertise is the analysis of pipeline stress in petroleum refining and chemical processing plants. Online time per day/week: Monday to Friday, from 10 a.m. to 4 p.m. Work experience: Pipeline stress analysis work (Caesar was used frequently in this work; Autopipe was hardly ever used). ) I only like to discuss issues in order to enhance both parties’ understanding of certain aspects of stress. But I really don’t want to ask for information, and I don’t have much of it either. There is a lot of information on the forum; those who need it can use the search function. It is hoped to find answers through searches on Google or within forums, as well as by referring to guidelines, before asking a question.
Bro Lu, what’s the purpose of posting this? I didn’t understand? Should everyone introduce themselves, or shall I help answer questions online?
Take a look at this post and you’ll understand http://bbs.hcbbs.com/thread-980343-1-1.html
I have a question for all the marine industry professionals: how to choose an expansion joint correctly? How to simulate an expansion joint in Caesar? ? Thank you! ! ! !
Your question is too broad. There are eight or nine types of expansion joints, and each type comes in both a simple version and a complex version. This cannot be clarified through a forum discussion. Simulation is an issue; choosing the right type and parameters for the expansion joint is what’s most important.
If I can determine the type of expansion joint, do I just need to enter the corresponding stiffness values when modeling? ? ? Also, what does the effective diameter inside the expansion joint mean? What is the difference between winning and losing? ? ?
If the selection is done properly, simulation can be carried out using the correct stiffness and dimensions. The effective inner diameter is used to calculate the blind plate force. Expansion joints with simple modeling and no blind plate force do not require input, while those with complex modeling do.
I’m a beginner who doesn’t know how to perform these calculations. I hope you can explain your approach to solving the problems you encounter in your work, and share your experience to help beginners master stress analysis more quickly. Thank you very much!
Tang Yongjin’s \"Stress Analysis of Pressure Pipes\", as well as pipeline codes such as B31.3 and B31.1. After reading these books, learn *how to use the software and how to arrange the pipelines, etc. Design is something that requires gradual accumulation; as long as you put in effort, there will definitely be rewards.
Pipe pressure: -7 mbar, pipe diameter DN 900, length of the pipe approximately 15 meters, material: 304; it is installed at a height of around 4 meters above the ground. I’m not sure what thickness of pipe would be suitable 4mm？ 5mm？ 1mm might be enough for the calculation, thank you
This is a question related to the field of pipeline materials.
