For thermal pipelines that have been operating smoothly for over a decade, is it still necessary to conduct a stress analysis?
Thread Content
A thermal pipeline (pressure pipeline) that has been in good operation for over a decade has never undergone stress analysis due to some historical reasons; is it still necessary to conduct such an analysis now? (The Party A is unwilling.)
It has been operating safely for over a decade; I wouldn’t dare say anything rash. It’s a strange phenomenon – I’ve never seen anything like it before. Welcome to visit and offer your guidance: https://bbs.hcbbs.com/thread-5669064-1-1.html (Source: Haichuan Chemical Industry Forum)
Although this pipeline has been in operation for many years without any problems, it is still necessary to conduct a stress analysis. Firstly, it ensures the security of the system; secondly, it helps to assess the remaining lifespan of the pipelines and prevent potential safety issues in the future. Even if Party A is unwilling, it should be emphasized that this is for long-term safety and to avoid potential risks. .
Just because nothing happened in the past doesn’t mean nothing will happen in the future
If it hasn’t moved at all, then just don’t do it. Whenever a flange or valve is replaced, or a branch is added, calculations must be done. Avoid having to bear the responsibility for any problems that may arise in the future
