Regarding the service life of pipelines
Thread Content
There is a pipeline that is 59 years old, with a pressure of around 1 MPa. Now a cross-connected pipe is to be added; will the internal structure of the pipeline’s steel material and the wear on its wall thickness meet the requirements for construction, or could there be any risks? Please, an expert, give me an answer!
Have the wall thickness inspected by the safety technology supervision department, which will then issue a report
If it can be replaced, then replace it. It’s been decades since those pipelines were installed; your company surely doesn’t lack that amount of money, unless it’s special materials involved.
Our pipes from these 30 years need to be replaced. . . You haven’t been safe at all all these years. Change it
With that amount of time, manpower, and resources, it’s more cost-effective to replace it
59 years of pipelines – it’s really not easy!
A pressure of 1.0 MPa is not very high; although some analysis and judgment can be made based on the properties of the medium, it is considered a pressure pipeline according to regulations, and there are specific requirements. It cannot be adjusted at will, nor can changes be made arbitrarily – it is necessary to follow the regulations!
It’s been almost 60 years since 1959. . . . It needs to be replaced. . .
Thickness measurement and spectroscopy analysis – it seems that materials of the same type are hard to find these days. It’s better to choose replacement; anyway, steel is very cheap these days.
I’ve never seen a pipeline that has been in use for such a long time; as a precaution, it’s best to replace it with a new one. Don’t waste time on any calculations; it’s already been tested
