What is the inspection procedure after replacing a pressure pipeline that has not been in use and has passed the inspection?

It is a newly established project; the pipeline installation has been completed, and the pressure pipelines have passed the inspection requirements. All other conditions for starting up the system are also basically met. However, the system has not yet been brought online. For various reasons, it is now desired to replace these pressure pipelines – that is, to remove the already installed and inspected pipelines and purchase serta install new ones. Do these pipes need to be submitted for inspection following the “renovation” procedure? Or should we follow other procedures?

Based on the modifications, produce a new set of drawings
There’s no need for that; after reinstalling, it will be exactly the same as before, with no difference at all
Let’s go through the process again; produce another set of drawings. I’ve also learned *
It doesn’t matter whether there is a difference or not; what’s important is that you made changes to the pipes that had already been approved. Such changes require design drawings, and even if those drawings are identical to the original ones, they are still necessary – otherwise you won’t be able to submit an application for inspection.
I don’t think it’s about checking whether there have been changes to the structure, to the components under stress, or to the stress distribution; if none of these have changed, it can’t be considered a modification – it should rather be called repair
The construction blueprint has not changed, so there are no such alterations; it’s simply a matter of repurchasing the materials and then proceeding with construction. The procedures for renovation and repair are completely different; it’s confusing: Q
