Adding diagonal blind plates at the flanges of pressure pipes at the GC3 level (by cutting and welding to shorten the length of the pipe sections) does this constitute a modification to the pressure pipes?
Thread Content
Hello everyone, I have a question: Is adding an L-shaped blind plate at the flange of a pressure pipeline at the GC3 level – by cutting and welding to shorten the length of the pipe section – considered a modification to the pressure pipeline? Is it necessary to file a notification for such an action?
According to the latest regulations, there are no GC3 pressure pipelines anymore
Ask for the opinions of the construction party or the owner. In a way, it’s a bit of an overreaction.

Check whether, in accordance with the latest pipeline specifications, it has been classified as a GC2 pipeline; if it is indeed classified as GC2, then this should be communicated, and it is advisable to consult the local market supervision authorities.
