During the renovation of the GC2 pressure pipeline, can the valve flanges currently in use on the original pipeline still be utilized? Valves and flanges with certificates of conformity are available.

May I ask, during the renovation of the GC2 pressure pipeline, can the valve flanges currently in use on the original pipeline still be utilized? Are the valves and flanges equipped with certificates of conformity?
If the quality is fine, of course it can be used
Are the pipes still at GC2 grade after the renovation? If it meets the pipeline usage standards, the required pressure can be maintained with no leaks, and the valves and flanges of the original pipeline can be continued to be used
Determine whether the flange pound rating changes based on the design temperature and pressure; if the medium changes, assess whether the type of flange sealing surface meets the requirements according to the properties of the medium and relevant standards.
As long as the pipeline properties remain unchanged and the valve flanges are of good quality, it can definitely be used.
It can be used, but it is necessary to check the degree of corrosion; if it is satisfactory, there is no need to replace it, as there is no leakage or anything similar
First, determine whether the valves and flanges are usable, then check if the ones that were originally used can be applied to GC2-class pipelines; if not, they need to be replaced.
Those who are qualified should be able to do it!
If it’s not damaged and can meet the requirements as well as the standards for renovation, then it can be continued to be used. Replacing it with a new one is too expensive
