Weld flaw detection ratio

I would like to ask everyone: A pipeline contains butt welds and socket welds. 1. What is the inspection rate for this pipeline? Should it be 5% of the total number of welds, which includes both socket welds and butt welds, or only of the butt welds? 2. Is it only necessary to inspect the butt welds for flaw detection? The poster believes that butt welds and socket welds are separate; out of 100 joints, 80 are butt welds and 20 are socket welds, so it is necessary to inspect 4 butt welds and 1 socket weld. Could someone knowledgeable please let me know? I checked GB5018 and SH3501, but neither of them provides detailed descriptions for this aspect.

Radiographic and ultrasonic testing cover all areas of the butt welds, with surface inspection included!

I don’t know either. Is there anyone who can solve this? It is recommended to have the design institute issue a statement
