Is there a way to inspect gasket? please help

Hi, my name is Nouris and i'm still new in oil and gas industry. I asked my senior about how to inspect gasket, can we do it while doing in-line inspection with Pig tools.. and he said we cant. So can anybody give me an enlightment about how to inspect it or we really cant inspect it? since there are few case on pipeline failure involving gasket..

thank you :untroubled::untroubled:
