The metal pipe effect is a generic recorded impact rather than a line or scene from a single film or show, which is why it appears in so many unrelated edits. Short, loud and instantly recognizable, it spread online as a meme sound for drops, fails and exaggerated accidents, where its hollow clang works even without context. Creators keep returning to it because the noise is easy to place, easy to recognize and funny precisely because it sounds far too heavy for the small mishap on screen.
