PIPE: Often one hand (G or C-hand) moving forward, sometimes tracing a narrower, rounder path. DUCT uses two parallel C-hands, emphasizing a wider, rectangular channel. TUBE: Can be similar to PIPE, often using a 'G' or 'C' handshape to show a hollow cylindrical object. DUCT specifically refers to a channel for services, whereas TUBE can be more general (e.g., a test tube)
