A method and an apparatus for swaging a metallic embossed pipe to form concavities in its wall units, wherein, a die core made from a holding pipe having surface meshes and a plastisol filler is provided in the metallic pipe mounted in a circularly swaging apparatus having two positioning seats respectively movably provided on two ends of a slide way and can absorb swaging pressure exerted on the pipe wall, some swage processing seats movably provided between the positioning seats clamp the embossed pipe and position it accurately in an axis line; the processing seats press synchronically inwardly in a radiant array to swage the embossed pipe, thus the concaved pipe wall units are formed, the pipe hole and the die core are then slightly heated to draw the holding pipe and plastisol out to complete the process for swaging and forming the concaved wall units.
