The process of swaging, as performed on the Abbey Etna Rotary Swager,
consists of hammering a piece of metal to reduce its diameter without
grinding or cutting.
Abbey Etna has built what is probably the largest swager of its type--
The 916 machine designed to accommodate 8" O.D. pipe. It is used by
Resistoflex at its Bay City, Michigan plant to reduce pipe around a
plastic liner. The largest lined pipe, until this machine was
developed, was 6".
