Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.
