Cold Pilger Rolling: Part One :: Total Materia Article

Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tubes in one process step. Depending on the material, the cold pilger process achieves cross-sectional reductions of more than 90 percent in a single

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.

Introducing cold pilger mill technology - The Fabricator

2006-7-11  The rolling tools in the cold pilger process comprise a pair of ring dies and a mandrel. The mandrel is located inside the tube in a fixed position and rotated by the mandrel thrust block. The mandrel itself is tapered in the rolling direction. The dies have matching grooves on their circumferences.

The Düsseldorf-Rath Works - Vallourec

2020-6-5  The pilger rolling process was patented by Max Mannesmann as early as 1891. It owes its name to the discontinuous procedure of the process – two steps forward, one back – which resembles the pilgrims’ dancing procession in the Luxembourg town of Echternach. History The rolling mill at the Düsseldorf-Rath location took up production in ...
