Preset Edges of pressure vessel shell

This, the first of two short videos shows the edges of boilerplate being pressed to prepare the edges so there is no flattening at the seam – ready to be used on our bronx pyramid roll set.
The plate is 20 mm thick BS 1501 225 490B LT50 and is at the maximum capacity for these rolls:

Other grades of carbon steel plate used for pressure vessels include :

ASME SA516 Gr. 70 ASTM A516 Gr. 70 EN 10028-3 P355NH
EN 10028-3 P355NL1 EN 10028-3 P355NL2 BS 1501 223 490B LT30
BS 1501 224 490B LT50 BS 1501 225 490B LT50 ASME SA537 Class 1
ASTM A537 Class 1 ASME SA516 Gr. 65 ASTM A516 Gr. 65
