This page provides information on how dished heads supplied by Masteel UK Limited are produced.

Firstly the steel needs to be cut shape, normally with CNC plasma cutting machines or industrial circular shears. The method for producing the dished heads is either via a spinning process or pressing & flanging process (or a combination of the two).

Spinning

The steel disc is spun on a hydraulic lathe which is then pressed to a tool. This pressing and spinning motion determines the overall shape of the head. The tool can be set to have both the knuckle and spherical radius which allows for the dished head to be produced in one go.

Pressing & Flanging

The dished head is created by firstly being cold pressed into a spherical cap shape and then flanged which creates the knuckle radius and straight flange. The straight flange allows for the finished dished head to be welded to the pressure vessels main body.

Spinning & Flanging

Dished heads can also be manufactured using a combination of both processes, where the spherical radius is made via the spinning process and the knuckle is created under the flanging method.
