The thick-wall extrusions illustrated were known as ‘tube shells’ and were processed into thin-wall tubes to the sizes used in domestic heating systems by means of ‘drawing’, or pulling, the tubes through a series of reduction dies until the final drawn size was achieved. Naturally, the length increased with each drawing operation.
