Relative merits of multilayer and thick solid-walled vessels

3 Relative merits of multilayer and thick solid Walled vessels [4] 

In comparing the two types of vessel, consideration should also be given to properties such as the tensile strength, yield strength, ductility, homogeneity 

Finally mention must be made of some problems which are specific to multilayered technology and which have no parallel in the solid-wall situation. 

As can be seen from Table 8.2, each element of the multilayer wall consists of a sheet of thin metal which is wound tightly round proceeding sheets after being rounded in a bending machine without the help of bending moulding. It 

A further criterion for assessing multilayer vessel design and fabrication is, without doubt, the effective thermal conductivity of the vessel wall. The transfer of heat through the wall is more or less hindered by the layered cylinder design according to whether contact between the layers is poor or good.
