ABSTRACT:
The present invention relates to a method for the manufacturing of very high pressure vessels so that they survive high cycle fatigue loading. In particular, the method requires creating a residual tangential stress at a bore radius of a vessel such that the stress under load is more compressive than a maximum applied internal pressure. Furthermore, the method may require creating a residual stress a the inner radii of the supporting jackets such that the stress under load is compressive or zero.
