A pressure vessel and a method for distributing the stresses in a thick-walled high-pressure vessel, so that they lie within allowable limits, by constructing the wall in a series of generally concentric layers, at least one intermediate layer of which is to be constructed before the other layers. The intermediate layer is constructed above a base, resting on it through a sliding joint. Then it is placed under an external prestressing pressure. Thereafter, that layer is secured to the base by a rigid concrete connection. The remaining layers of the wall are then constructed and are subjected to an external prestressing pressure. Preferably, stress-relieving slots are applied to the innermost layer, during its construction.

A thick-walled high-pressure vessel, in which the stresses lie within allowable limits, including in combination a series of generally concentric layers including at least one preconstructed intermediate layer initially resting on a base through a sliding joint, and, after application of an external prestressing pressure, is secured to the base by a rigid concrete connection, the remaining layers of said wall being thereafter constructed and stressed with an external prestressing pressure.
