Reservoir of feeble unitary weight particularly useful in the storage of fluids under pressure and method for its manufacture.

摘要

The present invention describes a vessel for fluids under pressure and a method for manufacturing it. The vessel is composed of two bottoms (3, 4) separated by a corrugated cylindrical zone (2), the corrugated cylindrical zone being strengthened circumferentially, and of a longitudinal reinforcement (7) which is placed on the outer structure of the vessel as a whole and which, by absorbing the bottom effect, makes it possible to reduce the thickness of the bottoms and make the vessel lighter. <IMAGE>
