ABSTRACT:
A multilayer pressure vessel comprising a cylindrical portion formed by a pipe with roll strips wound on said pipe and welded to the bottom of the vessel and to its flange for the cover. Said roll strips are wound in layers along a helical line so that each subsequent layer is wound in a direction opposite to the preceding layer at a pitch of 0.2 to 2.2 of the inside diameter of the pipe. The adjacent coils are welded to each other on a helical line only in the roll strip forming the external layer.
The multilayer vessel according to the invention is considerably cheaper to manufacture than the known vessels.
