High pressure structure made of rings with peripheral weldments of reduced thickness
This patent describes a circular cylindrical solid walled metal shell with inner and outer surfaces and being capable of withstanding an internal pressure for which the shell is designed. It comprises: the cylindrical shell, comprising a series of consecutive metal rings of essentially equal maximum thickness positioned in axial arrangement with abutting ends of adjacent rings being joined together by a weldment; and with the axial length of the cylindrical shell portion, comprising the abutting end portions of adjacent rings, and the weldment being a full thickness weldment joining the abutting ends together having a reduced thickness which is not more than about 0.90 of the maximum thickness of the rings.
