Abstract
A tank including at least first and second portions connected by a connection ring and weld seams obtained by means of a friction welding method. The connection ring includes at least a first cylindrical portion fitted in the end of the first portion, at least a first shoulder protruding toward the outer zone of the tank relative to the first cylindrical portion and at least a first transverse web positioned approximately in the same transverse plane as the first shoulder. According to this configuration, the first cylindrical portion and the transverse web ensure that the forces generated by a friction welding head during the production of the weld seam which enables the tank to be closed are absorbed.
