Abstract: The vessel of the invention includes a side wall and an end wall, and is characterized in that the end wall is a domed end wall, of thickness EI including an inner layer CI providing corrosion resistance and an outer layer CE of thickness EE at least equal to the thickness EI of the inner layer CI. The inner and outer layers are rigidly joined by a first assembly device. Inner layer CI is formed from a multilayer material including an internal layer CI for providing corrosion resistance and an external layer CIS, the internal CIC and the external CIS layers being rigidly joined by a second assembly device. The invention enables inexpensive manufacture of large vessels.
