RELATIVELY THICK-WALLED VACUUM-RESISTANT AND PRESSURE-RESISTANT VESSEL

摘要

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 E_I including an inner layer C_I providing corrosion resistance and an outer layer CE of thickness EE at least equal to the thickness E_I of the inner layer C_I. The inner and outer layers are rigidly joined by a first assembly device. Inner layer C_I is formed from a multilayer material including an internal layer C_I for providing corrosion resistance and an external layer C_IS, the internal C_IC and the external C_IS layers being rigidly joined by a second assembly device. The invention enables inexpensive manufacture of large vessels.
