Abstract
A new procedure for constructing cryogenic storage tanks involves erecting a freestanding metal liner. The liner is sized and configured to withstand the hydraulic forces the concrete wall of the tank being poured without the need for temporary stiffeners on the inside surface of lower portions of the liner. Lateral tension ties can be connected to anchor ties on an outward surface of the liner and used to tie the liner to outer formwork. These ties may be spaced up to about 2 m apart. Studs can also be provided on the outer surface of the liner, and a cylindrical ring of cryogenic steel can be integrated into the liner.
Claims17
A storage tank for cryogenic liquids that has:
- a concrete wall with an inward-facing side;
- a steel liner on the inward-facing side of the concrete wall, the liner being sized and configured to withstand the forces of pouring the concrete wall without stiffeners attached to the interior surface of the liner in lower portions of the tank.
A method for building a storage tank for cryogenic liquids that uses the steps of:
- erecting a freestanding inner steel liner;
- and
- pouring an outer concrete wall against the liner without adding temporary stiffening to the interior surface of lower portions of the liner.
