scope:
The provisions herein supplement API Standard 620 and form a guide for materials, design, and fabrication of tanks to be used for storage of refrigerated products.
A refrigerated tank may be a single-wall insulated tank or a double-wall tank consisting of an inner tank for storing the refrigerated liquid and an outer tank enclosing an insulation space (usually having a lower gas pressure) around the inner tank. A double-wall tank is a composite tank and the outer tank is not required to contain the product of the inner tank. In a double-wall tank, differences in materials, design, and testing exist between the inner and outer tanks.
