GB/T 26978-2021 Design and manufacture of site built,vertical,cylindrical,flat-bottomed steel tanks for the storage of cryogenic liquefied gas
Basic Information
Scope
This document specifies the general requirements for the design, construction, and installation of on-site assembled aboveground vertical cylindrical flat-bottomed steel main container storage tanks (including metal components, concrete components, insulation components, etc.), and describes the procedures and methods for testing, drying, displacement, and cooling of the storage tanks.
This document is applicable to low-temperature liquefied gases with a storage temperature range of -165°C to 0°C, including liquefied natural gas (LNG) and low-temperature liquefied petroleum gas (LPG) and other low-temperature refrigerated hydrocarbons, whose main components include methane, ethane, propane, butane, ethylene, propylene, etc.
This document is applicable to storage tanks with a maximum design pressure not exceeding 50 kPa.
This document is not applicable to storage tanks with concrete main containers.
