1 General Provisions 1.0.1 This code is formulated to standardize the construction of vertical cylindrical welded steel tanks, guarantee the engineering quality and make it advanced in technology, cost-effective, safe and applicable. 1.0.2 This code is applicable to the construction of vertical cylindrical welded steel tank body at and close to normal pressure for storing petroleum and petrochemical products and other similar liquids, including accessories welded with the tank, but not applicable to the construction of buried tank, tank holding extremely and highly hazardous medium and artificial refrigerant fluid tank. 1.0.3 Tanks shall be constructed according to design documents. In case design documents are required to be revised, written consent of the original design organization shall be first obtained. 1.0.4 Prefabrication, installation and inspection of tanks shall be performed with qualified measuring tools with the same accuracy grade. 1.0.5 The construction of vertical cylindrical welded steel tanks shall not only meet those specified in this code, but also those in the current relevant standards of the nation. 2 Terms 2.0.1 Annular/sketch bottom plates The tank bottom plates at the outermost side of the lower part of the shell plate, including annular edge plates and non-annular edge plates. 2.0.2 Fixed roofs The tank roofs with peripheral parts connected, in fixed method, with the tank shell top, mainly including self-supporting cone roof, supporting cone roof and self-supporting dome roof etc.. 2.0.3 Floating roofs Roofs which lifts with the liquid level, including external floating roof and internal floating roof, and mainly being single-deck floating roof, double-deck floating roof, open-top bulk-headed floating roof and floating roof on floats etc.. 2.0.4 Wind girder Member arranged onto the shell to make it stronger to resist wind. 2.0.5 Auto vent The venting device which opens/closes automatically when the floating roof rises or restores to be in bracing state. 2.0.6 Floating roof drains Equipment which drains the rainwater on external floating roof out of the tank under normal conditions. 2.0.7 Stiffening ring The member arranged onto the shell to enhance the stability of tank shell and protect it against instability. 3 Material Acceptance 3.0.1 Materials and accessories selected for the construction of tanks must be provided with quality certificates and meet those specified in design documents.
