1 Scope
This standard specifies the product structure, specifications and marks, general requirements, requirements, test methods and inspection rules, as well as marking, packaging, transport, storage and delivery certificates of steel-glass fiber reinforced plastic double-layer buried oil tanks.
This standard is applicable to double-layer buried oil tanks (hereinafter referred to as S/F double-layer oil tanks) which take steel as the inner shell and glass fiber reinforced plastic (formed by spraying technology) as the outer shell, for which a leak detector is installed in the gap formed between the inner shell and the outer shell, and which store gasoline, ethanol gasoline, diesel oil, aviation kerosene and aviation gasoline under normal pressure, with a filling factor of 0.9.
