T/CCSAS 046-2023 Guidelines for leak detection implementation of atmospheric pressure vertical cylindrical welded steel storage tank
Basic Information
Scope
This document provides the general requirements for the implementation of leak detection for atmospheric-pressure vertical cylindrical steel welded storage tanks (hereinafter referred to as "atmospheric-pressure storage tanks"), preparations before leak detection, on-site detection, result analysis and evaluation requirements, as well as the detection report. This document is applicable to the implementation of leak detection for the main bodies of atmospheric-pressure storage tanks used for on-ground storage of petroleum, petrochemical products, and other similar liquids. This document is not applicable to the implementation of leak detection for accessories such as storage tank sealing systems, breathing valves, central drainage pipes, and heaters.
