GB/T 21447-2018: Translated English of Chinese Standard. (GBT 21447-2018, GB/T21447-2018, GBT21447-2018): Specifications for steel pipeline external corrosion control
https://www.chinesestandard.net, 2018 M10 5 - 33 pages
This Standard specifies the minimum requirements for the design, construction, and management, etc. of steel pipeline external corrosion control engineering, including basic provisions, anticorrosion coating design, cathodic protection design, interference mitigation, construction and acceptance, operation and maintenance management, and other contents. This Standard is applicable to the external corrosion control of oil, gas, and water pipelines, which are newly-built, expanded, and re-built overland and subsea, with conveying medium temperature of less than 100 Celcius.
