Specifies requirements for coating for protection against corrosion, where the coating is not subject to weather exposure (a safe period of 18 months of weather exposure is allowed for to cover an extended storage period prior to installation), and the pipeline operating temperatures are not above +60°C nor below -40°C. Coating thickness for normal and heavy duty for a given range of nominal pipe sizes are tabulated.
