Industritë e naftës dhe gazit natyror – Veshje të jashtme për tubacione nëntokësore dhe nënujore për sisteme transporti me tubacione - Pjesa 5: Veshje të jashtme prej betoni (ISO 21809-5:2017)
Petroleum and natural gas industries - External coatings for buried or submerged pipelines used in pipeline transportation systems - Part 5: External concrete coatings (ISO 21809-5:2017)
ISO 21809-5:2017 specifies the requirements for qualification, application, testing and handling of materials required for the application of reinforced concrete coating externally to either bare pipe or pre-coated pipe for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623.
The external application of concrete is primarily used for the negative buoyancy of pipes used in buried or submerged pipeline systems and/or for the mechanical protection of the pipe and its pre-coating.
ISO 21809-5:2017 is applicable to concrete thicknesses of 25 mm or greater.
