AS 4822:2018 PDF

This Standard sets out minimum requirements for the field joint coating (FJC) of seamless and welded steel buried onshore pipelines.

This Standard was prepared by the Australian members of the Standards Australia/Standards New Zealand Committee ME-038, Petroleum Pipelines, to supersede AS 4822—2008.

The objective of this Standard is to provide manufacturers, suppliers, specifiers and users of oil and gas pipelines information on the application of and testing requirements for external field joint coatings (FJCs) of seamless or welded steel pipelines for onshore steel pipelines.

This revision updates requirements taking into account the latest version of ISO 21809-3, Petroleum and natural gas industries — External coatings for buried or submerged pipelines used in pipeline transportation systems, Part 3: Field joint coatings, and includes a new joint coating type, Amorphous low viscosity polyolefin coating.
