[ AS4822 ]

Something that you don’t think about when you think about pipelines (!), is to think about the bit between the individual (coated) pieces.  It’s the bit that’s the welded bit, where there’s no factory-applied protective coating.   

There’s some bare pipe there, after you’ve welded the separate bits together.  Now what?  Well, we apply “FJC” – Field Joint Coating.  And that’s where Australian Standard AS4822 comes in.  AS4822 provides requirements for products and the tests required to assure us the applied FJC will stand the test of time.  Then those field joints get buried along with the rest of the coated pipeline.
