Issues regarding the format of the permit seal for pressure pipeline design

2019-07-18View Original

Thread Content

I’m not a pipeline professional; I’ve been working on the documentation needed for renewing the certification for pressure pipelines recently. The previous format for permission seals was based on TSG R1001-2008; now the standard has been updated to TSG 07-2019, but the new standard does not specify a format for seals. I would like to ask, what standard should be used for the format of seals?

Is the original standard considered invalid? Can it still be used?

There are no new ones; we can only use the original ones
