Regarding the classification of industrial pipelines in TSG07-2019
Thread Content
The \"Rules for Licensing Production and Filling Units of Special Equipment\" TSG07-2019 came into effect on June 1, 2019, while the \"Rules for Licensing the Design of Pressure Vessels and Pressure Pipelines\" TSG R1001-2009 was simultaneously repealed； In TSG07, the classification of industrial pipelines eliminates GC3; instead, the GD category is included within industrial pipelines as GCD category ； So, according to the new licensing rules, which category among GC1, GC2, and GCD should the original GC3 class of pipelines be classified under? I was wondering if any colleagues who have conducted training on this standard could explain it.
Was this said during the presentation? Are it your own institution’s rules?
It’s all clearly written in the document; there’s no need for any further explanation or for anyone to issue regulations
According to you all, has the regulation TSGD0001-2009 become invalid? GC3 still exists in the regulations
The Regulatory Authority replied that it should be classified under GC2
The document states the process pipelines except for GC1. So how is a \"process pipeline\" defined? Do steam, nitrogen, and compressed air not need to be classified as pressure pipelines?
You’ve chosen the wrong term to use here; steam and nitrogen are also part of the process pipelines
Standards also vary from one source to another, each forming its own school of thought. I don’t even know which one to follow for implementation:L
The new version shall prevail. There are many standards and technical regulations related to the same issue, and they are not updated on the same day.
It will not become ineffective; testing according to GC2 is sufficient
