What are the licensing levels and scope for pressure pipelines in the new TSG07-2019?
Thread Content
As the title suggests, the new version of the standards only sets out the requirements for obtaining permission to install pressure pipelines, unlike TSG D3001-2009 which specifies the levels and scope of permission for such installations. I found a table online; does anyone know which standard this table originates from?
TSG07-2019 P178
This is the content from Annex 1, \"List of Licenses for Special Equipment Production Units\", of the \"Announcement by the State Administration for Market Regulation on Matters Related to Administrative Licenses for Special Equipment (No. 3, 2019)\"
The TSG07 standard downloaded from the Technical Supervision Bureau’s website consists of 173 pages in total – is my version incorrect?
TSG07 was released later than this document; how should this be understood? The new version of TSG07-2019 does not specify the classification of pressure pipelines; can we refer to the document issued by the General Administration in this regard?
The preface to TSG07-2019 explicitly states that one of the bases for the \"Licensing Rules\" is the \"Catalogue of Licensed Units for Special Equipment Production\", and this catalogue is Annex 1 to Document No. 3 of 2019
For the classification of pressure pipelines, refer to GB/T20801.1-2020, which represents the latest classification system for such pipelines; the GC3 category has been removed.
