Method for determining the inspection ratio of pressure pipelines
Thread Content
After the implementation of the \"Announcement by the State Administration for Market Regulation on Matters Related to Administrative Licenses for Special Equipment,\" there are certain issues regarding the criteria used to determine the inspection rate for pressure pipelines. In the case of CO as a medium, in accordance with the \"Announcement by the State Administration for Market Regulation on Matters Related to Administrative Licenses for Special Equipment\" (Announcement No. 3 of 2019 issued by the State Administration for Market Regulation), the \"Catalogue of Hazardous Chemicals 2015\" is applied, classifying it as Category 3*, which corresponds to GC2. However, if the inspection rate for such media is determined based on GC2 standards, it will be lower than that specified in the original GB50184-2011 standard, which is based on the classification of highly hazardous media. At present, there is no connection between the old and new standards; it is unclear which standard should be applied for toxicity assessments. I would appreciate any guidance on this matter.
There are official authoritative explanations in the documents
Since the inspection standards have not been updated, it must be done in accordance with the current ones. But overall, the regulations are becoming increasingly strict. Although according to the new rules CO is classified as Category 3*, it was previously categorized as GC1 due to its high toxicity; now that it has been downgraded, I’m not sure what to think.
Does the standard require any further official authoritative interpretation?
