In accordance with TSG D0001-2009 \"Regulations on Safety Supervision of Pressure Pipelines – Industrial Pipelines\" and GB 50235-2010 \"Code for Construction of Industrial Metal Pipelines\", pipelines that transport extremely hazardous, highly hazardous fluids, or flammable fluids must undergo leakage tests. However, the later standard SH 3501-2011 \"Code for Construction and Acceptance of Steel Piping Projects for Toxic and Flammable Media in the Petrochemical Industry\" specifies that Class C liquids with working temperatures below 60 degrees are an exception; the requirements of this industry standard are lower than those of the national standard, but in fact they are more reasonable. Hey, how do you implement this in practice?
Be strict when doing it, and act innocent by being lenient during inspection
TSG D0001-2009 \"Regulations on Safety Supervision of Pressure Piping – Industrial Piping\" represents the most fundamental requirements, and these must not be violated. The GB/T20801 standard cited in this regulation is also mandatory; as for other standards, their selection depends on the design requirements
