Classification of medium-pressure vessels
Thread Content
Dear experts, the \"Regulations on Safety Inspection of Pressure Vessels\" stipulate that: (2) Medium-pressure vessels (limited to those containing media with extremely high or high toxicity levels) are classified as Class III vessels. How should this be understood? As long as this requirement is met, does it mean it must be classified as Category III regardless of the product of pressure and volume?
Do experts no longer need to pay attention to the standard of \"Regulations on Safety Inspection of Pressure Vessels\" these days? Just look at the large capacity specifications
Many highly hazardous media now have their PV constraints reduced to Category 2 requirements, which is a benefit for manufacturers in Category D; however, the various requirements regarding manufacturing cannot be lowered.
Yes, but this is the classification standard for the 99 version of the regulatory specifications. Classification should now be carried out in accordance with the latest standard TSG21-2016, the Regulations on Fixed Pressure Vessels. According to TSG21-2016, medium-pressure vessels (Group 1 media) should be classified as Category II or Category III, with the specific classification depending on the P*V values.
