Pressure vessel assessment
Thread Content
This is the nameplate of a pressure vessel; according to the Pressure Vessel Regulations, it should be classified as a pressure vessel of the upper category, but the manufacturer classifies it as a simple pressure vessel. Is this appropriate?
It shouldn’t be correct; I’m not aware of the specific operating conditions. Preliminarily, it seems unreasonable, so it would be advisable to discuss this with the manufacturer
1. The manufacturing date of the equipment is December 2016; simple containers can be manufactured quickly, with a production cycle of no more than one month. It is preliminarily assumed that it falls under the scope of regulation specified in TSG21-2016. 2. In accordance with clause A2.3 of TSG21-2016, it can be preliminarily determined from the data on the nameplate that it belongs to a simple pressure vessel. 3. The product nameplate shall be manufactured in accordance with Appendix C of SG21-2016.

There is no issue with designing and manufacturing this product as a simple pressure vessel; as long as it meets the requirements of clause A2.3 of the Pressure Vessel Regulations, it can be designed and manufactured in that manner. I have checked, and it meets all the conditions specified in A2.3. Of course, since it is considered a simple pressure vessel, the prerequisite is that this product is manufactured in bulk; if it isn’t produced in bulk, it cannot be manufactured as a simple pressure vessel. Because simple pressure vessels must first pass type tests. The information on the nameplate of this product is still a bit too simple
See page 102 of TSG21-2016 for details
Obviously, there’s a stamp on the nameplate, which indicates that inspection has been carried out; that means it has been classified. It’s just that the information on the manufacturer’s nameplate might be too simple to notice. Let’s verify again.
These mass-produced items are likely to be simple pressure vessels; checking the quality certificate and inspection report will suffice.
Simple pressure vessels also fall under the category of pressure vessels; they just do not require registration
Simple pressure vessels also require manufacturing inspection, but registration is not necessary. Earlier, when monitoring installation was required, it wasn’t necessary to install monitoring either
