The overlooked aspects in pressure vessel regulation

The last edit to this post was made by ftxswb on 2020-11-24 at 12:09. China has established comprehensive laws and regulations regarding the manufacturing, sales, and use of special equipment such as pressure vessels; yet there is one type of pressure vessel that has been forgotten by many people； The blowing air tank of bag filters typically operates at a pressure of 0.4–0.8 MPa, with a volume ranging from 0.015 to over 1 cubic meter; the medium used is compressed air ； According to the requirements of TSG21-2016, containers with a volume of 0.03 cubic meters or more should be regulated in accordance with this standard (they can at least be classified as simple pressure vessels). In reality, however, only a small portion of such containers are manufactured and inspected in compliance with these regulations, while the entities that use them fail to carry out registration procedures or regular inspections. During inspections of special equipment, no one checks such containers either. Please share your personal views on this phenomenon.
There are countless things that can’t be found, and besides, the inspectors lack the professional expertise. Those who have worked in quality supervision for a long time can understand things to some extent, while those from the industry and commerce department either dare not take action or act carelessly.
There are many similar devices; pressure vessels that are easy to overlook can be found in various equipment such as air compressors, dryers, refrigerators, and central air conditioning systems. Regulatory authorities in some areas conduct targeted inspections, while there are many places that remain unregulated.
Could there be other reasons as well? Such devices pose less risk, and their installation locations are special and difficult to monitor; furthermore, out of considerations for local protectionism, the places where they are manufactured turn a blind eye to this situation.
When something goes wrong, nothing can be hidden!
In China, seed sowing equipment such as pressure vessels – are pressure vessels considered seed sowing equipment?
"Seeding equipment“?:dizzy:i I don’t quite understand it
Would it be better to classify seeding equipment as special equipment?
Think hard to deepen your understanding； Thank you.
