Attention! A large number of pressure vessels that previously did not require test plates now need to have them
Thread Content
Compared with the previous version HG/T 20660-2010, HG/T 20660-2017 \"Classification Standards for Toxicity Hazards and Explosion Risks of Chemical Media in Pressure Vessels\" classifies many media as having high hazards instead of moderate hazards; carbon monoxide (CO) is the most typical example. In accordance with clause a of 9.1.1.1 in GB/T150/4, pressure vessels containing media with extreme or high hazard levels require the use of product test plates. As a result, many containers that previously did not require the creation of product test plates now need to have such plates made, thanks to the issuance of HG/T 20660-2017. Those working in pressure vessel design must pay close attention to this; I almost made the same mistake! This is a reminder.
Even after learning it, experiments still need to be done~~~~
There is a theory that the 20660 mentioned in Rong Gui Shang refers to a specific time frame, so it’s still possible to proceed according to the moderate approach. Although our company is following the guidelines set for 2017 at present, the past can also be explained by referring to those earlier guidelines

Thank you to the original poster for the reminder; I’m keeping an eye on it·
Version 17 is not being used now; the old version is still in use!
I would like to ask, in actual production, how much impact does making product test samples have on the quality of the products?
Strict testing requirements can be set, but it makes no sense to simply use product test samples – it’s done merely to meet the standards. (Saying this might seem irresponsible.)
It has been clarified that it should be implemented in accordance with the 2000 version, so there’s no need to get excited:lol
You’re in trouble yourself, yet still remember to warn those by the well. Like it!
I’ve learned it; thanks to the person in the pit for the reminder.
