bg4.png [Discussion Post 5] Is the reinforcing ring the main pressure component? Many people are wrong 1. Regulations in TSG21-2016: The following components are the main pressure components of pressure vessels:: () A. Expansion joint B. Studs of M36 or above (including M36) C. Nominal diameter ≥ 250mm pipe, flange D. Reinforcing ring The answer is ABC Some people ask whether it is considered a pressure component? And the role of the threaded holes on the reinforcing ring? By extension, a. There are threaded holes on the same lifting lugs) b. Do the support pads and similar pads have to leave vent holes? c. If the vent holes are not opened and a small part is not welded, will it have the same effect?
This shouldn't be the case. The 2009 version of the capacitance regulations no longer uses the reinforcing ring as the main pressure component.
Yes, people who are often exposed to container design will not have this problem.
Some people also asked whether it is considered a pressure component? ——Are there also threaded holes on the reinforcing ring? ——Exhaust gases generated by welding ； Before the pressure test, compressed air is passed through to check the quality of the welds and some liner and liner structures (flanges, integral flanges, reinforced forgings). In the past, I always forgot to draw the leakage port. The workshop came to me and said that if you draw like this, the welding gas cannot escape, and there is no way to test the pressure.:@:@:@
Is it because the workshop master makes trouble for you? ;P Some of them are just common sense questions. Common sense is enough. * If you take it for granted, it is easy to miss it. Generally, good workshop masters are not serious and will remind you kindly. After all, part-time work is not easy.
It's difficult for di. I always forget to draw at that time :lol
Ventilation holes generally need to be opened, but the vent holes on the reinforcing rings and lifting lugs are not only used for exhaust but also for sealing. The others are used to discharge the hot gas generated during welding. They do not need to be opened, but they must be left open until they are not used for welding.
:Handshake A good colleague looks for the reasons within himself. People who are good will be bullied by others. I don’t know where this saying that suffering a loss is a blessing comes from. Is there anything special about the lining components, open holes or threaded holes?
I think it's okay to leave a small part of the support without opening the ventilation holes, but I just need to explain it to others. Because the standard says continuous welding. See picture
The opening is similar to the opening of the reinforcing ring. M10 deep 12 thread, leaving 6mm through hole
