How should the plug welding holes on the reinforcement ring be arranged, and how should their size be determined?

There are no plug-welding holes on the reinforcement ring; they are likely leak detection holes. This topic has been discussed many times already – take a look here: http://bbs.hcbbs.com/viewthread.php?tid=85866&highlight=%B2%B9%C7%BF%C8%A6

It’s a leak detection hole, right? Just an M10X1 screw hole is sufficient; there are no specific requirements regarding its placement

According to the regulations, reinforcement rings installed on pressure vessels by welding, as well as the gussets welded continuously around them to serve a reinforcing purpose, must have at least one threaded hole for leak detection, with a diameter of not less than M6.
