Selection of opening reinforcement and branch base
Thread Content
Could you explain in more detail under what circumstances reinforcement is possible and under what circumstances it isn’t? The same applies to branch pipe bases (the distinction between butt-welded and socket-welded types), as well as factors such as the medium, temperature, and pressure. It seems there are no clear regulations on this It seems there are also open-welding and open-reinforcement types as well. . . Crazy~!
https://bbs.hcbbs.com/thread-324245-1-1.html There is an explanation in this post~~~ Specifically, clauses 6.4 of GB50316-2000 and clause 8.7 of SH/T 3059-2012 provide sufficient details on the reinforcement for branch pipe connections; you can find information there to study~~~~
