:L, please reply quickly, experts
There is a standard; I’m sorry, I can’t remember the standard number. It is generally used when connecting a pipe with a larger diameter to one with a smaller diameter, as it helps to strengthen the joint between the two pipes. The specifications for butt-welded branch pipe supports are also specified in the standards, and these specifications are very important when purchasing materials.
What the original poster is referring to are butt-welded saddles; the branch pipe support includes the saddle and a half-copy of the elbow. Both are intended for local reinforcement. Under normal circumstances, it is necessary for a specialist in mechanical engineering or material control to prepare a table of branch pipe connections, and the selection can be made from that table; if questions arise regarding standards, one should turn to the specialist in material control.
mss-sp97, as well as the corresponding domestic standards
This national standard GB/T19326 relates to welded branch pipe supports
