Regarding the connections between containers and flanges
Thread Content
This post was last edited by Sammy_Wang on 2016-1-16 10:48. Which standards specify the requirements for flange connections? How is it generally designed?
Pipelines and pipe fittings are determined based on the process medium and its parameters; a single flange alone cannot determine the pipeline!
What I’m actually asking is whether a section of pipe connection is needed at the flange on the outer end of the container, and whether that pipe connection should be the same as that used in the overall pipeline system
Well, it seems I’m getting old:lol
Many regulations were mentioned upstairs. . . . Read it bit by bit
The structure within the first flange face starting from the equipment itself is considered part of the equipment’s specialized design; the material selection, type of connection, and inspection requirements for this section of piping are different from those of external pipelines. It could be seamless pipes, welded pipes, forged pipes, or it might be pipes that are integrally formed with flanges, as well as sleeve reinforcements, etc. This section of the take over is part of the pressure vessel. Even for the fittings of pipelines connected to the outside (material, outer diameter, standards used for the fittings such as 8163, 9948, etc.) ； However, the design, manufacturing, and inspection requirements for this type of takeover are very likely to be exactly the same.
Yes, I know that long butt-weld flanges don’t require pipes, right? When using other flanged connections, it falls under the equipment structure design; is it necessary to test the impact of these connections on the strength of the cylinder? Also, what are the criteria based on which the materials and design of this take over are chosen? Inspection should be carried out in accordance with the inspection requirements for containers, right?
It’s already very detailed! Thank you so much!
