Piping rack selection issue
Thread Content
When setting up pipe racks, F8 type supports are required at locations where bends are present. However, there are issues with the diameter of the support legs. By referring to the calculations for support legs in the appendix of HG/T20629-1999, it was found that no standard guidelines are available for pipes with a diameter of DN80 or less. What should be done in cases where a supported pipe has a DN50 diameter? Is it feasible to use DN32 pipes for support? Please ask an expert for help! :handshake
There are no standards to refer to, so it can be calculated manually. It’s impossible for standards to list all specifications; if you don’t know how to calculate it, simply use the value from the higher level
There is no standard for pipes below DN50; they are designed on-site according to the specific requirements.

Reply to 4# predatoryou: There’s no need to include the materials and locations in the diagram; if you include them in the diagram, how can it still be called on-site design?
Are there any experts who are skilled at working with tube machines to help answer this? Thanks first!

If you don’t focus on standards, you won’t be able to make pipe racks. Think about how heavy a DN50 pipe can be if there are no valves on it.
Reply to 8# ddc8325: It seems you’re an expert. Could you share some pictures as a reference? :handshake
Reply 9# predatoryou: There are no pictures. I can’t even be called a hero. In my opinion, for pipe racks, unless stress calculations are required, the dimensions of the rest of the components can be fairly large; as long as the stress requirements are met, along with considerations of aesthetics and simplicity, that’s sufficient.
If such a pipe rack is truly necessary, use pipes of DN40 size as the support. Alternatively, support it with a T-type pipe rack 50+ mm away from the horizontal weld of the elbow.
