Issues regarding the support structure design for the section of the steam pipeline that passes through the fire wall
Thread Content
The DN150 steam pipeline must be properly sealed at the openings that pass through the fire wall, as required. So here’s the question: Option 1: The pipe cannot move up, down, left, right, or forward; it’s similar to a fixing frame, but the stress distribution might not be optimal. In that case, a fixing frame can be installed right next to it, so that the pipe at the opening doesn’t move or experience much stress – which is good. However, the piping system will need to be carefully arranged afterward, due to the presence of this fixing frame. Option 2: The pipe can only move back and forth, similar to a guide frame? Can fire-resistant walls be used for load-bearing purposes? What is the exact situation, and how should the pipe rack at the opening be designed?
No doors or windows should be created in the firewall; when it is necessary to do so, Class A fire-resistant doors and windows that are fixed in place or can close automatically in case of a fire must be used.

I think firewalls shouldn’t have a weight; pipes can be extended
In accordance with Article 6.1.6 of GB50016, steam pipes may pass through firewalls.
Would it be better to use the first option?
Can I add a few elbows at the wall penetration?
I think fixed fire-resistant doors and windows of Class A, or those that can close automatically in case of a fire, should be used. You can also refer to the answers from other users above; I have also learned * it
