Issues regarding the installation of supports and hangers for soda water pipelines
Thread Content
I have a question for the brothers on the forum. Recently, while looking up design manuals for supports and hangers used in steam and water pipelines in thermal power plants, I noticed that when selecting such supports and hangers, it is stated that hangers can withstand greater forces than brackets. I’m really confused by this. For example, when I use the G43 double-channel steel triangular frame, I think the forces acting on it should be the same; then why can hangers withstand greater forces than brackets? ? ? Waiting online for expert advice. . . . . . . . . . . . . . . . . . . . . .
Asanami, the bracket itself needs to bear its own weight, while the hanger does not need to take its own weight into consideration. It’s like the issue of destructive force between positive pressure and negative pressure
Hangers are more stable than brackets, and therefore can withstand greater forces.
Is it because the hanger distributes the load more evenly than the bracket?
Pillars have stability issues; instability must be taken into account, and there are requirements regarding the slenderness ratio. There is no stability issue with the tie rod. Therefore, the force exerted on the tie rod is greater than that on the compression rod. Just look at the textbook on Mechanics of Materials and you’ll understand.
I disagree with what the brother on the sixth floor said; you claim that there is no stability issue with the tie rods. So I fully agree that the force exerted on the tie rod is greater than that on the compression rod, but there is no compression rod in the bracket; it’s not a matter of rods at all. The brackets mentioned here refer mainly to things like tube supports. So I think the reason why brackets bear less force than hangers is that, in addition to having to withstand the same force (vertical load) as hangers, brackets also have to endure forces that hangers do not have to face (lateral thrust).
I’m curious to hear what everyone thinks of me; we can discuss it together
With the same force applied, it’s probably the tensile and compressive strength of the materials that differ, right?:victory: :loveliness:
Hangers can not only absorb vertical forces but also the expansion forces resulting from changes in the pipeline direction.
The tensile strength of this material is very high, but I’m not sure about its specific performance yet; I need to do some further research
