Can a large tube be placed directly on top of a small tube?
Thread Content
Can a larger pipe be installed directly on top of a smaller one? For example, can a DN700 gas pipeline be placed on top of a DN500 pipeline? I’m referring to the situation where it’s supported by angle steel brackets mounted on the DN500 pipe.
I’ve never seen small branches alongside large ones; I’ve only seen large branches with small ones. In your case, where the diameter of the small tubes is 500 and that of the large tubes is 700, it’s best not for them to support each other. By generally speaking, small tubes refer to those with very small diameters and light weight, and such tubes can be supported by larger tubes
It is generally not advisable to use a mounting method in which larger pipes are connected to smaller ones; such a method has a significant impact on the stresses and gravitational forces experienced by the smaller pipes, and it can easily cause damage to them. If the temperatures of the two pipes are different, they must not be installed together.
It would be better to use spring supports in this case!~ This post was last edited by qq375170364 on 2009-4-8 at 18:22.]
It is best not to use large pipes with small branches; it is recommended to set up scaffolding from the structure or the ground to support the pipes
No, the weight of the large pipes, acting as a concentrated load, can cause insufficient deformation in the smaller pipes
According to the standards, only the larger tube should be behind the smaller one; it is not allowed for the smaller tube to be behind the larger one.
No, large pipes must never be placed on top of smaller ones!
It’s better to modify the piping by placing the 700mm large pipe at the bottom.
