Should pipe supports be installed for non-insulated pipes, such as overhead circulating water pipes?

Circulating water does not require pipe supports, as the pipes for circulating water do not need insulation and the water in the pipes is in a flowing state.
Generally, we do not use pipe supports for carbon steel pipes that are not insulated
You can add pipe supports as needed on site; there is no strict requirement.
In my opinion, if it’s a very large pipe, pipe supports should still be installed, even if it isn’t insulated.
For non-insulated pipes, it depends on whether the pipe is made of stainless steel or carbon steel; structural steel pipes are generally made of carbon steel. If the pipe is made of stainless steel or alloy steel, it is advisable to use pipe supports to prevent corrosion (reputable design firms with strict standards require this). For carbon steel pipes used in systems such as circulating water, pipe supports may not be necessary.
It’s not necessary to add them, but it’s better to include a few. There’s no need to add one at each point; otherwise, a long tube with sections hanging in the air will deform, which isn’t ideal. There’s no strict rule regarding this
It is very necessary to design pipe supports, because when the pipes start transporting fluid, vibrations may occur, leading to displacement of the pipes.
It depends on the size of the pipe, as water pipes are all thin-walled; if they are too large, it can lead to local deformation of the pipe. It is necessary to use pipe supports.
Generally, pipe supports are not used, but some projects specify that they are required when the diameter exceeds a certain value; it depends on the specific project requirements, as there are no clear guidelines elsewhere
The circulating water pipe is DN400; the contractor failed to install pipe supports. I had intended to have them installed, but it seems there is no basis for doing so, so it’s fine as it is. But it’s not clear whether it needs to be fixed or guided on the bracket.
