Can the tower internals be installed at the manufacturer’s facility and then transported as a whole to the project site?

As the title suggests, can the tower internals be installed at the manufacturer’s facility and then transported as a whole to the project site? I have seen some towers in which, after being manufactured in the factory, the internal components are installed horizontally right away. Is this approach in compliance with the regulatory requirements? Does anyone have experience in this area? Let’s discuss it together
No, deformation occurs during transportation (to a greater or lesser extent), and after it is lifted into place, it is necessary to adjust the balance and gaps of the tray(s) (the internal components of the tower) layer by layer, which is time-consuming and labor-intensive with poor results.
Those that are welded directly to the cylinder and involve heat treatment are generally assembled and welded at the manufacturing plant. Other components such as trays and packing are assembled or filled on-site; especially for measuring instruments, most of them are assembled on-site, though some are pre-assembled in the manufacturing plant and then shipped in separate packages.
I agree with the view from the third floor: aside from the supports, the internal components of the tower can be welded together at the manufacturing plant, but items such as collection trays and liquid distribution pipes need to be installed on-site. Not to mention the packing, as it is necessary to ensure levelness in order to prevent uneven flow
The deformation issues during transportation must be taken into account, as well as factors such as the installation location and verticality. Collecting trays, liquid distribution pipes, tray plates, and similar components are generally installed on-site.
It makes no sense to do this, unless the tower starts operating right over there; another factor to consider is the diameter of the tower – the larger the diameter, the less suitable it is to transport it together. Additionally, when transporting the tower plates separately, it’s essential to take proper protective measures.
Yes, as long as the installation accuracy is ensured
Hello, have you done this before?
Generally, if the tower has a small volume and involves fewer fillers, it is possible to consider installing it first before transporting it; otherwise, installation on-site is preferred.
The trays are generally pre-assembled in the container factory and then disassembled for on-site installation. The packing and the corresponding internal components are generally installed on-site. The demister can be assembled inside the tower and then transported horizontally to the site; this requires special design. If the tower diameter is larger, we do not recommend horizontal transportation.
