FRP tower platforms and supports
Thread Content
The company currently has a fiberglass-reinforced plastic tower with a diameter of 1800 and a height of 27 meters. The manhole is located at a height of 20 meters. The pipes in the tower are 500 mm in diameter and made of fiberglass-reinforced plastic; how is this pipe supported from the bottom to the top of the tower? The design institute only provided the operating condition diagram; nothing was covered regarding other installation and maintenance tasks! How to build a maintenance platform and pipe supports for this! !
For this, a truss-type pipe rack is needed, similar to the exhaust stack of a chimney. Of course, the equipment itself requires a platform; it’s best to use the equipment’s existing platform.
Install supports along the tower body, a fixing frame at the top of the tower, and other guiding or spring frames
What concerns me more is how to construct the supports for large fiberglass vertical pipes A load-bearing frame must definitely be constructed, and its construction is more complex than that of a guiding frame ； The specifications state that load-bearing supports cannot be bonded onto the pipes (HG 20520 Guidelines for the Design of FR-PVC Composite Pipes). For smaller pipes, rubber gasketed clamps can be used as fixing supports; however, for larger pipes, the weight is so great that clamps seem to be unsuitable I also ask everyone to conduct in-depth discussions on the issue of fiberglass pipe supports based on past experience.

Additionally, in cases where the main structure of tall structures is made of materials that cannot withstand large shear forces, a multi-layered enclosure platform is generally required to meet wind and seismic resistance requirements. The pipeline operation platform and supports for the heat exchanger piping should be designed in conjunction with the main equipment platform, sharing a single platform.
The equipment needed has now been installed, and the pipes have also been prefabricated! Now, with the lifting operation, there are concerns regarding this support, and the foundation design for the equipment platform has not yet been completed~
The tower is now completely bare; it can’t do anything! One can only build the foundation separately and create a platform! The bracket has been installed!
This is really on the mark; are there any relevant cases? We are also discussing wind resistance in this regard; we’re not concerned about the towers, but rather these large pipelines. In fact, there are also several pipelines with a diameter of less than 100 mm that lack support as well. For the smaller pipelines, it is planned to use clamps instead! It seems this has to be done now! It’s just that the design institute didn’t provide any specific details~

I don’t have much experience either； The current approach is to wait until the design of the large pipes is basically finalized and no longer changes, and then assign the task of providing support to the manufacturer. In typical pipeline designs, the pipelines determine the requirements for the structure; but when this task is assigned to the manufacturer, it is necessary to provide them with the design specifications for the structural supports (which is the reverse of the usual process) ； But I always feel uncomfortable doing things in a technical way like this. That’s why I have been paying close attention to this topic, hoping that other insightful people from Haichuan can offer constructive suggestions.
The main frame is made of steel structure or concrete framework; the main equipment is supported by lateral springs. It is recommended to install expansion joints in the vertical air ducts for adjustment, fixed supports are used on the middle platform, while movable supports are used at the top and bottom
