Equipment (internal pipe gallery in the unit) — Where to? (12)

Thread Content

Dear listeners, I was unable to return to post earlier in the morning due to personal reasons, which caused you to wait for a while. I came back this afternoon and rushed to make up for it right away; I hope you can understand. A few days ago, some forum members asked in their messages about the layout of the pipe racks. Since the issue of pipe rack layout was mentioned in previous posts, it wasn’t explained in detail there; therefore, this section will provide a thorough explanation of the layout of the pipe racks inside the facility. As for the overall pipe racks in the factory area outside the facility, if there is no unified design by a specialized team, this guide can still be used as a reference, but it’s important to take into account the dimensions and height requirements of the pipe racks. Enough, back to the main topic: the internal pipe gallery in the device. Issue 12: Layout of the internal pipe corridors in the facility. Here, I’ll discuss the layout of these internal pipe corridors by building on what was covered in 20546, adding anything that wasn’t mentioned or that is particularly important. It’s mostly my own thoughts and experiences; I wouldn’t call them experiences per se, but they are certainly lessons learned. The most important point I want to mention is \"directional offset\". I’ve seen that this problem occurs in many projects and drawings: the pipe gallery changes direction, but it still remains at the same elevation. First of all, the spacing between layers of a multi-layer pipe gallery should be determined based on the diameter of the pipes and the structure of the pipe supports; the spacing between upper and lower layers is generally between 1.2m and 2.4m, while for larger installations it’s between 2.5m and 3.0m. When there is a directional offset, the height difference between the layers is usually between 0.6m and 1.2m. For large, thick pipes, there’s an empirical rule stating that the clear distance between the upper and lower bends should be twice that value. Here are some diagrams of the pipe racks, but the layering difference isn’t very apparent yet. Everyone should pay attention to their own installations, especially in areas where there are multiple layers of pipe racks and where they meet multiple users’ systems, as the layering difference is quite significant there. Incidentally, it shows the main road being raised to 4.5m to accommodate large fire trucks. The image above. It should be reiterated that when planning the layout of utility tunnels, it is essential to consider in advance the required spacing between underground pipes, fire-fighting equipment, underground piping systems, cable trenches, as well as buildings and structures, and the utility tunnels. I’ve suffered from this many times: once the construction was almost complete, they suddenly decided to lay a pipeline, which required various excavations; the foundations were almost left hanging. Another time, the foundations for the pipe gallery were already ready, but when it came time to install the steel structure in the following year, they said they needed to add a pump room between the equipment and the pipe gallery. Even worse, the local electricity department had approved the use of armored cables buried directly within the factory area, but since space was already limited, they informed us at the end of construction that this wasn’t allowed and that a separate cable trench had to be created. Good heavens, these are all lessons learned through pain and suffering; I urge everyone who is sensible to take these lessons to heart. There are three lessons: first, leave a change area when making the layout. Second, always rely on the meeting minutes no matter who you are dealing with; no one is your mother. Third, organize the construction sequence properly to avoid digging and then filling back again. The internal pipe gallery should focus on the core equipment of the installation as well as those systems with a large number of pipes; for example, in the Feto project, one reactor alone has over 100 pipes, so these systems naturally take precedence, as they involve a large number of pipes. The previous picture. Finally, let’s talk about span and column spacing. Regarding pipe galleries, the span is generally between 6 and 9 meters; it should be determined based on the size of the pipes – larger pipes require a larger span, while smaller pipes need a smaller one. By the way, regarding things like the span of buildings, everyone faces issues related to the length, width, depth, and height of factory buildings; I see that many people have also asked about this in HaiChuan. Unless there are special requirements, refer to the dimensions in the figure below; it’s quite difficult to find this. ---------------------------------------I am a divider line------------------------------------- Where to go with the device?
