Should the longitudinal and transverse elevations of the pipes in the entire system be staggered?

As the title suggests, under normal circumstances the elevation is changed along with the direction; however, in special cases a horizontal turn is allowed. What is the reason for this? Isn’t a horizontal turn something normal? Why is it only permitted in special cases?

If a pipeline makes a horizontal turn, in other words, if it turns from one side of the pipe rack to the other, it blocks the entire vertical channel; how can other pipes pass through then, unless they also make an up-and-down U-shaped turn? Many pipeline installation requirements dictate that the slope should be either constant upward or constant downward; U-shaped bends should be avoided as much as possible. This approach provides extensive practical experience in various aspects such as shutting down the system for material removal, preventing freezing, ensuring complete drainage, avoiding the formation of liquid or gas pockets, and preventing the accumulation of condensate and impurities ； On a smaller scale, it’s not allowed to block the longitudinal passage of a pipe. When making a longitudinal turn, it is generally done by rising half a layer or lowering half a layer before turning. The ceiling height is generally 1.2 meters or 1.4 meters, with a maximum of 2.0 meters; the elevation at half of this height is half of that value.
For eggs that are not transported through pipes, there’s probably no need to worry too much about this, after all, the pipes are quite long, and one or two bends don’t have much impact on the flexibility of the pipes
If the direction in which this pipe moves does not affect any other pipes, then there’s no need to do that, right?
Well, I’ve seen it. His main concern is not affecting the route of the other pipelines
This is just a standard practice, and it is certainly beneficial. But this actually also needs to be adjusted flexibly based on the actual layout of your site; the guidelines are merely a reference for us. However, any changes made should still be reasonable.
Yes, I just want to know the reason for following these standards, and the reasons why they aren’t followed on site. Only by knowing the reasons can we take targeted action
As for the reason, I think what was said on the third floor makes a lot of sense. If this isn’t done on site, in fact, many construction firms or companies do not follow the standards strictly; especially smaller firms, which often arrange their piping in a rather arbitrary manner. Therefore, what can be seen on site may not necessarily conform to the standards. Moreover, the regulations are quite general in nature; the scope of \"special circumstances that permit a straight turn\" is wide, and as long as I don’t follow the regulations, I can claim it to be a \"special circumstance.\" So I think as long as it meets the technical requirements, is easy to operate, and does not go against common sense, changes are possible.
