Can industrial pipes be made into an arch structure?

Can high-temperature industrial pipes be shaped into arches to address the issue of large spans?
I tried to model an arch, with horizontal straight sections on the left and right; two fixed supports were placed on those horizontal sections, and the arch was connected to the horizontal sections using elbows. The software gave me a message regarding this – what’s going on? Why is it modeled in this way as well, without any error messages?
Oil and gas transmission pipelines that cross rivers often feature such installations.
Oil and gas pipelines generally don’t have high temperatures, right?
Arch tube design is also quite common; it is suitable for rivers with a span of 60–80 meters, but not for larger spans
Is this done for steam pipes at 300-400℃?
High-temperature arch pipes are used more frequently than those at normal temperatures; on the one hand, this helps to address secondary stresses, and on the other hand, it enhances their own stability. If you go to the Jiangsu and Zhejiang regions, there are countless steam arch pipes for heating.
In the case of urban heat networks, which often cross roads and rivers, such systems are certainly used extensively. I’m not sure how common arch structures are among GC-type pipelines Also, regarding my model issue, do you know how to deal with it?
