Can all the pipe supports on the pipe tray be guided ones?

Over long distances, pipe deformation can be severe; guide supports should not be used throughout the entire system in engineering applications

It is also necessary to properly set the fixing brackets

Of course not. As mentioned on the second floor, as the pipes grow longer, the displacements in various directions due to thermal expansion and contraction become significant, which ultimately leads to excessive stress and can cause damage such as cracking, especially in pipes carrying high-temperature substances like steam.

No, because you must leave some margin for the lateral displacement of the pipe; generally, a guide support is installed every 20 meters

Each case should be analyzed on its own; for example, sliding is the best option at bends. Because the elbow is the best location for natural compensation due to thermal expansion and contraction, using guide supports can easily damage the weld seam or flange

Hehe, it’s better to carry out stress calculations now, as many leaks have been observed on site; the damage is caused by improper pipeline layout and inadequate support structures, which result in excessive stress

If thermal expansion is not considered, light guidance is sufficient
Reply #92009-08-23
No, without fixed supports, the tube will experience uneven tension due to thermal expansion between the two tensions

Yes, it’s fine if thermal expansion isn’t a concern and no support is needed; in fact, in such cases it’s better to place the pipe on the crossbeam of the pipe bridge and allow it to slide freely (as a bare pipe). If insulation is present, then a sliding pipe support should be used. However, for pipes operating at lower temperatures, when high-temperature media such as steam flow through them, thermal expansion must be taken into account. Generally, stress analysis is required to determine the type of support at each location. What you mentioned is too general

Pipelines at normal temperatures can work in theory, but pipelines at high or low temperatures definitely cannot; detailed stress calculations are necessary.
