How to select pipeline rolling supports?
Thread Content
Do we only need to determine the material and the nominal pipe diameter? Are there any **standards or standard catalogues for rolling supports?**
Amazing, Wangshunyu! I heard for the first time that rolling supports are used for pipes to prop them up
If no information on this topic is available, the pipeline support and hanger manual of the East China Institute, series GH, can be used as a reference
You mean the sliding bracket, right? . . However, selecting the right type of support is not that simple. Factors such as the nominal diameter of the pipe, the temperature of the medium, calculations of pipeline stress, calculations of thermal displacement at the support points, and offset installation at the base of the support all come into play. Moreover, supports for steam pipes are not all the same; sliding supports, guide supports, and hangers are used in combination with each other.

It seems like I’ve heard of magnetic levitation supports somewhere before:funk:
We used rolling brackets quite often in the past; they have low friction, and we selected them from the manufacturer’s catalog. However, it also has drawbacks: it has built-in guidance, relies on line contact, requires high standards for the pipe support base plates, and its rollers tend to break, which causes a lot of trouble once they fail. If the pipe support falls out of the bracket after overheating, it will pull the bracket off when the temperature drops back down. Based on our many years of experience, it’s basically not needed anymore.
Why can’t I find it even after looking at this standard? . . Could you give me a model number? Broaden one’s horizons
