Guiding support, fixed support, and sliding support
Thread Content
This post was last edited by leiyuan on 2017-12-4 at 19:45. May I ask the teachers, where are guide bearings, fixed bearings, and sliding bearings used? Can guide supports be used at pipeline bends? Are there any mandatory requirements?
Aren’t all of these designed with calculations taken into account?:o
There’s a lot to say about this; there’s no fixed location for its installation, and the main purpose is to allow pipeline stresses to pass through while ensuring proper functionality in use. It relies more on experience and calculations.
I mainly want to know where guide bearings are used

I mainly want to know where the guiding supports are used, as the design does not specify the exact locations
The function of the guide bracket is to limit the radial displacement of the pipeline. First, it prevents the pipe from colliding with objects nearby; second, it prevents excessive displacement that could cause the pipe supports to fall off the brackets. It is also used next to compensators to ensure that these compensators function properly.

The pipeline is relatively long, and guide supports should be installed at both ends of the expansion joint； It is not suitable to install guide brackets at a certain distance on both sides of the rotary compensator, etc ； In general, the guide bracket prevents radial movement of the pipe, ensuring that it can only move in the direction of thermal expansion. Do not use guidance when natural compensation is employed.
Thank you, then guide bearings should be used before and after the expansion joint
