Expansion joints have high requirements regarding the location of their supports; the one shown in the picture is likely to fail soon.
No, it’s the inlet of a separator.
Generally, natural compensation is the preferred option for pipelines; expansion joints are used only as a last resort. Improper selection or support setup can damage the pipeline.
I’ve never seen supports installed directly under expansion joints~~They are usually placed at one end or both ends~~Also, insulation cannot be applied directly to the corrugated joints~~
I have a question: is there a standard that specifies that insulation cannot be applied to the corrugated joints?
I haven’t paid attention to the standards before~~ The installation guidelines provided by the expansion joint manufacturers state that insulation materials containing chlorine should not be used; moreover, the insulation layer must be installed on a protective cover surrounding the expansion joint, and it cannot be applied directly onto the bellows~~ This is mainly to prevent it from affecting the proper functioning of the expansion joint~~
