Should the large tie rod compensator be insulated?
Thread Content
1. The design pressure for the power pipeline is 4.0 MPa, and the design temperature is 455°C. It was observed on site that the entire pipeline is insulated, including the large tie rod compensator. Question: Should the large tie rod compensator also be insulated?
Does it also belong to bellows? @Dawn bellows
Yes, it’s the large rod-type bellows compensator. Generally, bellows compensators should not be insulated as much as possible. However, I think that at such high temperatures insulation is necessary, but a flexible insulating structure should be used to prevent interference with the normal thermal expansion of the pipeline.
“A scalable insulation structure needs to be installed to prevent interference with the normal thermal expansion of the pipes. ”What does it look like? Based on standards?
