Technical Field

The invention relates to the field of high-temperature pipeline construction, in particular to a high-temperature pipeline heat-insulating structure.

Background

The high-temperature pipelines of the power plant are more, and the pipelines need to be arranged in a closer parallel or crossed mode due to the restriction of field space. The existing pipeline heat preservation method only preserves heat for a single pipeline. When a plurality of pipelines are arranged relatively close to each other, the pipelines need to be insulated jointly, namely, the first insulating layer is wound or wrapped on the plurality of pipelines at the same time in a cold state.

The problems existing in the existing stage of heat preservation construction are as follows: when the high-temperature pipeline operates, the expansion amount and the expansion direction of a plurality of pipelines can be inconsistent, and the existing pipeline heat-insulating material does not have the capability of absorbing expansion, so that the first heat-insulating layer is pulled to be cracked, and the heat-insulating effect is influenced.
